1260-38 Module
Specific Syntax
The Module Specific Syntax for the 1260-38 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 1260-38 Multiplexer/Scanner
module is as follows:
<COMMAND> relay designator> [;<relay designator>]
where:
<relay designator> ::= <module address>.<channel range>
[,<channel range>...]
<channel range> ::= <channel descriptor>[-<channel descriptor>]
<channel descriptor> ::= <interconnect><mux select><channel>
<module address> ::= 1.. 12
<interconnect> ::= 0 to 9
Where:
0 = multiplexer channels.
1 to 8 = multiplexer interconnect relays.
9 = one-wire high/low select.
<mux select> ::= 00 to 15
For two-wire mode: selects one of 16 1 x 8 multiplexers.
For four-wire mode: selects two of 16 1 x 8 multiplexers.
Only even number multiplexers are allowed. Selecting
multiplexer 00 will also select same channel on next
multiplexer in sequence, in this case multiplexer 01.
<channel> ::= 0 to 7
0 to 7 for multiplexers
0 to 2 for interconnect relays
0 to 7 for one-wire relays
NOTE
The <module address> used here is not the VXIbus
