I'm using an iTack IP2Serial gateway, configured for 9600 baud, 8N1 format, no handshaking.
I plugged it into the DB9 port in the top of the back, using a null modem cable.
I can't seem to get the receiver to pay attention to any commands, including the "POWER ON" command and the "REQUEST STATUS" command that are supposed to work in standby mode.
I checked out the signals coming out of the DB9 null modem cable using a logic analyzer, and they seem like legit RS-232 serial signals.
Is there something I'm missing here? Do I need a non-standard (non-null-modem) cable? Do I need hardware handshaking? Do I need to perform some magic incantation on the receiver to make it pay attention?
Btw, here are the documents I'm using for the serial communication format for the STR series receivers:
