Appendix D
RS-422/ RS-485
Interface
This Appendix describes the EtherPath's 4-2843
RS-422/485 interface. This interface option may
be jumper configured in the field or pre-configured
at the factory.
Introduction
The 9-pin serial connector on the EtherPath may be for either RS-
232 or RS-422 (4-wire RS-485 point-to-point) operation using
internal jumpers.
Changing the Setting
Remove the main board from the case by removing two screws from
the rear panel. There is a row of jumpers and three rows of pins
adjacent to the serial connector.
RS-232 Setting
ALL jumpers should be placed in the positions nearest the board
edge.
