J21 Serial Connector
16.1 Description
Note: Only one connector, J21 or J22 can function at a time. Either use J21 to connect a serial device for PC Log
Reporting,oruseJ22toconnectaDMPWirelessdeviceoranLX-Busdevice.Operationisdeterminedbywhereyou
install the jumper on the J23 6-Pin header. The maximum line impedance is 100 Ohms.
To enable J21 to operate in RS-232 mode, place a jumper on the two pins next to the letter “R” on the J23 6-Pin
headerandbrieyresetthepanelusingtheJ16jumpertoactivatetheselectedoperation.Panelprogrammingusing
