Publication No. 980673-024 Rev. A 1260-37 User Manual Chapter 3 MODULE SPECIFIC SYNTAX 1260-37 Module Specific Syntax The Module Specific Syntax for the 1260-37 Signal Multiplexer/SPDT Switch is required in the use of the OPEN and CLOSE commands. It will also appear in data output by the Master in response to the PDATAOUT and PSETUP commands. Syntax The Module Specific Syntax for the 1260-37 module is as follows: .
1260-37 User Manual Publication No. 980673-024 Rev. A Note that the SPDT circuit channel number is preceded by a “1” to distinguish it from the Multiplexer/Scanner circuit. For the SPDT circuit, Channels 00 to 39 correspond to channels 100 to 139 in the command syntax. The actual mapping of channel number to connector pins for the Scanner/Multiplexer circuit is given in Table 3-1, and for the SPDT circuit in Figure 3-2. Figure 3-3 shows the physical location of the 64-pin (2 Row) connector pins.
Publication No. 980673-024 Rev. A 1260-37 User Manual The response to the PSETUP command consists of a header on the first line. The header describes the model number, followed by a four-wire or two-wire to indicate the module setup. The next line designates the setup mode for scanning which, by default, is Break-Before-Make (BBM).
1260-37 User Manual Publication No. 980673-024 Rev. A The common output of channel 48 is the single channel of the 96 x I multiplexer, and the 48 HI and 48 LO connections make up the 96 channels. By closing the appropriate channel (0-47) and opening or closing channel 48, a 96 x I multiplexer is achieved. Table 3-1, 1260-37 Multiplexer/Scanner Circuit Channel Closure Channel interconnect for 1, 2 and 4-wire modes.
