C. SET RF SWITCH OPTIONS
1. Set Jumpers on the option card to the dotted position.
When setting the jumpers, observe that there are three pins on each header. The
jumper covers two of these pins and connects them together electrically. In one
position Pin 2 (center pin) is connected to Pin 1, while in the other position Pin 2 is
connected to Pin 3. Changing the jumpers changes the configuration of the circuit
board and how the board operates.
There is a dot on the board near either pin 1 or pin 3 of each jumper. Setting the
jumper so pin 2 is connected to this pin means the jumper is in the “dotted” position.
This indicates “Normal” operation of Wegener equipment.
All three of the jumpers on the RF Switch PWB should be in the “Dotted”
position.
D. RE-INSTALLING THE UNIT
1. Replace the cover and re-install the screws holding it in place. As with the RF
Switch, tighten the screws but do not overtighten.
2. Connect the “Output” connector of the RF Switch with the “RF Input” connector of
the receiver it is installed in with the supplied F-F coax cable. Tighten the F-
connector “finger tight.” See the Caution below.
3. Install the unit into the equipment rack, following the cautions and instructions in its
user manual. Re-install the cables as they were when the unit was removed from the
rack, with the exception in Step # D2.
4. Connect the desired RF inputs to the “F” connectors on the RF Switch. Again,
observe the caution regarding the force required to tighten these connectors.
Normally, the RF Inputs are configured according to instructions from the Network
Control, or Uplink. They will need to know which input is connected to which
connector so they can intelligently control program content.
E. OPERATION
To set up and operate a receiver with the RF Switch installed, consult the owner’s manual
for that unit. See the “Terminal Commands” or “On Screen Display” section for setup
and control.
* * * WARNING * * *
When connecting cables to “F” type connectors apply a force of no more than 12 inch lb.
(Finger tight). Avoid connecting adapters directly to “F” type connectors. Use at minimum
a 1-foot flexible extension cable between “F” type connectors and adapters.
