Handling cables

Notes about handling cables

* Cables and connectors are not included with the products.

Notes on cables

• Use PE (polyethylene)-insulated PVC jacketed cable.
  Parallel or jacketed conductors, mid-capacitance, non-shielded cable is recommended.
• Never use twisted pair cable or coaxial cable.

■ How to connect or disconnect stranded wires.

- To ensure that the wire won't bend, press the release button while inserting into terminal.

e.g.) NIM-40B

e.g.) NI-BA

■ Note about wire-to-wire connection.

Make wire-to-wire connections securely as shown below.

Connection wiring diagram (details)

Connecting to the master station

Procedure

1 Detach the terminal cover by removing the two screws.

2 Connect the wiring from the sub stations and power supply to the master station by inserting lead wires to the corresponding terminals.

Using the cable tie is recommended for secure installation.

3 After the connections for the whole system have been completed, turn on the power switch.

The power indicator on the operation panel lights up.

4 Attach the terminal cover with the two screws.

■ Note about connecting a PC to the master station.

Use the included RS232C cable for the connection.

* Install NI-SOFT on the PC from the included CD-ROM. Refer to the instruction manual for NI-SOFT for details.

* When extending the RS232C cable, the distance between the master station and the PC should be 15m (50') or less.

CAUTION

■ Note about connecting the power supply unit(s) to the master station.

* When using the master station, 60-call or 80-call, two power supply units are needed.
