1.5 INSTALLATION GUIDELINES

1.5.1 Hardware Requirements

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

 One Subnet16 Profibus Gateway Interface Module

 One Profibus-capable host; Programmable Logic Controller (PLC) or PC

 One to 16 RFID controllers (Cobalt C-Series, HF-Series or UHF-Series Controllers -

RS485 models)

 Adequate length cabling, connectors and terminators

 Sufficient power, supplied via Subnet16 network cabling, capable of powering the

Gateway and its RFID controllers

 Datalogic Automation RFID series tags: HMS, LRP, T/Gamma, I, or UHF-G2-525

1.5.2 Installation Precautions

 Do not route cables near unshielded cables or near wiring carrying high voltage or

high current. Cross cables at perpendicular intersections and avoid routing cables

near motors and solenoids.

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

supply.

 Avoid mounting the controller near sources of EMI (electro-magnetic interference) or

near devices that generate high ESD (electro-static discharge) levels. Always use

adequate ESD prevention measures to dissipate potentially high voltages.

 If electrical interference is encountered (as indicated by a significant reduction in

read/write performance), relocate the controller to an area free from potential sources

of interference.

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

includes only the essential devices required to test your RFID application (use

Datalogic Automation approved Subnet16™ cables and accessories).

1.5.3 Network & Power Considerations

 Refer to the network diagrams in Appendix B. Choose the network architecture

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

 Construct your chosen network using only Datalogic Automation 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 A for power supplies offered by Datalogic Automation).

NOTE

It is recommended that power be 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

(see examples), you can limit voltage drop at the ends.

GETTING STARTED

1.5.4 Maximum Supported Trunk and Drop Cable Lengths

 ThickNet trunk length up to 300 m.

 ThinNet trunk length up to 20 m.

 ThinNet drop cable length up to 2 m.

1.6 INSTALLING THE GATEWAY

The numbered steps in the following procedure are also indicated in the SubNet16 networks

example layouts shown in Appendix B.

1. Preliminary Notes: Read the Installation Guidelines in par. 1.5.

2. Mounting: Mount the Gateway to your chosen location using two M5 (#10) screws,

lock washers and nuts. The Gateway may be mounted in any orientation, but should

be aligned in such a manner that the LED indicators can be seen during operation.

3. Gateway Connection: Attach one end of a 5-pin, male-to-male, M12, ThinNet drop

cable (P/N: CBL-1481-XX) to the 5-pin, female, M12 connector on the Gateway.

Connect the other end of this 5-pin, male-to-male, M12, ThinNet drop cable to the 5-

pin, female, M12 connector on EITHER a ThickNet to ThinNet Drop-T Connector

OR a ThinNet to ThinNet Drop-T Connector (as per your network and RFID

application requirements).

4. Trunk Wiring: Attach one end of a male-to-female trunk cable to each mating

connector on the Drop-T Connector. Continue connecting trunk cables and Drop-T

connectors as needed.

Note: trunk length should not exceed 300 m for ThickNet and 20 m for ThinNet.

5. RFID Controller Connection: Connect the male end of a 5-pin, male-to-female,

ThinNet drop cable to the female end on your Drop-T connector(s). Attach the

remaining female end of the ThinNet drop cable to the 5-pin, male, M12 connector on

a Cobalt UHF, Cobalt HF or C-Series Controller (RS485 models). Repeat Step 5

for each RFID controller you plan to install.

Note: maximum drop cable length is 2 m.

6. Termination Resistors: For ThickNet Networks: Connect a Terminating Resistor

(P/N: CBL-1489, male) or (P/N: CBL-1497, female) to the first and last Drop-T

Connector on the trunk line.

For ThinNet Networks: Connect a Terminating Resistor (P/N: CBL-1490, male) or

(P/N: CBL-1496, female) to the first and last Drop-T Connector on the trunk line.

7. Power Supply Wiring: For ThickNet Networks: Using a 5-pin, female, 7/8 - 16,

ThickNet to Bare Wire Leads cable (P/N: CBL-1495-XX), connect the bare wires to

your power supply (SHIELD wire connected to Earth). Attach the female, ThickNet

end to the 5-pin, male, ThickNet end on a Drop-T connector (P/N: CBL-1526).

For ThinNet Networks: Using a 5-pin, female, M12, ThinNet to Bare Wire Leads cable

(P/N: CBL-1494-XX), connect the bare wires to your power supply (SHIELD wire

connected to Earth). Attach the female, ThinNet end to the 5-pin, male, ThinNet end

on a Drop-T connector (P/N: CBL-1486).

8. Host Connection: Connect the Gateway to the Profibus network via a Profibus-

compatible interface cable. Turn the power supply ON.

The POWER LED on the Gateway will remain lit while power is applied to the unit.

After the boot process is complete, the PBS Mode LED will also light up to indicate

the Gateway Profibus mode. It may appear green or red (solid or flashing) depending

on the status of the connection with your Profibus network (see par. 2.2 for the

behavior of the Gateway’s Profibus Mode LED).

9. Automatically Configure Subset16™ Node IDs: At this point all controllers are

powered and should have Node IDs set to 00, (all controller Node LEDs

= OFF), and

Subnet16™ baudrate = 9600 (factory defaults).

a. Place the RFID Controller Configuration Tag in front of an RFID Controller (the

controller's red RF Activity LED blinks once indicating the tag has been read), and

wait for the Gateway to assign a valid Node ID to it. The controller's Node LEDs

now indicate a valid Node ID. Remove the Configuration Tag from the controller.

b. Repeat this step for each node in the Subnet16™ network (one controller at a

time). The first is Node ID 1, then 2 and so on up to 16 (binary).

The Subnet16™ network is now configured with the default values and can communicate

with the Gateway Profibus which in turn communicates with the Master Profibus.
