Part 4: Troubleshooting
Note: It’s possible to have the channel names of the transmitter and receiver match, but not have the two devices linked. If you link a transmitter
and receiver via the IR sync, they will be linked. If you then turn the transmitter off and link a second transmitter to the receiver over the original link
in slot 1, the receiver will unlink the first transmitter from the ShowLink network, but the channel name of the first transmitter will not change once it’s
powered back on. In this case you’ll have two transmitters with the same channel name but only one will be linked to the receiver (the link icon will
indicate this on the receiver). Therefore, it’s good practice, when in doubt or when troubleshooting ShowLink problems, to re-link the transmitter and
receiver via the IR sync function on the receiver.
Check if the receiver can ‘see’ the ShowLink Access Point with FIND ALL
The network cable to the ShowLink access point must be securely plugged into a Power-Over- Ethernet (PoE) jack to
power the access point (unless an external DC power supply is used). The power and network LEDs on the ShowLink
access point should be on and the network LED should be blinking. Both the AXT400 receiver and AXT620 Ethernet
switch provide PoE network jacks to power the access point. Both network jacks on the AXT400 receiver provide PoE,
and number 5-8 network jacks on the AXT620 Ethernet switch also provide PoE. The AXT600 Spectrum Manager and
AXT630/631 Antenna Distribution Amplifier also provide PoE network power. The AXT900 Rack Charger does NOT
provide PoE network power.
Check the network cable to the ShowLink Access Point
The network cable to the ShowLink access point must be securely plugged into a Power-Over- Ethernet (PoE) jack to
power the access point (unless an external DC power supply is used). The power and network LEDs on the ShowLink
access point should be on and the network LED should be blinking. Both the AXT400 receiver and AXT620 Ethernet
switch provide PoE network jacks to power the access point. Both network jacks on the AXT400 receiver provide PoE,
and number 5-8 network jacks on the AXT620 Ethernet switch also provide PoE. The AXT600 Spectrum Manager and
AXT630/631 Antenna Distribution Amplifier also provide PoE network power. The AXT900 Rack Charger does NOT
provide PoE network power.
Check the IP address mode of the ShowLink Access Point
If the cable connections to the ShowLink access point are good, but the receiver cannot ‘see’ the access point using the
FIND ALL function, it’s possible the access point is configured for an IP address that’s not on the same IP subnet as the
receiver. You can do a factory reset of the ShowLink access point to ensure the IP mode is set to AUTOMATIC that will
request an IP address from the DHCP server that’s on the same subnet as the receiver. Press and hold the recessed
Reset button at the bottom of the access point for several seconds until all the LEDs turn on and then let go. The access
point will return to a factory default setting of IP mode = AUTOMATIC. After the access point reboots, wait a few seconds
and retry the FIND ALL function from the receiver. If the receiver can now ‘see’ the ShowLink access point, then the
transmitter that’s linked to the receiver should now be remote controllable via the ShowLink network.
Check the ShowLink antenna and connection
Ensure that the antenna is securely connected to the SMA jack of the ShowLink access point and that there is a good
line-of-sight path to the transmitter. Inspect the antenna connector for a damaged or missing center pin.
