Command Codes

CLOSE

CNF

DLY

For any command that causes relays to be operated
(e.g., CLOSE, OPEN, or RESET), allow 40msec to
3msec per relay operated relay settling time or
monitor the READY bit of the status byte waiting till
the 1260 reports that it is ready.
CLOSE <module address>.<module specific syntax> [;<module
address>.<module specific syntax>]....
This command causes one or more connections on a switching
module to close. Any number of connections in more than one slot
may be closed in one CLOSE statement if the <module
address>.<module specific syntax> sections are concatenated
using a semi-colon (;). Refer to the individual module sections for
the <module specific syntax> to be used for each switching
module.
CNF <ON|OFF>
This command turns the 1260 Confidence Test On or Off. The
Confidence Test checks that the state of all relays is as
programmed, and causes the Option 01 to assert the VXI Request
True exception after each OPEN or CLOSE command is
processed if an error is detected. A character string detailing the
failure may be obtained from the 1260-01 in response to the YERR
command. The character string the Confidence test causes the
Option 01 to generate is <module address>.51. <module address>
is a three digit number that is the address of the module slaved to
the 1260-01. 51 is the error code associated with a Confidence
Test failure. A GPIB/VXI Resource Manager will cause the
assertion of the GPIB SRQ line in response to the Request True
assertion. The default (power-up) state for the Confidence Test is
OFF.
DLY <value>
Command is used to cause a delay between the last relay closure
after a command string is processed, and the SYNC OUT pulse.
<value> may be 0-655 ms, and is set to zero at power up.
