2.4 POWER & WIRING
The information presented below is provided to assist the installer in determining the amount
of power that will be required by the Gateway and its Subnet network.
2.4.1 Power Requirements
The Gateway requires an electrical supply voltage of 12 to 30 Vdc. In addition, each RFID
controller connected to the Gateway via the Subnet16™ network will also require power. Use
a regulated power supply that is capable of delivering the requirements listed in the
Technical Features.
NOTE
Power is applied directly to the Subnet16™ Network trunk and distributed
through drop cables to the Gateway and RFID controllers. By positioning the
power supply near the middle of the network, you can limit voltage drop at
the ends, (see Appendix B for network layout diagrams).
The following information is provided to assist you in determining the power requirements of
your RFID application.
