Stop Bits and Character Length
The Stop Bits and Character Length parameter contains four selections: 1 Stop Bit and 7-bit
Character Length, 1 Stop Bit and 8-bit Character Length, 2 Stop Bits and 7-bit Character
Length, and 2 Stop Bits and 8-bit Character Length. Choosing no parity and 7-bit Character
Length causes the 7893 to send two (2) stop bits; the scanner must also receive two (2) stop
bits. If 8-bit Character length and parity is selected, only one (1) stop bit is sent. Scan the
appropriate
Hex 0 through Hex 3 tag to set the Stop Bits and Character Length.
Handshake
The Handshake parameter contains six selections. When considering these, note that the
scanner controls only RTS; however, it can monitor CTS. The following list identifies each
Handshake option.

RTS is always low, CTS is ignored ( Hex 0 tag).

RTS is always high, CTS is ignored ( Hex 1 tag).

Scanner raises RTS and waits for CTS to go high before transmitting ( Hex 2 tag).

Scanner raises RTS before transmitting and ignores the state of CTS ( Hex 3 tag).

RTS is always low and scanner waits for CTS to go high before transmitting ( Hex 4 tag).

RTS is always high and scanner waits for CTS to go high before transmitting ( Hex 5 tag).
Scan the appropriate Hex 0 through Hex 5 tag to set the Handshake option.
