DC INPUT
Power to REX is supplied from the 12VDC power adapter via the DC jack input. If using user-supplied power
supply, observe voltage polarity and voltage level. REX operates on 12VDC input but can accept supply
voltage up to 24VDC. Do not exceed the recommended input voltage, exceeding which will damage REX.
Ethernet
The RJ-45 connector connects REX to the computer or network using Cat5 UTP cable. For connection to a
single PC, use a Ethernet cable supplied with the unit. A hub or Ethernet switch is not necessary for direct
REX to PC interface. REX can be used as a standalone system, or connected to the local area network
(LAN). A LAN connection gives greater flexibility as well as enabling REX to work with other networking
devices.
Antenna
This SMA connector interfaces the external antenna to the internal GSM modem of REX. Choose suitable
antenna for your installation. The SMA mount Antenna supplied, as standard accessory is the unity gain
antenna. This antenna is suitable for most installation. If the location has low GSM signal strength, use high
gain antenna or outdoor type. Check with your distributor for suitable antenna alternatives.
