What is the input impedance for the ION 8600 IRIG-B connection?

Issue
What is the input impedance for the ION 8600 IRIG-B connection?

Product Line
ION 8600 series meters

Cause
Customer would like to Synchronize their ION Meters via GPS. In such a case, it is possible to only have a limited number of devices (like ION meters and Relays) on a single clock because the impedance of too many devise in series will impact the clock signal.

Environment
Configuring the ION 8600 meters to do Time Sync.

Resolution
The input impedance for the IRIG-B input on the ION8600 is 425 k ohms at 5V DC.
