4 - Command Set
The command set for both RS-232 and Ethernet is as follows:
Set Attenuator
Syntax:
SAx y <CR>
x = attenuator number to control
y = attenuation value to set the attenuator to
<CR> = carriage return
Description: This command sets attenuator “x” to “y” attenuation in dB.
Examples:
SA1 0 <CR>
Sets attenuator 1 to 0dB.
SA2 63 <CR>
Sets attenuator 2 to 63dB.
SA3 7 <CR>
Sets attenuator 3 to 7dB.
Notes:
There must be a space between the “x” and “y”.
There must NOT be a space between the “SA” and the “x”.
“x” must be 1 (because there is only one programmable attenuator in this system).
“y” must be between 0 and 63 (attenuation range is 0-63dB x 1dB).
Command is not case sensitive, but must be terminated by a carriage return.
Read Attenuator
Syntax:
RAx <CR>
x = attenuator number to query
<CR> = carriage return
<LF> = line feed
Description:
This command returns the attenuation setting for attenuator “x”.
Examples:
SA1 22 <CR>
Sets attenuator 1 to 22dB.
RA1 <CR>
Reads value of attenuator 1. Sends back “22dB <CR> <LF>”.
SA2 9 <CR>
Sets attenuator 2 to 9dB.
RA2 <CR>
Reads value of attenuator 2. Sends back “9dB <CR> <LF>”.
SA3 0 <CR>
Sets attenuator 3 to 0dB.
RA3 <CR>
Reads value of attenuator 3. Sends back “0dB <CR> <LF>”.
Notes:
There must NOT be a space between the “RA” and the “x”.
“x” must be 1 (because there is only one programmable attenuator in this system).
Command is not case sensitive, but must be terminated by a carriage return
