Electrical Installation
RS 232:
Via the serial PC RS232 interface the DS400 amplifier is programmed and operated for the
start-up.
The software is described in the DS software manual.
The DSxx (D connector X10) and the serial interface (COM1/COM2) of the pc must only be
connected using a null modem cable.
Do not use a null modem link cable!
Install the cable only after disconnecting the device from the mains.
The interface is hard-coded to
115200
Baud.
In case of strong interferences at the
interface a line filter should be
installed.
Notebooks with a USB-RS232
converter are usually susceptible to
interference.
