2.1. RS-232 (Interactive & Block modes)

Interactive and Block modes support the 3-wire RS-232 configuration with TXD,

RXD and signal common. The cable requires an overall shield to protect against

electrical noise. Xon and Xoff can be used for communication handshaking.

2.2. RS-422/485 (Interactive & Block modes)

Interactive and Block modes support the 3-wire and 5-wire RS-422/485

configurations. The 3-wire configuration has both transmit and receive on the same

pair of wires plus a signal common. The 5-wire configuration has differential signal

pairs for transmit and receive plus a signal common. In both configurations the

signal pairs must be twisted and surrounded by an overall shield.

NOTE:

When using 3-wire RS-422/485, Jumper JP4 must be in position “B”.

Refer to section 2.4 for instructions.
