Testing COM Function
3.1.4.
The ALTA DS 4K is equipped with a Mini USB 2.0 port that supports COM (TX/RX).
The first step is to connect the host machine to the ALTA DS 4K system through the Mini
USB 2.0 port. We suggest using the optional accessory Mini USB 2.0 to 9-pin D-SUB
cable (P/N: 99G33-192458). Next on the host machine start a serial communication
program such as Putty, GtkTerm or Minicom with the same serial port setting using the
appropriate serial device.
