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.
