rs-232 and rs-485 Communications
The LCR-II is capable of interfacing with RS-232 and RS-485 communication protocols. Data connections for these
protocols is made at the j2 and j3 terminal blocks. For standard RS-232 terminal, (other than the Lap Pad), the red
+Vo input wire should be connected to J3-47.
A jumper, located on the left side of the CPU board, can also affect communication protocol. The jumper should stay
in the B position for most applications; however, to use a lap pad (PN E40301 and E403011) the jumper must be
moved to the A position. See the diagram and the table below.
