4 Serial Port Connectivity
Many devices (PTZ keyboards, PTZ cameras, etc.) use RS-422/485 protocols for
communicating with other equipment. These protocols are standards for binary data exchange
between DTE and DCE equipments.
To connect serial equipment to an ION-R100 using RS-422/485 4-wire configuration, use the
following steps:
1. Connect twisted pair cables to the
Terminal Bloc Socket
located on the front panel of the
device. Connect to

2. Select the desired operation mode (RS-422 4-wire, RS-485 2-wire or RS-485 4-wire)
using the devices web interface or external VMS interface.
3. To ensure proper connection between RS-422 4-wire or RS-485 4-wire serial equipment
and the ION-R100, use the following scheme:
