Installation and Initial Setup
This section describes how to install the VESR4x4 Serial Server and configure
the device.
Note: In this section devices to be connected to the serial server’s serial connections are simply referred
to as the “serial device”.
Connecting the Power Supply
Connect a DC power supply to the power terminals on the side of the serial
server. Polarity of the wires is indicated underneath each connector.
Acceptable voltages are between 10 VDC and 58 VDC. The power supply must
be capable of supplying 6 watts.

NOTE: the terminal block must be used for Class 1 Division 2 applications; the
barrel jack cannot be used for these applications. See the specification tables
for further information.
Connecting VESR4x4 Serial Servers to Serial Devices
VESR4x4 Serial Servers can be connected to serial devices using RS-232, RS-
422, RS-485 2-wire, or RS-485 4-wire communication. VESR4x4D models use
DB-9M connectors and VESR4x4T models use 5-position terminal strips.
