SWITCHER TROUBLESHOOTING GUIDE Cause 2: 8 We have carefully tested and have found no problems in the supplied SW1956CT unit. However, we would like to offer the following suggestions: Solution 1: Remove the input signals from the switcher. If the IN 2 LED is off, call ALTINEX at (714) 990-2300. If the IN 2 LED is on, see Solution 2. 8.1 POWER LED IS OFF Cause 1: Solution 2: Connect a properly formatted signal from an ALTINEX Twisted Pair transmitter to INPUT 1.
SWITCHER Solution 3: Bypass the switcher and connect the output of the transmitter directly to the input of the receiver. If the display is good, then call ALTINEX at (714) 990-2300. If there is still no display, see Cause 4. ALTINEX POLICIES Cause 4: Cable connections are incorrect. 9.2 CONTACT INFORMATION Solution: Make sure that cables are properly connected.
