This depends on the model number of the meters in question. The CM3000, CM4000, and PM800 all use the same display cable.

Despite the different pinouts, both display cables utilize a 6 pin RJ-11 jack with 26 AWG wire. Both cables are RS-232, thus 50ft is the maximum length. If the displays or cables are interchanged, no damage will occur. The pinouts are shown below:
