EDFA-B-C 17dBm Rev. B

4.4 RS232 control
If dip switch 7 (“A_M”) is set OFF (Manual), the GYDA/dip switch control over the EDFA will
halt and the RS232 input will be enabled (RS232 output is always on). Bitrate 9600, 8N1 (8
databits, no parity, 1 stop bit). A typical prompt will be “MSA::EDFA>”. When the prompt
returns, the module is ready for a new command. There is an option to set the bitrate of the
EDFA module to something else than 9600, but this will disable autonomous/GYDA
operation until reset back to 9600.
The following table lists the most useful commands (the HELP command will list all
commands):
