VX4380 256-Crosspoint Relay Matrix Module User Manual
3–19
[ROUTe:]OPEN <channel_list>
[ROUTe:]MODule:DEFine
[ROUTE:]CLOSE:DWELl
OUTPut:TTLTrg<n>[:STATe]
A one dimensional <channel_spec> consists of a single ASCII-encoded decimal
integer. The value of a one dimensional <channel_spec> can be determined from
a three dimensional <channel_spec> by using the following formula:
((section - 1) × 64) + ((row - 1) × 16) + column
where variables “section”, “row”, and “column” are section, row and column
numbers specified in a three dimensional <channel_spec>.
For example, the channel spec 3!10!2 specifies the relay that connects row 3 to
column 10 in section 2. The equivalent one dimensional <channel_spec> is equal
to ((2–1) × 64) + ((3–1) × 16) + 10 = 106.
This command closes the relays specified in the <channel_list> portion of this
command. After these relays are closed, a delay specified in a previously issued
[ROUTe:]CLOSe:DWELl command is generated. This command is used to
assign a close delay to each module controlled by an Option 01 daughter board.
If more than one module is specified in the <channel_list> argument of the
[ROUTe:]CLOSe command, the longest dwell time assigned to any of the
specified modules is used. After this delay, VXI TTL triggers that have been
enabled by a previously issued OUTPut:TTLTRG<n>:STATE command are
pulsed low for 3 msec.
In this example, the Option 01 is installed on a VX4380 Module. Two additional
VX4380 Modules are installed in consecutive slots to the right of the first
VX4380. The default module names for these three modules are m1, m2, and
m3. These module names may be altered with the [ROUTe:]MODule[:DEFine]
command.
