Note: Termina on resistors (R=120 Ohm) are used to match impedance of a node to the impedance of the transmission (TX) line.
Termina on resistors should be placed only at the extreme ends of the TX data lines, and not more than two termina ons should
be placed in any single segment of an RS‐485 network. The termina on resistors may not be needed for your applica on.

The user must supply a 9‐30 VDC or 9‐24 VAC power source and a CAT 5
Ethernet cable. Lantronix offers
The xPress DR+ supports RS‐232 (up to 230,400 bps) via RJ45 connectors.
It also supports RS‐422/485 via screw terminals (Serial Port 2 only).
Note: Serial Port 2 supports RS232, RS422, and RS485, but only one mode
at a me. You can use either the RJ45 connector or the terminal block, not
both.
The supplied Lantronix P/N: 500‐103‐R serial cable can be used to con‐
nect port 1 of xPress DR+ to a PC's com port for configura on using a
terminal emula on applica on. This cable is pinned to provide full serial
control to an RS232 DTE device.
Refer to the xPress DR+ User Guide for informa on on configuring the
xPress DR+ through the serial interface.
