VP-81SIDN - Connecting the VP-81SIDN 8x1 Digital Step-In Switcher

6.3 Connecting to the VP-81SIDN 8x1 Digital Step-In Switcher via RS-232

You can connect to the VP-81SIDN via an RS-232 connection using, for example,

a PC.

To connect to the VP-81SIDN via RS-232:

 Connect the Control RS-232 3-pin, terminal block connector on the rear

panel of the VP-81SIDN unit via a 3-wire cable (pin TX to pin 2, RX to pin 3,

and G to pin 5) to the RS-232 9-pin D-sub port on your PC

6.4 Connecting to the VP-81SIDN via RS-485

You can operate the VP-81SIDN via 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-81SIDN:

1. Connect the TxD+ 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-81SID.

2. Connect the TxD– 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-81SIDN.

3. If shielded TP cable is used, connect the shield to the G (ground) pin on the

unit.

6.4.1 Connecting and Controlling Multiple VP-81SIDN Devices

You can connect up to four VP-81SIDN devices with operation via RS-232 (as

shown in the example in Figure 6) or Ethernet. Connecting four devices provides

37 inputs.
