NSTALLATION GUIDELINES

1.5.1 Hardware Requirements

The following components are required for a complete Subnet16 RFID system:

 One Subnet16 DeviceNet Gateway Interface Module

 One ControlLogix PLC or other DeviceNet-capable host

 One to 16 RS485-based RFID controllers (Cobalt or HF-0405-Series)

 Adequate length cabling, connectors and terminators

 Sufficient power, supplied via DeviceNet network cabling, capable of

powering the Gateway and its RFID controllers

 EMS’ HMS-Series, LRP-Series or T-Series RFID tags

1.5.2 Installation Precautions

 Route cables away from motors, solenoids, unshielded cables and any wiring

that carries high voltage or high current.

 Review the power requirements of your RFID network and provide a suitable

power supply.

 The Gateway is designed to withstand 8kV of direct electro-static discharge

(ESD) and 15kV of air gap discharge. However, it is not uncommon for some

applications to generate considerably higher ESD levels. Always use

adequate ESD prevention measures to dissipate potentially high voltages.

 Avoid mounting the Gateway or its RFID controllers near sources of EMI

(electro-magnetic interference) or near devices that generate high ESD

levels.

 Perform a test phase by constructing a small scale, independent network that

includes only the essential devices required to test your RFID application

(use EMS approved Subnet16 cables and accessories).

 Cables should only cross at perpendicular intersections.

1.5.3 Network & Power Considerations

• Refer to the network diagrams in Appendix C. Choose the network

architecture (ThickNet vs. ThinNet) that best suits your RFID requirements.

• Construct your chosen network using only EMS approved Subnet16 cables,

Drop-T connectors, Terminating Resistors and accessories.

• Review the power requirements of your RFID network and provide a suitable

power supply. (See Appendix B

for power supplies offered by EMS).

IMPORTANT NOTE: It is strongly recommended that power be applied directly to the

Subnet16

Network trunk and distributed through drop cables to the Gateway and

RFID controllers.
