RC-76M/ RC-712M - Installing the RC-76M/RC-712M

4.2.1.2 Connecting RS-485 Devices

You can control up to one AV device by connecting it to the RC-76M/RC-712M via

its RS-485 connection.

To connect a device to the RC-76M/RC-712M via RS-485:

 Connect the A (+) pin of the device to the A pin on the RS-485 terminal block

of the RC-76M/RC-712M

 Connect the B (-) pin of the device to the B pin on the RS-485 terminal block of

the RC-76M/RC-712M

 Connect the G pin of the device to the GND pin on the RS-485 terminal block

of the RC-76M/RC-712MRC-76M

If your device is the first or last device on the line, slide the RS-485 termination

switch up, otherwise make sure it is set to down (see Figure 1).

4.3 Connecting the Ethernet Port

The Ethernet connection of the RC-76M/RC-712M lets you perform all control

functions of the RC-76M/RC-712M over the Internet using a PC running the

Kramer Site-CTRL control program to control AV devices.

To connect the RC-76M/RC-712M to a network:

1. Connect the Ethernet port of the RC-76M/RC-712M to the Ethernet port on a

network hub or network router, via a straight cable with RJ-45 connectors.

2. At the other end, connect the Internet to a PC running Site-CTRL.

3. After connecting the Ethernet port, you have to install and configure it. For

detailed instructions on how to install and configure your Ethernet port, see

the K-Config Software Guide.
