7 USBAN-I-mini User Manual hapter 2: Device Installation 2.1 AN-bus onnector The USBAN-I-mini interface card is integrated with one AN-bus channel, which connects with the actual AN-bus network through DB9 pin-type socket or DB9 hole-type socket. Table 2-1 shows the pin definition of DB9 socket. The pin definition complies with the DeviceNet and ANopen standard. Table 2-1: AN-bus signal connection (DB9 socket) DB9 Pin-type Socket Pin Signal Description 1 N. Not used 2 AN_L AN_L signal line 3 AN_GND Reference ground 4 N.. Not used 5 AN_SHIELD Shielded line 6 AN_GND Reference ground 7 AN_H AN_H signal line 8 N.. Not used 9 N.. Not used The AN-bus signal of DB9 socket can be converted to the 5-pin OPEN5 connector through the optional DB9OPEN5 converter. The OPEN5 connector is easier to connect and its interface description is shown in Table 2-2. Table 2-2: Pin assignment of DB9OPEN5 converter (OPEN5 socket) OPEN5 Socket Pin Signal Description 1 V- Negative network power supply 2 AN_L AN_L signal line 3 SHIELD Shielded line (FG) 4 AN_H AN_H signal line 5 V+ Positive network power supply 2.2 Signal Indicator The USBAN-I-mini interface card contains one dual-color SYS indicator and one RUN indicator to indicate the operating status of device. The function of two indicators is described in Table 2-3 and Table

8 USBAN-I-mini User Manual Table 2-3: Indicators on the USBAN-I-mini interface card Indicators Status Function Red Indicates the device initialization status. SYS Green Indicates USB interface signal. RUN Green Indicates AN interface operating status. When the USBAN-I-mini interface card is powered on, the SYS indicator is red to indicate that the device is powered on and the system is being initialized. If the SYS indicator is off, it indicates that there is system power supply fault or serious system error. After the USB interface is connected properly, the SYS indicator changes to green color from red color. When there is data transmission through the USB interface, the SYS indicator becomes green and flashes. When the RUN indicator lights, it indicates the AN controller has finished initialization and enters into normal operating status. Table 2-4: Indicator status of USBAN-I-mini interface card AN Indicator Status RUN indicator is off. RUN indicator is on. AN-bus Status The connection between AN controller and AN-bus is off. The AN bus is operating properly. 2.3 System onnection AN-bus onnection When the USBAN-I-mini interface card is connected to AN-bus Bus, users only need to connect AN_L with AN_L signal, AN_H with AN_H signal. The AN-bus network uses linear topology, and the two terminals of bus should be connected with a 120Ω terminal resistance; if the number of nodes is greater than 2, the intermediate node does not need to connect with a 120Ω terminal resistance. For branch connections, the connection distance should not exceed 3m. The AN-bus connection is shown in Figure 2-1. Terminal Resistance Terminal Resistance Figure 2-1: AN-bus network topology Notes: The AN-bus can use common twisted pair or shielded twisted pair. If the 7

9 USBAN-I-mini User Manual communication distance exceeds 1Km, the section area of cable should be greater than 1.0mm 2, which depends on the specific distance. Generally, longer the communication distance is, greater the section area of cable is Bus Terminal Resistance In general, the two terminals of AN-bus network should be added a terminal matching resistance to improve communication reliability, as shown in Figure 2-1. The value of terminal matching resistance is determined by the characteristic impedance of transmission cable. For example, if the characteristic impedance of twisted pair is 120Ω, two terminals of AN-bus should be connected with a 120Ω terminal resistance. In addition, the USBAN-I-mini interface card uses FreeScale M33901WEF high-performance AN transceiver; therefore, if the other nodes on the network use different transceivers, the terminal resistance must be calculated separately. The USBAN-I-mini intelligent AN interface card is integrated with an internal 120Ω terminal resistance, without the need of external terminal resistance. The USB port on the USBAN-I-mini interface card is compliance with USB1.1 specification, and can be connected to a P with USB1.1 or USB2.0 interface. 8

