Data (Network) Connections; Device Control Connections And Configuration - Extron electronics HC 404 User Manual

5. Check the LEDs at the Out and In interconnection ports.
If the Signal LED for the Out port on the transmitter is not lit, the selected
•
transmitter input (2, 3, or 4) has no active signal.
If the Signal LED for the In port on the receiver is not lit, the receiver does not detect
•
a valid signal coming from the selected input on the transmitter.
•
•
•
If the Link LED at the Out and In ports is not lit, the units do not have a valid
•
interconnection link. Ensure that the interconnection cable is firmly connected at
both ends and is correctly wired.
6. Verify that the EDID settings are correct. Use the EDID Minder feature within the PCS
software to adjust the settings, if needed.

Data (Network) Connections

1.
Check the cabling connections and make adjustments as needed. The Link LEDs on
the HCR 102 receiver and on the PC should be lit solid green if a network connection is
detected. If these LEDs are not lit, the following items are possible causes:
The cable is faulty or not plugged in.
•
The wrong type of cable is being used (see
•
page 18).
2. Try to "ping" the unit by entering ping 192.168.254.250 at the command prompt
on the PC, or use 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 unit.
3. If contact is established with the unit, but the HCR 102 web pages cannot be accessed
by your browser program, verify (via an Internet network options or preferences menu,
or your IT department) that your browser is configured for direct network connection
and is not set up to use a proxy server.

Device Control Connections and Configuration

• Verify that ports are wired correctly and that ground (earthing) wires are connected to
the proper pins on the HCR 102 and, if applicable, on the controlled device.
• Ensure that each IR emitter head is placed adjacent to or directly over the IR pickup
window on the controlled device.
• Verify that the appropriate drivers were used while creating the configuration file and that
the correct commands and signal types (IR, RS-232, Ethernet) are associated with the
appropriate ports on the HCR 102 and on the other devices.
Ensure that the transmitter-receiver interconnection is wired correctly (see
Transmitter-Receiver Interconnection
Ensure that the transmitter has a valid AV signal at the selected input (see
Signal LEDs on page 8, and check the connections and configurations of
the input devices).
If firmware was recently updated, the unit may require a reset in order to re-
establish communication between transmitter and receiver.
