Pin Name Type* Function
1Trigger I Signals scanner to begin scanning session.
2TXD OSerial 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. Used as a clock by a Symbol
Synapse host. Pin is shorted to RTS/SYN_DAT in USB cables to
allow for auto-detection of USB mode via signal loopback.
5Ground Power supply ground input and signal ground reference.
6Power 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.
