Remote Operation
7.4.8 *RST
Syntax
*RST
Description
This command performs a device reset.
This will set the instrument so that all switches are in the default state.
For SPnT switches the default state is: all RF ports are open (position 0).
For a transfer switch the default state is: position 1 is closed.
Possible error codes
11, 12, 13
Timing
Before issuing any other command after a *RST use the following
considerations.
The *RST command is ‘translated’ by the internal controller board to command,
on the CAN bus level, each switch to position 0 (open). The amount of these
commands depends on the amount of switches present in the matrix.
Each switch requires approximately 10-15ms to switch position. So to execute a
*RST command (to open all positions without verifying the switch’s positions)
will require at least n x (10 - 15ms), where n is the number of switches in the
matrix.
7.4.9 *STB?
Syntax
*STB?
Description
Query the Status Byte Register
This command is similar to a Serial Poll but is processed like any other
instrument command. This command returns the same result as a Serial Poll
but the Master Summary bit is not cleared if a Serial Poll has occurred.
Result
STB decimal value which corresponds to the binary-weighted sum of all bits
set in the register.
Note: This command can NOT be concatenated with other commands. It must
be issued as a single command.