29 USBAN-I-mini User Manual Appendix A: AN Message Filter Settings The AN message filter of this converter is designed based on the PeliAN mode of PHILIPS SJA1000 AN controller. The filter of SJA1000 is composed of 4 groups (4 bytes) of acceptance code register (AR) and 4 groups (4 bytes) of acceptance mask register (AMR). The AR value is predefined acceptance code value, and the AMR value indicates whether the corresponding AR value is used for acceptance filtering. However, some registers of the filter are not used in some modes of the SJA1000. For ease of use, only the actual value of the filter is involved in the configuration software and the irrelevant data is discarded. The general rule of filtering is that each acceptance mask bit corresponds to an acceptance code bit. When the acceptance mask bit is 1 (that is, don t care), it indicates acceptance regardless of whether the received frame ID bit is equal to the corresponding acceptance code bit; however, when the acceptance mask bit is 0 (relevant), it indicates acceptance only if the received frame ID bit is equal to the corresponding acceptance code bit. And only when all single bit comparisons signal acceptance, AN controller will receive the frame message. The filter mode is divided into single filter and dual filter. The filter is slightly different between standard frame and extended frame. If the user-defined acceptance mask is set in the configuration software, all filter function is enabled, which is described as follows: A.1 Single Filter onfiguration In this filter configuration, one long filter could be defined. The bit correspondences between the filter bytes and the message bytes depend on the currently received frame format. Standard frame: if a standard frame format is used, only part of data bits (lower 11 bits) of the first two AR bytes (AR3 and AR4) is used for acceptance filtering; similarly, only lower 11 bits of AMR3 and AMR4 are used for acceptance filtering. If a bit in AMR is 0 (relevant), when the corresponding bit (such as, AR1.0 corresponds to AMR1.0 and ID.00) in AR is equal to the received frame identifier bit, it indicates acceptance (logic 1); when the values of two bits are not equal, it indicates not acceptance (logic 0). On the other hand, if a bit in AMR is 1, it indicates acceptance (logic 1) regardless of whether the corresponding bit in AR is equal to the received frame identifier bit. For a successful reception of a message, all single bit comparisons have to signal acceptance, as shown in Figure

30 USBAN-I-mini User Manual Acceptance code Acceptance mask Received frame identifier Message bit Acceptance code bit Acceptance mask bit bit x of data byte Acceptance ode Register Acceptance Mask Register Accepted Not accepted Figure 8-1: Single filter configuration, receiving standard frame messages Extended frame: when an extended frame format is used, since the frame identifier is 29 bits, part of data bits (lower 29 bits) of four AR bytes is used for acceptance filtering; similarly, only lower 29 bits of AMR are used for acceptance filtering. For a successful reception of a message, all single bit comparisons have to signal acceptance, as shown in Figure 8-2. Acceptance code Acceptance mask Frame identifier Filter 1 Acceptance mask bit Acceptance code bit Acceptance ode Register Acceptance Mask Register Frame identifier bit Accepted Not accepted Filter 2 Acceptance code bit Acceptance mask bit bit x of data byte Figure 8-2: Single filter configuration, receiving extended frame messages. 29

31 A.2 Dual Filter onfiguration USBAN-I-mini User Manual In this filter configuration, two short filters can be defined. A received message is compared with both filters to decide whether this message should be copied into the receive buffer or not. If at least one of the filters signals an acceptance, the received message becomes valid. The bit correspondences between the filter bytes and the message bytes depend on the currently received frame format. Standard frame: for a standard frame, it means the acceptance filtering is performed for the received frame identifier in the case of two single filters. The acceptance logic is shown in Figure 8-3. For a successful reception of a message, all single bit comparisons of at least one complete filter have to signal acceptance. The message frame can be received only when at least one filter signals acceptance. Filter 1 Received frame identifier Filter 2 Filter 1 Acceptance mask bit Acceptance code bit Acceptance ode Register Acceptance Mask Register Frame identifier bit Accepted Not accepted Filter 2 Acceptance code bit Acceptance mask bit bit x of data byte Figure 8-3: Dual filter configuration, receiving standard frame messages. Extended frame: for an extended frame, the two defined filters are identical. Both two filters only compare the first two bytes of extended identifier (i.e., ID.28~ID.13), not the whole 29 bit identifier, as shown in Figure

32 USBAN-I-mini User Manual For a successful reception of a message, all single bit comparisons of at least one complete filter have to signal acceptance. The message frame can be received only when at least one filter signals acceptance.
