4.4 Configuring for Input Signal and Impedance

4.4 Configuring for Input Signal and Impedance

The Input Signal and Impedance settings are configured at the factory for a modulated input and low Z input and output impedance. If the signal sources have a high Z output impedance, then

Caution

When opening the top cover and changing the power supply settings, use proper ESD precautions. This includes ensuring that you are properly grounded before touching the internal PWA of the unit to change the jumper settings.

Required for this procedure:

#1 Phillips screwdriver

To change the jumper settings:

1.Disconnect both power supplies from their power source.

2.Using a #1 Phillips screwdriver, remove the top cover.

3.Move the jumper one position to the left to the 2S position.

4.Replace the top cover.

5.Reconnect the power supplies.

Gain setting for selected input impedance. Must follow Input impedance.

Inputs A & B impedance jumpers configured for the LO-Z (50 Ω).

Signal Type jumper configured for modulated (IRIG-B).

4.5 Configuring for Dual Power Supplies

The power supply setting is configured at the factory based upon single or dual power supply configuration. If you are adding a second power supply to a unit that was originally configured for a single power supply, you should change the internal jumper setting. The jumper setting ensures that the power supply LEDs reflect the proper configuration and that the second power supply is monitored.
