TECHNICAL DESCRIPTION
4.2.2. Configuring the Router for a DARS Reference
The REF/DARS BNC can be configured as either a high impedance loop through from the REF BNC
(factory default) or as a 75 ohm terminated DARS reference input.
To reconfigure this BNC for a DARS input it is necessary to disconnect the power from the router and
remove the top cover. Jumper J19 controls whether the BNC will be a loop through or a DARS reference
input. Position jumper J19 in the
Loop
position (pins 2 & 3) for loop through operation. Position jumper
J19 in the
Split
position (pins 1 & 2) for DARS operation. In addition, you should also set the termination
jumpers for the REF and REF/DARS input BNCs to the 75 ohm position. Position jumper J20 in the
75
position to terminate the REF input BNC. Position jumper J12 in the
75
position to terminate the
REF/DARS input BNC.

UPGRADING FIRMWARE
The X0401 series routers contain firmware that is contained in a FLASH EPROM device. From time to
time firmware updates will be provided to add additional features to the unit.
You will need the following equipment in order to update the X0401 Router Firmware:
•
PC with available communications port. The communication speed is 57600 baud, therefore a 486 PC
or better with a 16550 UART based communications port is recommended.
•
“Straight-thru” serial extension cable (DB9 female to DB9 male) or (DB25 female to DB9 male).
•
Terminal program that is capable of Xmodem file transfer protocol (such as HyperTerminal).
•
New firmware supplied by Evertz.
4.3.1. Step 1 – Terminal Program Setup
1. If the REMOTE CTL connector is configured as a standard RS-232 DCE port (default from the factory)
connect a ‘straight-through’ serial cable to the REMOTE CTL DB9 connector on the rear panel.
If the REMOTE CTL connector has been configured as an RS-422 tributary port, (as described in
section 2.1.7) it can be automatically reconfigured as an RS-232 port with a non-standard pinout by
grounding pin 5. You will need to connect a special serial cable as shown in Table 4-1 to the
REMOTE CTL DB9 connector on the rear panel. This cable will automatically change the port to
RS-232 levels.
