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.
