6 1.0 Introduction 1.1 Purpose This document describes the interfacing characteristics of the Abbott CELL-DYN 1800 automated hematology analyzer when attached to a Host. 1.2 Definitions and Conventions Host: external computer or data collection system. CELL-DYN 1800: Abbott CELL-DYN This specification follows guidelines adopted at the Biomedical Instrumentation Interface Standards Conference held at the University of Florida in December 1980 and at the University of Texas in Dallas, April Signal designators and related characteristics follow EIA Standard RS232C as summarized in The Handbook of Computers and Computing, Seidman and Flores, Van Nostrad Reinhold, 1984; and Integrated Circuits Applications Handbook, Arthur H. Seidman, John Wiley & Sons, Numeric equivalents of characters are shown as hexadecimal (hex) values. 2.0 Mechanical Interface 2.1 Connector arrangement The CELL-DYN 1800 provides a standard DB-9 male connector, labeled COM1, mounted on the side of the instrument. Pins on the DB-9 connector: (standard RS pin assignments) Pin 1: Data Carrier Detect (DCD input) (monitored) Pin 2: Data to CELL-DYN 1800 (RD-receive data) (ACK/NAK, XON/XOFF) Pin 3: Data to Host (LIS, results) (TD transmit data) Pin 4: Data Terminal Ready (DTR) (set true) Pin 5: Signal Ground Pin 6: Data Set Ready (DSR) (monitored) Pin 7: Request to Send (RTS output) (set true) Pin 8: Clear to Send (CTS input) (monitored, if requested in Setup) Pin 9: Ring Indicate (RI input) (unused) 07H79-01 February 2003 Page 1 of 36

7 3.0 Electrical Interface 3.1 Voltage levels and electrical characteristics are as defined by the EIA RS-232C specification. 3.2 The maximum recommended cable length is 30 meters, or 100 feet. The actual maximum workable cable length is dependent on the environment of the site, the selected baud rate, and the equipment being connected together. 4.0 Data Interface The system can be configured for data transmission using the COMPUTER SETUP Menu. The configurable transmission parameters include data bits, stop bits, parity and baud rate. 4.1 The asynchronous method of data transmission (serial by bit) is used. 4.2 All information transmitted is in character form and is represented by 7-bit or ASCII. 4.3 Transmitted characters consist of one (1) start bit, seven (7) or eight (8) data bits (least significant first), one or no parity bit, and one (1) or two (2) stop bits. 4.4 Parity may be selected as none, odd, or even. 4.5 The transmission speed may be selected from 1200, 2400, 4800, or 9600 bits per second (bps). 4.6 With the exception of the control characters mentioned in Section 5.2, only printable ASCII characters (hex 20 to hex 7E) are used in a message.

8 5.0 Communication Protocol 5.1 Communication Modes RUN Menu Automatic Transmit Mode The User may select the Automatic Transmit mode on the COMPUTER SETUP Menu. This mode allows the automatic transmission of results during the RUN cycle. If Automatic Transmit mode has been selected, the user may also choose whether or not to transmit histograms along with the count data DATALOG Menu Transmit Mode On the DATALOG Menu, the user may select results from a single sample or from multiple samples for transmission. Only count data may be transmitted from the Data Log menu DISPLAY SPECIMEN Menu Transmit Mode On the DISPLAY SPECIMEN Menu, the user may request transmission of results from the specimen being displayed. Count data are transmitted. Histograms are also transmitted if the Automatic Transmit mode is selected in the COMPUTER SETUP Menu. 5.2 Transmission Control Transmission control is provided in two ways: 1) XOFF/XON protocol in which the Host transmits an XOFF character (hex 13) to stop transmission from the System and an XON character (hex 11) to re-start transmission; and 2) CTS (Clear To Send) hardware control. The XOFF/XON protocol has a 1.5 second time-out. If no XON is received for 1.5 seconds after an XOFF, then transmission resumes anyway. The CTS hardware control has no time-out. That is, no data transmission will be started with CTS false. However, the transmission will still time-out if at any one time CTS remains false for longer than the time-out selected in the COMPUTER SETUP Menu (see Section below). This is a different use and meaning for time-out, but it is needed to prevent the Host from indefinitely delaying the CELL-DYN 1800 from processing the next sample. Re-transmission requests are also supported and discussed in Section H79-01 February 2003 Page 3 of 36

