If the reader is lighting up and continuity has been established, but nothing is being seen on the panel, it is time for a Wiegand Test.
Step 1. Turn the reader to Test Mode and set the 1st 3 switches on the SW1 bank of 8 to the “OFF” position.
Step 2. Power Cycle the reader.
Step 3. Create a short Jumper Wire (2-3 Inches).
Step 4. Land one end of the jumper wire in the “IN-1” termination port this end stays for the duration of the testing.
Step 5. Next, connect the other end to the “0-1” location. When connected, the Input 1 LED should blink if properly sending Wiegand
Step 6. Move the “0-1” location to the “0-2” Location. When connected, the Input 1 LED should blink 2x and pause, and then repeat.
Step 7. Move the “0-2” to the “0-3” location. When connected, the Input 1 LED should blink 3x and pause and then repeat.
Step 8. If the reader functions as stated, the Wiegand is being sent properly. Remove and rewire the D-0 and D1 Wires
Step 9. Reset the 1st 3 dipswitches to their prior settings and power cycle the reader
If the Wiegand is out in one of the ports, the INPUT 1 LED will stay lit without blinking or not light up at all. If any of the Wiegand outputs are bad, a new mainboard is needed.
