Introduction
Thank you for purchasing a StarTech.com Converge A/V Mini VGA over Cat5 UTP Extender and
Receiver. Providing a high resolution point to point digital signage solution, the extender sends
the video signal to a remote monitor / display or projector over standard 4 pair CAT5e UTP cable,
using RJ45 connectors and supports transmission distances of up to 90m (275ft).
The ST121UTPMINI is an out-of-box solution that includes both the local transmitter and remote
receiver. The receiver is compact enough to be tucked away behind the display in tight spaces
for any installation.

• Transmits VGA Video and Audio through one Cat5 cable
• Supports resolutions up 1920x1200 at 90m (275ft.)
• Pure hardware design, no software or drivers required

tuning image quality

Installation
Transmitter Unit
1. Attach the Transmitter unit to the VGA source’s VGA output connector.
2. If using audio, connect the 3.5mm audio cable to the audio output connector.
3. To power the Transmitter unit, connect the integrated USB cable to an available USB port on
the video source device.
4. To test the VGA signal to the Transmitter unit, turn on the VGA source and observe the LED
indicators. The Video Sync LED should light up solid, if a good video signal is detected.
Receiver Unit
1. Attach the Receiver unit to the display’s VGA input connector.
NOTE: If the display has a VGA input that makes directly attaching the Receiver unit
dicult, use an appropriate length VGA extension cable
(i.e. StarTech.com ID: MXT101HQ3).
2. If using audio, connect the 3.5mm audio cable to the display’s audio input, or separate audio
receiver/speaker system.
3. To power the Receiver unit, connect the included DC power adapter.
4. The Video Sync LED should start blinking, as no video source is connected to the Receiver
unit yet.