9 5.3 Response from Host Between-Transmission Time-out The time-out interval after transmission of one message is programmable in the COMPUTER SETUP Menu from 100 milliseconds to 9.9 seconds in 100 millisecond increments. NOTE: The timer starts just as the ETX, which ends the message, is transmitted Release for Next Message The Host can release the CELL-DYN 1800 to send the next message by sending an ACK (06 hex) before the time-out interval passes. Otherwise, the CELL-DYN 1800 will begin transmission of the next message at the end of the time-out interval in above Re-transmission 5.4 Message Format If for any reason the Host requires re-transmission of the message, it signals the CELL-DYN 1800 by sending a NAK (15 hex) before expiration of the time-out. A message will be sent by the CELL-DYN 1800 a maximum of three (3) times. After that, the same conditions prevail as after a time-out. The Host may (it is desirable but not mandatory) acknowledge the retransmission with ACK or NAK. If ACK is sent, the CELL-DYN 1800 will immediately start processing the next record (if any). If NAK is sent, the record will NOT be transmitted a third time. Receipt of either the ACK or NAK will allow the CELL-DYN 1800 to move to the next record more quickly. The message format consists of the following elements: STX, ID SEGMENT, RESULT SEGMENT, CHECK SUM, ETX There are four (4) types of messages, each distinguished by its ID segment: WBC Histogram Message RBC Histogram Message PLT Histogram Message Count Data Message The four messages taken together represent all the results of testing a single specimen Each message begins with STX (hex 02) The Identification (ID) segment is described fully in Section The Result segment is described fully in Section The Check Sum is always provided and may be optionally processed by the Host to verify correct transmission. It is generated by taking the modulo-256 sum of all the characters in the message except the STX and ETX characters. The two-digit hexadecimal representation of the Check Sum byte is placed immediately before the ETX as two ASCII characters The ETX character (hex 03) is the last character of the message.

10 5.4.8 Message Length Each of the three Histogram messages is 1204 characters long. The Count Data message is 406 characters long. These message lengths count all characters from STX to ETX inclusive Data Representation 6.0 Identification (ID) Segment Numeric data are transmitted in fields of fixed length with zeros used to fill empty spaces on the left. Out-of-range numeric values are represented by strings of ">" characters (hex 3E), and undefined numeric values are represented by strings of " " characters (hex 2D). Alphanumeric data are transmitted in fields of fixed length enclosed in double quotation marks (hex 22). Within the quotation marks, the data are right-justified and blanks (hex 20) are used to fill empty spaces. Fields are separated by commas (hex 2C) For counting purposes, the STX mentioned in Section is taken as byte The Identification segment of each message identifies the type of message and the specimen the message represents. 6.2 Message Type Field 1 The Message Type field identifies the message. There are four message types: WBC Histogram Message Type "WBC" RBC Histogram Message Type "RBC" PLT Histogram Message Count Data Message Type "PLT" Type " " (3 blanks) 6.3 Instrument Type Field 2 The Instrument Type is an alphanumeric field of seven (7) characters enclosed in double quotation marks. The string for the CELL-DYN 1800 is sent as " CD1800". 6.4 Serial Number Field 3 The Instrument Serial Number is an alphanumeric field of twelve (12) characters enclosed in double quotation marks. It is not available in this release, so the field is transmitted as " " (twelve dashes). 6.5 Sequence Number Field 4 The Sequence Number is a numeric field of four (4) characters with a value ranging from 0 to H79-01 February 2003 Page 5 of 36

11 6.6 Specimen Type Field 5 The Specimen Type is the fifth field in the Identification Segment. It occupies a numeric field of two characters whose value identifies the specimen type as follows: 00: Patient type "PATIENT" 01: Replicate 1 "REPLIC 1" 02: Replicate 2 "REPLIC 2" 03: Replicate 3 "REPLIC 3" 04: Replicate 4 "REPLIC 4" 05: Replicate 5 "REPLIC 5" 06: Replicate 6 "REPLIC 6" 07: Replicate 7 "REPLIC 7" 08: Replicate 8 "REPLIC 8" 09: Replicate 9 "REPLIC 9" 10: Low Control "LOW CTRL" 11: Normal Control "NOR CTRL" 12: High Control "HI CTRL" 13: Background "BACKGRD" 14: Electrical Background "ELEC BKGD" 15: Calibrator "CALIBRATR" 16: Gain Adjustment "GAIN ADJ" 17: Auto Calibration "AUTO CAL" 6.7 Operator ID Field 6 The Operator ID is a alphanumeric field of three (3) digits enclosed in double quotation marks. If no Operator ID is specified, the field is transmitted as " ". 6.8 Specimen Date Field 7 The Specimen Date, giving the date on which the specimen was run, is an alphanumeric field of eight (8) characters enclosed in double quotation marks. The default format of the date is MM/DD/YY, where MM represents the month in two digits, DD represents the day of the month, and YY represents the year. The date format can be changed in the DATE/TIME Menu. 6.9 Specimen Time Field 8 The Specimen Time is a alphanumeric field of five (5) characters enclosed in double quotation marks. It gives the time at which the specimen was run in standard 24- hour format Specimen ID Field 9 The Specimen ID is an alphanumeric field of sixteen (16) characters enclosed in double quotation marks. If the specimen is a patient specimen, the Specimen ID is entered by the operator. Otherwise, the Specimen ID is generated by the CELL-DYN 1800 to identify special types of samples, such as controls. If not specified, the Specimen ID is transmitted as " " (16 dashes). See Section 6.6 (Field 5). Page 6 of 36 07H79-01 February 2003

