Sorry to bring up a way old thread.

But believe it or not the boardroom were doing is my first life experience with RS232...Shocking right? im used to IR and IP control or already terminated RS232

Because im new at this I am completely lost at how to connect The RS232 bare end to the Crestron MPC-M5 Controller. When I striped the cable (one end has the RS232 connector already attached) I found 3 wires wrapped in shielding with a drain wire. On the MPC-M5 terminals I have TX-RX-Grd. So what colors go to what? I assume the drain wire goes to Grd (for ground)

We are using an Optoma HD1060 projector. I saw the RS232 pin out in the manual but im not sure if ill have to adjust the pins on the Terminated End or not.

Thanks all! I appreciate it.

ohh, here is the model number of the cable were using. Its from Crestron CBL-KSERIAL-DB9-L-P-50
