3.3 Command Mode Interface
Set-Up Physical Interface Components
Hardware required:
• Service PC
• one free COM port on the Service PC
• special cable to connect DVD recorder to Service PC
The service PC must have a terminal emulation program
(e.g. OS2 WarpTerminal or Procomm) installed and must
have a free COM port (e.g. COM1). Activate the terminal
emulation program and check that the port settings for the
free COM port are: 19200 bps, 8 data bits, no parity, 1 stop
bit and no flow control. The free COM port must be
connected via a special cable to the RS232 port of the
DVD recorder. This special cable will also connect the test
pin, which is available on the connector, to ground (i.e.
activate test pin).
Code number of PC interface cable: 3122 785 90017
