Network Button Panels • Software-Based Configuration and Control 32
Troubleshooting
Turn on the input devices (DVD players, Blu-ray players, PCs, and other sources), output
devices (display screens, projectors), the controller, and the PC. Push a front panel button or
(for US gang models) rotate the Volume knob.
If an input or output AV device cannot be remotely controlled (does not respond as
expected), check the following:
Power Connections
• Ensure that all devices are plugged in.
• Make sure that each device is receiving power. The front panel buttons light if the unit is
receiving power.
Data Connections
1. Check the cabling connections and make adjustments as needed. The Link LEDs on
the control processor or collaboration space receiver, the network button panels, and
on the PC should be lit green steadily if a network connection is detected. If these LEDs
are not lit, either the cable is faulty or not plugged in, or it is the wrong type of cable or is
miswired (see LAN (Ethernet) and PoE connector and LEDs on page15).
2. Try to “ping” each device by entering one of the following at the command prompt on
the PC:
• ping 192.168.254.250 — for a control processor or collaboration system
receiver without AVLAN, or for an IPCPPro control processor AVLAN port when
the DHCP server is disabled (default)
• ping 192.168.253.250 — for the LAN port of an IPCPPro control processor
with AVLAN
• ping 192.168.245.1 — for an IPCPPro control processor AVLAN port if the
DHCP server is enabled
• ping 192.168.254.253 — for an NBP button panel
Or ping the IP or web address provided to you by your system administrator.
If you get no response:
• Make sure your unit is using the appropriate subnet mask (check with your system
administrator).
• Make sure your PC and network do not have a software firewall program that might
block the IP address of the devices.
3. If contact is established with the unit, but the NBP internal web pages cannot be
accessed by your browser program, verify that your browser is configured for direct
network connection and is not set up to use a proxy server. Use the Internet network
options or preferences menu in the browser to check the settings.
Device Control Connections and Configuration
• Verify that ports are wired correctly and that ground (earthing) wires are connected
to the proper pins on the control processor or collaboration system receiver, and, if
applicable, on controlled devices.
• Verify that the NBP is grounded (see grounding instructions on page14).
• Verify that the appropriate drivers were used while creating the GC configuration file
and that the correct commands and signal types (IR or RS-232) are associated with the
appropriate ports on the control processor or collaboration system receiver and on the
other devices.