12 6.11 Specimen Name Field 10 The Specimen Name is the tenth field in the Identification Segment. It occupies a text field of sixteen (16) characters enclosed in double quotation marks, and it is undefined except for patient samples Specimen Sex Field 11 The Specimen Sex field consists of one (1) character M or F enclosed in double quotation marks. If not entered by the operator, Specimen Sex is transmitted as a blank " " Specimen Date of Birth (DOB) Field 12 The Specimen Date of Birth field has an identical format to Field 7, except that Field 7 is automatically generated by the CELL-DYN If DOB is not entered by the operator, it is transmitted as "bb/bb/bb" where the bb s are actually 2 ASCII blanks each Dr Name Field 13 The Dr Name field is an alphanumeric field of twenty two (22) characters enclosed in double quotation marks Collection Date Field 14 The Collection Date field is an alphanumeric field of five (5) characters enclosed in double quotation marks. The format is MM/DD, where MM represents the month in two digits and DD represents the day. The year is not included. It gives the date at which the specimen was collected. If the Collection Date is not entered, it is transmitted as "bb/bb" where the bb s are 2 ASCII blanks as in Field 12 above Collection Time Field 15 The Collection Time field is an alphanumeric field of five (5) characters enclosed in double quotation marks. It gives the time at which the specimen was collected. If the Collection Time is not entered, it is transmitted as "bb:bb" ( bb s are 2 ASCII blanks each and : is the middle byte) Comment Field 16 The Comment field is an alphanumeric field of sixteen (16) characters enclosed in double quotation marks. NOTE: Fields 1 to 16 above are common in both format AND actual content for a given sample and, as such, are transmitted multiple times when histogram transmission is requested (first if sent with all three histograms and then again with the count record). Given today s typical transmission speeds and the lengths of the rest of the fields, the convenience of having the header information combined with each data group has been chosen over the absolute smallest or fastest transmission. Also, in the time frame of even normal sample processing, the transmissions (at 9600 baud) should take less than 4 seconds out of the 60 second (nominal) cycle time. 07H79-01 February 2003 Page 7 of 36

13 7.0 Results Segment 7.1 The results for each specimen are sent in the format described. All numeric fields are integers, and some need to be scaled by the Host. 7.2 Histogram Messages Refer to Table 1, Histogram Messages, and Table 2, Histogram Record Dump Scale Factor Field 17 The Scale Factor is a numeric field of five (5) characters. It is not implemented at this time and is therefore always transmitted as (5 ASCII zeros without the surrounding double quotes) Channel Data Fields 18 through Count Data Message The Channel Data fields are numeric fields of three (3) characters each, giving normalized counts for every channel of the designated histogram (WBC, RBC, or PLT). Data for each channel will occupy 4 bytes total since there will be a comma between each 3-digit value. Each value is rightjustified with ASCII zero 0 (not null) characters to keep the fields a fixed length. So a channel value of binary zero is transmitted as three ASCII zero characters (000). NOTE: A comma (,) follows the last field which immediately precedes the CRC characters. Refer to Table 3, Count Data Messages, and Table 4, Count Record Dump. The parameters reported by the instrument may be represented in any of four different sets of measurement units as follows: Set 1 Standard USA Set 2 SI Set 3 Modified SI (HGB/MCHC in mmol/l, MCH in fmol) Set 4 Modified SI (HCT/PCT in %) NOTE: The numeric values transmitted to the host are always sent in Standard USA units even if the unit of measure, also being transmitted, is Set 2, 3, or 4. To convert the integer transmitted in the field corresponding to a particular parameter to the correct value for that parameter in the units being used, the decimal point must be moved leftward from its implied position to the right of the integer. The description of each field gives a shift count indicating how many places to move the decimal point in each case. If, for example, the decimal point is to be moved two places to the left, a field value of becomes An integer representing the Units Set currently in effect is transmitted in the Units Set field (Section ). For Units Set 3, the HGB, MCH, and MCHC values must be multiplied by after the decimal point has been positioned. The units of measure associated with the four sets are explained in the CELL-DYN 1800 Operator s Manual. Page 8 of 36 07H79-01 February 2003
