6.6Connecting to the VP-81KSi via the RS-485 Port

You can operate the VP-81KSivia the RS-485 port from a distance of up to

1200m (3900ft) using any device equipped with an RS-485 port (for example, a PC). For successful communication, you must set the RS-485 machine number and bus termination.

To connect a device with a RS-485 port to the VP-81KSi:

•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-81KSi

•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-81KSi

•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-81KSi

6.6.1Setting the RS-485 Machine Number and Bus Termination DIP-switches

This section describes the VP-81KSiDIP-switch settings that determine the RS-485 machine number and bus termination.

Figure 8 illustrates the factory default DIP-switch positions.

DIP-switch Number

Function

1, 2, 3

Machine number (see Table 4)

 

Default—All off (up), machine number 1

4

RS-485 Bus Termination

 

Default—Off (up)

DIP-switches 1, 2 and 3 determine the RS-485 machine number of the VP-81KSi. When several VP-81KSiunits are connected, the machine number determines the unique identity of the VP-81KSion the bus (see Table 4).

Note:

•When using a stand-alone VP-81KSiunit, set the machine number to 1 (factory default)

•When connecting more than one VP-81KSi, set the first machine (connected via RS-232) to be machine number 1. The other VP-81KSiunits must each be set to a unique machine number between 2 and 16
