20. [...S]
This command saves the configuration
command being sent in memory. Send the
command [I1O*S] to switch IN 1 to all outputs
and save the setting. After power-up or [CLR],
IN 1 will be connected to all outputs.
21. [AFB]
This command enables/disables the command
acknowledgement feedback, “[ ]”, from the
UT250-101. This setting is automatically saved
to memory and can only be changed by sending
the [AFB] command a second time. Use this
command when sending a large number of
commands with no delays, or when repeatedly
sending commands with no delays.
Command Format: [AFBm]
m = 1 for ON, 0 for OFF
Example:
Send 16 commands to the UT250-101 to
initialize the card. The required commands are
as follows:
[I1O1A],
[I2O1B],
etc.
Send the [AFB] command first, and then the
switching commands.
[AFB0],
[I1O1A],
[I2O1B],
etc.
[AFB1]
In the above example, the brackets, “[ ]”, will not
be displayed after each command is executed.
22. [SIDn]
This command sets the UT250-101 to a new
unit ID. When assigning multiple IDs to several
units, connect only one unit at a time to the
RS-232 bus.
Command Format: [SIDn]
n = Unit ID (n = # from 1 to 9)
Example:
There are two UT250-101 units on the RS-232
bus, but they need to be controlled individually.
Connect only the first unit to the bus and then
send [SID1]. This unit is now U1. Disconnect the
first unit and connect the second unit. Now send
[SID2] to the second unit. The second unit is
now U2.
23. [RSI]
This command resets the unit ID to U0.
Command Format: [RSI]
Example:
Send the command [RSI] to reset unit ID U1
assigned above back to U0.
