RS-232 Transceiver Enable Jumper (Option)
If stuffed, the jumper JCOM may be used to enable/disable the local RS-232E transceiver.
Installing the jumper enables the transceiver, removing the jumper shuts down the transceiver.
Be sure not to enable both, the CC3-CAJUN local transceiver, and the CCY-RIO rear I/O
transceiver, in order to avoid signal interference.
