3.1.2 RS-232C connector specification
The NJR’s RS-232C connection is supported by a 3-position terminal block.
Insert and secure the wires from the RS-232C cable into the supplied 3-position terminal block, and then
insert the terminal block into to the mating connector on the NJR-T01SDI.
AWG28 to AWG16 conductor gauge is recommended. The recommended wire strip length is 0.28 in. (7 mm).
Short RTS/CTS and DTR/DSR as needed.
