Altinex UT250-101 manual 20. ...S, Afb, SIDn, Rsi

DESIGNER SOLUTIONS

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 UT250-101to 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 UT250-101to 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 UT250-101units 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.
