AutoEQ Backchannel Setup
Introduction
To support remote equalization with the AutoEQ system, the equalization data is
transported over TCP/IP using a backchannel protocol. Before setting up the
backchannel, perform the TCP/IP Ethernet setup as outlined in the TCP/IP Ethernet Setup
section of the user manual. This document is to be used only as a guideline for setting up
the backchannel menus. Contact the Network administrator for proper guidance and
support to ensure setup is successful.
Backchannel Configuration
Using the Front Panel display and arrow keys, scroll thru the System menu until the
Backchannel sub menu is displayed. Both the local unit (the Modulator) and the remote
unit (with the AutoEQ card installed) require the proper configuration with the correct
network settings.
Refer to Figure 3.
Note: The router/gateway/firewall system must be configured to allow these ports to
pass on each communication end. Contact your Network Administrator for allowable
port numbers and to open up the ports on the firewall if necessary.
Enter into the Backchannel menu and the following sub menus will appear, however the
order may vary.
LOCAL PORT:
{XXXX}
The local port number must be set to the same value at
both the local and remote sites.
SERVER PORT:
{XXXX}
The server port number must be set to the same value at
both the local and remote sites.
Note: The local port and server port values must be different from the local and remote
sites.
SERVER IP ADDR:
{XXX.XXX.XXX.XXX} Hexidecimal Address
{ddd.ddd.ddd.ddd} Decimal Address
On the local unit, this should have the value of the
remote unit’s IP address.
Note: If the remote IP address is not publicly accessible then its translated NAT
(Network Address Translation) needs to be applied.
RECEIVE TIMEOUT:
{X.X MINUTES}
This value is factory set, and should only be adjusted as directed by your Network
administrator or Radyne Customer Service.
REPLY TIMEOUT:
{XX secs}
This value is factory set, and should only be adjusted as directed by your Network
administrator or Radyne Customer Service.
