Overview DPS s -Channel ASCII MUX allows you to connect up to eight ASCII data sources to one ASCII port on an IAM or T/MonXM master. The master controls the MUX to route data to the appropriate port. Each channel has a K buffer that allows data to be moved between ports at different data rates. Variable Data Rates In addition to switching between multiple ports, the Channel ASCII MUX will select a preset data rate for each port. Available data rates are 00, 00, 00 and 900 Baud. T/MUX Software The MUX is programmed for various parameters with T/ASCMUX software, running under T/Config software on a personal computer. The craft port on the front panel is easily accessed any time the configuration needs changing. Downloadable Firmware Future product upgrades will be easy to install with the downloadable firmware. Simply connect a P.C to the craft port and load the new firmware from a diskette. The -Channel ASCII MUX is available with wire-wrap pins for external connection or with DB9 connectors. When the ASCII MUX is used the T/MonXM or IAM master must be equipped with the ASCII MUX and ASCII Processing software modules. The MUX consists of nine interface ports interconnected and controlled by a processor. Associated with each port is a docking module socket that allows the physical interface to the outside world to be configured to match the associated communications channel or device. This model of the ASCII MUX is equipped with RS interfaces on each port. The ASCII MUX is housed on a plug-in board that fits in a -/" rack-mount housing. The back of the housing provides DB9 connectors for connecting the associated devices. The actual MUX board can be changed rapidly without removing any of the connections. The front panel of the ASCII MUX provides LEDs for monitoring unit activity and a craft port for configuration. There is a fuse alarm indicator on the front panel and a fuse alarm output relay that activates when the fuse blows. the ASCII MUX operates on either - or - Volts DC, depending on the option. (Options are described in the Options and Model Numbers section on page.) T/kda T/ASCMUX Fig. - ASCII MUX Configures at the Front Panel Craft D-PC-0-0A-XV OG09

RS Fig. - ASCII MUX Routes Data by Microprocessor Control Connect power wires to the wire wrap J or to the connectors in back of the MUX. See Hardware Connections elsewhere in this guide for wire wrap or connector pin layouts. Connect communications lines to other devices to the MUX. Verify that the power is correct for the option (- or - VDC). See Options and Model Number section at the end of this Operation Guide. Insert the fuse in the fuse holder on the front panel. Connect the MUX Craft to a a dumb terminal or a P.C. with terminal emulation software. Refer to the Configuration Section below for more information. Configuration The MUX is configured with a program called T/ASCMUX. T/ASCMUX runs under a host program called T/Config, which can host configuration software for a variety of DPS products. T/Config is included on the disk supplied with the MUX unit. If T/ASCMUX is being run on a computer that already has T/Config installed, we recommend that you re-install the T/Config on the T/ASCMUX disk to be sure the latest version is running. T/Config and T/ASC MUX Install Place the T/ASCMUX disk in the A drive and type a:<enter>. Type TINSTALL <ENTER>. Follow the directions on the screen.

T/MonXM Implementation To prepare the T/MonXM WorkStation or IAM to utilize the ASCII MUX, a port number must be defined for the MUX and a phantom port (called a Job ) must be defined for each of the eight MUX ports (or less, if not all ports are currently used). Proceed as follows:. Prepare all ASCII rules according to the T/MonXM manual Section M (for regular ASCII) or M (for Auto-ASCII).. Select Remote s from the Parameters Menu.. Select an RS port for the ASCII MUX. Select DCP(F) Interrogator for the Usage field. Enter " in the address field. Make appropriate entries in the other fields.

Enter appropriate information in the rest of the fields. (See Fig. ) Fig. - Select ASCII MUX for the Device Type Field. Do not define alarm points for this port and device.. Press F0 to exit the Remote Device Definition screen. The Remote screen will appear. Use the N key to advance to port 0 (the screen will indicate Job 0"). Job 0 represents one of the MUX ports. Press F to define the Data Connection. (This defines the MUX port to be used for this Job.) Refer to Fig.. From the default box select one entry from N. to N., where N= the defined T/MonXM port number and. to. = the MUX port number. Only the available MUX ports will be listed. Mux ports may be assigned in any order. Fig. - Fill in Remote Parameters Fields per Table H Table H - Field s for the Remote Parameters Screen, Job # 0 and Up Field Job (#) Phantom port number. Jobs 0 to will be available once a device has been defined as ASCII MUX. Usage Select from default box. Default is HALTED. ASCII INTERFACE gives port full alarm and craft interface ability. CRAFT INTERFACE gives port craft interface ability only. Handshaking Select None, Xon/Xoff or Rts/Cts. Default is None. or Craft Optional 0 Character description. Full Duplex Y=Full Duplex. N=Half Duplex. Craft Interface only. Alarm Alias Number of port whose already defined data base you wish to use for this port. Leave blank for none. If used, enter alias port number, then press F and set device rules. Template To use a pre-defined template, enter the template number here. (0 through 0, leave blank for none.) Auto Databasing If Auto Data-basing is being used with the device connected to this MUX port, enter Y. If regular ASCII is used, enter N. 9. Press F to access the Devices screen. Enter information as for regular ASCII (T/MonXM Manual, page M-) or Auto ASCII (T/MonXM Manual page M-). 0. Press F to access the Point screen. Enter information as for regular ASCII (T/MonXM Manual, page M-). Point information is not applicable to Auto ASCII. When complete, use F0 to return to the Remote Parameters screen. Press N to move to the next Job # or use F0 to exit. D-PC-0-0A-XV OG09
