SERVICING and TROUBLE SHOOTING (Continued)
3. Check for split pairs. A split pair cable will drop packets even if the cable is only 2 meters long. The incorrect wiring example
shown below represents a split pair.
4. Re-make the RJ45 connector. A marginal or corroded crimp will cause dropped packets.
5. Check the cable length. The Ethernet standard for unshielded twisted pair copper cables is a maximum 100 meters (330 feet).
Copper cables longer than this will not support CobraNet streaming audio.
Symptom: I can communicate with my Iconyx array, but I get errors when writing beams.
1. This is a classic symptom of network problems. Go to the Network Manager or start CobraNet Discovery and look at the error
count for all devices. Any device that shows errors has a suspect network connection. Review the previous page for
troubleshooting tips..
Symptom: Analog audio sounds like its gating.
1. You are sending a signal to Analog 1, but some other input is selected on the Connect tab. As an aid to troubleshooting the
Analog 1 input will always pass audio, but if some other input is selected, Analog 2 for example, the signal to Analog 1 must
exceed a threshold, this is why you hear it gating. Select Analog 1 as the input and the gating will stop.
Symptom: My Iconyx is slowly flashing the blue wink light.
1. You have the Ethernet cable plugged into a slave unit. Either move the cable to the master unit or set the unit with the cable to
be the master.
Symptom: My IC16-R, IC24-R, LC32-R or IC-Live Dual shows up as only a single IC8 or IC Live module.
1. Is the wink light flashing slowly? If so, you have the Ethernet cable plugged into a slave module. Either move the cable to the
master module or reset the DIP switches.
2. Check the DIP switches, there must be only one master and the slaves must be individually identified as slave modules.
3. Did you connect the interconnect cables between the modules and screw down the connectors? If not, you must do this.
CORRECT WIRING
Pins 1 & 2 = 1 pair
Pins 3 & 6 = 1 pair
Pins 4 & 5 = 1 pair
Pins 7 & 8 = 1 pair
INCORRECT WIRING (Split Pair)
Pins 1 & 2 = 1 pair
Pins 3 & 4 = 1 pair
Pins 5 & 6 = 1 pair
Pins 7 & 8 = 1 pair
