Function Switch Three

Function switch three is a six-segment DIP switch used to configure the data interfaces for each channel.

Set to Up (DTE) if the channel is connected to a DTE-type device such as a CPU port or a terminal (this configures the 2185 interface as Data Circuit-terminating Equipment - DCE).

Set down (DCE) if the channel is connected to a DCE-type device such as a modem (this configures the 2185 interface as Data Terminal Equip- ment - DTE).
