Type*
Function
1
Trigger
I
Signals scanner to begin scanning session.
2
TXD
O
Serial data transmit output. Drives the serial data receive input on
the device communicating with the scanner.
3
RXD/D+
I/O
RS232 Mode
: Serial data receive input. Driven by the serial data
transmit output on the device communicating with the scanner.
USB Mode
: D+ signal. During USB operation this signal is pulled up
by a 1.5k Ohm resistor to begin USB enumeration. In this mode it is
a differential bi-directional signal.
4
SYN_CLK
I/O
Synapse Mode
: Synapse Clock line. Signal used as a clock by a
Synapse host. Pin is shorted to RTS/SYN_DAT in USB cables to
allow autodetection of USB mode via signal loopback.
5
Ground
Power supply ground input and signal ground reference.
6
Power
5.0 VDC ± 10%
7
CTS/D-
I/O
RS232 Mode
: Clear-to-send handshaking input line, used only in
conjunction with the RTS line. Optionally used by another device to
signal the scanner to begin transmitting data.
USB Mode
: D- signal. During USB operation this signal works in
conjunction with the D+ signal as a differential bi-directional signal.
8
RTS/SYN_DAT
I/O
RS232 Mode
: Request-to-send handshaking output line, used only
in conjunction with the CTS line. Optionally used by the scanner to
signal another device that data is available to send.
USB Mode
: Synapse Data line. Signal is used to transmit data to
and from a Synapse host.
9
Beeper/Download
I/O
During normal operation this signal functions as an external beeper
drive line. This signal can sink 50mA of current to drive an external
beeper, and is normally pulled up. This signal is also used to begin
Flash Download operation when grounded externally during power
up.
