7: Configuring and Using External Devices
Using the Harris Automation ADC100 Automation Controller with the SGI Media Server
An ADC100 Harris Automation controller is connected to the SGI Media Server using
one or two serial ports per the video port to be controlled. If you want to play and record
at the same time, two serial port connections are required, unless you are using VDCP
multiport command support.
Follow these steps to connect and configure an ADC100 Harris Automation controller:
1. Cable the automation controller to the SGI Media Server. For more information
about cabling an RS-442 device to the SGI Media Server, see “RS-232 and RS-422
Cabling” on page 99.
2. Configure the automation controller. The information in Table 7-2 specifies how to
configure a Harris Automation ADC100 to control the SGI Media Server. If you are
using another automation controller that uses VDCP, you might need to configure
that controller in a similar way.
Configure each communications port that controls one or more video ports to use
the standard VDCP.
