Pin Name 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
Symbol 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.
