Connecting the Multi-Drop Box to a Computer for RS-485 Communications

Connect the included serial cable (or another appropriate serial cable if the included

cable is too short) to the 9 pin D-SUB connector labeled "COM PORT". Connect the

other end to a valid serial port on your computer.

If you will be making your own cable, or you wish to run the RS-485 Input/Output off to

another device, you can bypass the 9 pin D-SUB connector and simply use the terminal

block on the front of the device.

To do this, you must;

1. Connect the RS-485 network "Signal +" to the "Sig +" on the terminal block,

2. Connect the RS-485 network "Signal –" to the "Sig –" on the terminal block,

3. Connect the RS-485 network "Ground" to the "Ground" on the terminal block,

For these devices, the power and signal grounds are common and will be connected to

the same socket on the terminal block.

Caution: Please note that while the RS-485 signals are present on the DB-9 port

and cable, there are no accepted industry standards for this interface. Please verify

pin-out capability before connecting.

To connect a wire to the terminal block:

1. Strip approximately 3/16 (0.312) of an inch of insulation from the end of the wire.

2. Turn the screw on the socket to which you will be attaching the wire counter-

clockwise.

3. Turn the screw until the socket is opened enough to fit the stripped end of the wire

into the socket.

4. Insert the wire into the open socket and gently turn the screw clockwise until it is

snug.

5. Visually inspect the connection to make sure the socket is closed on the conductive

part of the wire and not on the insulation.

6. Gently tug the wire to make sure it does not come out.
