3.8 Serial Console Port: (JP1)
Serial console port is used for locally accessing Matrix-505 system using RS-232 port. The console
port is located inside the box and close to battery. It is a four-pin wafer box header. User can order
wafer console cable to access the serial console port.
Port 0: RS-232: RXD, TXD, GND
Therefore you need to open the upper metal case and prepare or purchase a serial console cable to
use the serial console port.
Another way to use serial console port is to assign any one of the four external serial ports (ttyS1 to
ttyS4) to be console port by command
setconsole.
