Connecting the Power Supply
Reader R95 Installation and Connections 2-7
Complete the following steps:
1. Unplug terminal blocks TB4 and TB6 from connectors TB3 and TB5 respectively.
2. Run the RS-485 incoming and outcoming cables through the cable grips into the
Readers enclosure.
3. Connect the four-wire communication line to the corresponding pins A1, B1, A2,
and B2 on terminal block TB4 (or TB6). Connect the cable shield to the pin
marked G on terminal block TB4 (or TB6).
Caution Before installing the RFID System, label the two wires of one line of RS-485 as A1 and
B1, and the other two wires of RS-485 as A2 and B2. Keep this naming convention for
all connections made on this RS-485 communication line.
4. Set the RS-485 communication line terminating load for each two-wire line. The
ends of a multidrop network line can be easily identified, because only one RS-485
cable is connected to that equipment. To connect an 100 ohm terminating load on
each separate RS-485 line, place jumper P1 between pins 1-2 of J1, and jumper P2
between pins 1-2 of J2. For any other equipment connected to this RS-485
communication line, place jumpers P1 between pins 2-3 of J1, and P2 between
pins2-3ofJ2respectively.
5. Plug terminal blocks TB4 and TB6 into connectors TB3 and TB5 respectively.
Connecting the Power Supply
The Reader R95 requires a 12Vac or 13 to 16Vdc power source, and a maximum
current of 0.3A. For more information on the Reader, see Appendix A, Specifications.
The power supply connector is located on the Motherboard MBD95. The MBD95 is the
bottom board of the Reader Module Assembly (P/N 500048).
Notes 1. To connect the power supply, use electrical wire gauge 16 AWG (minimum).
2. The main ground connection of the Reader is on the power supply connector. It is
indicated by the ground symbol. Use an electrical wire with at least gauge 16AWG
for the main ground connection.
3. We recommend using Lyngsoe’s Power Supply, model TRM95/120V or TRM95/
230V, as required by the local AC power line voltage.
