nxc-com2 problems

locknar

I have a netlink master connected to a ncx.com2, and an epson projector, when you push the TP the status lights light, the transmit to the ethernet lights, the nxc-com2 blinks green showing connection to the master, when you push the TP the transmit light on the nxc-com2 lights up, but the receive does not light up(and projector does not power on). I have check my RS-232 cabling and even reversed pins 2and 3, this setup serial string works from com1 of the master. The nxc-com2 shows up in the online tree as device 5002, is there another definition or what am I missing to make this work?

Put a loopback adapter on your com port (or just jump pins 2 and 3 together temporarily) and use a terminal program to make certain it didn't blow out. If that works, do the same at the end of your wire, to make sure it didn't get damaged. If those tests work, the port on the projector is suspect, especially if it used to work but now doesn't.
