INTERFACING TO COMPUTERS WITH BNC OUTPUTS
The IN5129A, IN5132A, and IN5133A are special input cables designed for use with workstations and terminals which have BNC video outputs. The chart below describes the input signal compatibility for each of these cables:

Installation Procedure - IN5129A / IN5133A
The video signal input to the IN2000 / IN2001 must be terminated into 75 ohms for proper image display. In order to achieve this termination the following installation procedure should be followed:
1. Attach a BNC "T" (1 male, 2 female) to each BNC output connector on the computer.
2. Connect the IN5129A or IN5133A cable to one side of the "T" connectors.
3. Connect the local monitor to the other side of the "T" connectors. If no local monitor is present, use a 75 ohm Male BNC termination plug on the Red, Green, and Blue connectors (TTL sync signals do not require a 75 Ohm terminator).
Installation Procedure - IN5132A
The IN5132A should be connected directly to the computer’s monochrome composite video output. This cable includes an internal 75 ohm termination so the signal should not be split off to a local monitor before feeding it into the IN5132A or a double termination will result. If a local monitor is required, use one of the following methods to split the signal:
Looping Method - If the local monitor has a "Loop Out" connector, connect the monitor directly to the computer video output. Turn the Loop Out termination switch to "75 ohm termination OFF" and connect the IN5132A to the monitor’s Loop Out connector. Distribution Amplifier - use a high resolution distribution amplifier such as the IN2055 to split the signal between the local monitor and the IN5132A / IN2000.
