Use "No-Protocol" with TXD(236) and RXD(235). Applying these instructions is described in manual W451.

I would have dip switches 4, 5 and 6 OFF on the CIF11 and then your data string would need to have a CR+LF as a terminator. Of course the Baud rate, parity, data bits and stop bits would need to match on the other device.
