CHAPTER 3: Configuration

S2-1: Carrier Control Method

The setting for S2-1 determines whether the carrier is “Constantly On” or “Controlled by RTS.” This allows for operation in switched carrier, multipoint, and/or hardware handshaking applications.

S2-1	Setting
On	Controlled by RTS
Off	Constantly On

NOTE

When in Controlled mode, RTS must go negative to turn off the Transmitter and enable the Receiver.

S2-2: RTS/CTS Delay

The setting for switch S2-2 determines the amount of delay between the time the Converter “sees” RTS and when it sends CTS.

NOTE

The RTS/CTS Delay setting should be based upon transmission timing.

S2-2	Setting
On	8 msec
Off	No delay
