4.1. Antenna Connection
The external SMA antenna connectors are positioned on the lower side of the reader.
The maximum tightening torque for the SMA sockets is 0.45 Nm (4.0 lbf in).
For supplying a DC voltage to external components e.g. the UHF antenna multiplexer ID
ISC.ANT.UMUX, it is possible to enable a supply voltage (24 V DC / max. 500mA) on the antenna
cable. This need to be configured in the reader.

CAUTION:
Exceeding the tightening torque will destroy the plug.
The activation of the DC voltage on the antenna cable can damage the antennas from other
manufacturers. It is recommend to use high resistance UHF antennas. For any further ques-
tions please contact the technical support.
