Introduction The StarTech.com Converge A/V VGA over Cat5 Video Extender system is comprised of a transmitter unit (ST1214T) and a receiver unit (ST121R) and optionally a repeater unit (ST121EXT). This video extender system allows you to split and extend a single VGA source signal to up to four separate remote locations. The VGA signal is extended using standard Cat5 UTP cable, with a maximum distance of up to 150m (492ft) or 300m (984ft) with a repeater.

Installation NOTE: To prevent potential electrical damage to the units in some environments, ensure that the chassis is properly grounded. Hardware Installation The following instructions detail how ST1214T, ST121R and ST121EXT can be used to extend a VGA signal to remote displays, using a variety of different configurations. ST1214T (local) and ST121R (remote) 1.
The following diagram illustrates the connection between transmitter (ST1214T) and receiver (ST121R) units. ST121R Remote Displays Cat5 cables (150m max) ST1214T VGA cables VGA cable Video Source ST1214T (local), ST121EXT (extender) and ST121R (Remote) Using the ST1214T, you can split the VGA signal from the source into 4 separate VGA signals, for reception at remote locations.
5. Using a standard UTP cable with RJ45 terminators on each end, connect the Cat5 OUT port provided by the transmitter unit(ST1214T) to the Cat5 IN port provided by ST121EXT. 6. Connect the repeater unit (ST121EXT) to an available power outlet, using the adapter provided. 7. Optional: You can connect two monitors directly to the repeater. To do so, simply connect the monitors to the MONITOR OUT ports on the repeater unit. 8.
The following diagram illustrates the connection between transmitter (ST1214T) and receiver (ST121R) units, with the addition of a repeater unit (ST121EXT). Please note that although only one repeater is used in this illustration, up to four can be used simultaneously.
Signal Equalizer Selector (ST121R, ST121EXT) The Signal Equalizer Selector on the Receiver and Repeater Units can be adjusted to obtain the optimal video signal for various cable lengths. There are four settings on the selector switch, indicating cables of different lengths. The following table can be used as a reference for selecting the appropriate setting: Wiring Diagram The Video Extenders requires an unshielded twisted pair Cat5 cable no longer than 150m (492ft).
