The DA1921SX has two outputs with 15-pin HD female connectors. It allows the distribution of video signals to two monitors. With equalization, the DA1921SX receives signals through a CAT-5 cable from as far as 500 feet away. PIN No. 1 2 3 4 5 6 7 8 Input Signals RJ-45 Connector RR+ GBB+ G+ HORHOR+ PIN No.
DISTRIBUTION AMPLIFIERS INSTALLING YOUR DA1921SX 7.1 LED INDICATOR 6 The DA1921SX offers a special LED on the front panel that provides feedback to the user. When power is connected to the DA1921SX, the LED will turn Red. When a valid CAT5 source is connected to the DA1921SX, the LED will turn Green, indicating that it is receiving a signal by sensing the presence of the sync portion of the signal. Step 1. Connect the 9V 500mA AC adapter’s output plug to the DA1921SX’s power input connector - 2.
DISTRIBUTION AMPLIFIERS Cause 3: The DA1921SX has a problem. Solution: If there is AC power to the adapter and the LED still does not turn on, the DA1921SX or the power adapter may require service. Call ALTINEX at (714) 990-2300. In general, cable runs less then 50 feet require little or no video equalization and should be set to minimum. Longer cable runs will require equalization on both the transmitter and receiver. 8.4 REMOTE IMAGE QUALITY IS POOR 8.2 LED IS NOT GREEN Cause 1: There is no power.
