Scanner Specifications

Any scanner connected to an XL200 series controller must conform to the following communication
specifications:

Baud Rate: 9600

Stop Bits: 1

Parity: None

Data Bits: 8

Suffix: None (some scanners append a carriage return at the end of every scan by default)

DB9 Port

The DB9 port on the top of the XL200 controller has three uses:

Scanner port

Debug port

Flash memory port

DB9 Port Pinout

2 RS232 TX
3 RS232 RX
5 GND
7 RS232 CTS
8 RS232 RTS
Pin 7
Pin 7 of the DB9 port is the Clear-to-Send input on the controller.
A pull up resistor on that input keeps it high. In some RS232 applications, this input is toggled by the
outside device's Request-to-Send (called handshaking).
The XL200 controller does no handshaking, with either hardware or software, so it doesn't use pin 7
when communicating with other devices. However, a laptop connected to that port usually pulls pin 7
"low," which informs the controller to set up the port for a debug/flash.
