Controls, Indicators, and Jumpers Chapter 3: EDH-6800-2 EDH Detection/Insertion Serial Distribution Amplifier Module
FR_ID On/Off Selects between external 9000SSN Frame ID or fault
opto-isolated output.
When set to On, EDH-6800-2 will attempt to read the
Frame ID from the 9000SSN silicon serial number device at
the FR-680X series frame RJ11 connector. When set to Off,
the EDH-6800-2 will use the RJ11 connector for the fault
reporting output (see page 32.) When both jumpers are
removed, the EDH-6800-2 is isolated from the RJ11
connector. If EDH-6800-2 does not detect the 9000SSN
device (if none is present at the RJ11 or if FR-ID is Off),
EDH-6800-2 will attempt to use the dual hex Frame ID
switches (SW4 and SW5) to determine Frame ID.
Jumper Description
Both jumpers (J5 and J8) must
be configured identically. And
all EDH-6800-2 (and similar)
modules in the same frame
must be configured identically
(FR-ID On or Off).
