Handshaking Control
The data interface consists of an RS-232 port designed to operate either with
or without the hardware handshaking lines,
Request to Send
(RTS), and
Clear to
Send
(CTS). Handshaking Control includes the following options:
• RTS — RTS is asserted during transmissions. CTS is ignored.
• RTS/CTS — RTS is asserted during transmissions. CTS gates transmis-
sions.
• RTS/XON/XOFF — RTS is asserted during transmissions. CTS is ignored.
XON and XOFF gate transmissions.
• RTS On/CTS — RTS is always asserted. CTS gates transmissions.
• RTS/CTS Scan Control — RTS is asserted during transmissions. CTS gates
transmissions and controls enable and disable state of reader.
Handshaking Control = RTS
Handshaking Control = RTS/CTS
Handshaking Control = RTS/XON/XOFF
Handshaking Control = RTS On/CTS
Handshaking Control = RTS/CTS Scan Control
