RTS Protocol
The RTS output from the scanner may be pro-
grammed to operate in one of three different modes.
1. In the default mode, RTS signals when the
scanner is ready to receive commands or data.
2. RTS is in a fixed state.
3. RTS signals when the scanner has data to
transmit.
The RTS modes are independent of the CTS protocol.
However, you must select the same active state for
RTS as for CTS. You may not select CTS(–) and
RTS fixed high. If CTS(–) is selected, then the active
state for RTS will be low.
Scan the appropriate protocol option.
