Table 1 – Jumper/Mode Table

The top jumper sets DB9 connections for either 232 or 422/485

RS-232 operation requires setting only the Top jumper.

The middle jumper sets the RS-422/RS-485 transmitter for RS-485 or RS-422 operation. In RS-485 mode, the transmitter is tri-stated when not sending data.In RS-422 mode, the transmitter is always enabled.

The bottom jumper sets the RS-422/RS-485 receiver for half-duplex RS-485 operation or full-duplex RS-422/RS-485 operation. In Half Duplex RS-485, the Receiver is Enabled when not transmitting. In Full Duplex RS-422/485 operation, the receiver is always enabled.
