(3900ft) using a PC equipped with a card that provides an RS-485 port.

To connect a PC or controller to the RS-485 port on the unit:

1. Wire the RS-485 port on the VP-88K to the RS-485 port on the controller as

follows:

 Connect the A (+) pin on the RS-485 port of the PC to the A (+) pin on

the RS-485 port on the rear panel of the VP-88K

 Connect the B (–) pin on the RS-485 port of the PC to the B (–) pin on the

RS-485 port on the rear panel of the VP-88K

 Connect the G pin on the RS-485 port of the PC to the G pin on the

RS-485 port on the rear panel of the VP-88K

2. Set the DIP-switches (see

Section 6.5

3. Terminate the RS-485 line on both the VP-88K (set DIP-switch 1 to ON) and

on the controller.

) so that the Machine number on the

VP-88K is any number between 2 and 16.

6.4 Connecting to the VP-88K via the Ethernet Port
