6 PC Control of the Unit via RS-232 Interface
It is possible to control the CD-112TRS from a
PC via a suitable terminal program. Connect the
jack REMOTE CONTROL (30) to the RS-232
interface of the computer. Set the following
parameters in the terminal program:
Symbol rate . . . . . . . . . 9600 bauds
Number of data bits: . . 8
Number of stop bits: . . . 1
Parity: . . . . . . . . . . . . . . none
Flow control: . . . . . . . . none
The control commands for all functions of the
CD-112TRS are listed in the tables below. The
terminal program will send them in ASCII code.
Finally, the commands "Carriage Return" (0D
hexadecimal) and "Line Feed" (0A hexadecimal)
must be sent to the CD-112TRS as bytes 4 and
5. Some terminal programs will execute them
automatically or can be adjusted accordingly.

112TRS will send the following message in
ASCII code to the PC:

In case of an input error, it will send the mes-
sage:
+ E R "Carriage Return" "Line Feed"

ning, an interval of at least 800 ms is required.

Protect the unit from dust, vibrations, humidity
and heat (admissible ambient temperature
range 0 – 40 °C). For cleaning only use a dry,
soft cloth; never use water or chemicals.
Note concerning sound interruptions and

tle on the optics of the laser sampling systems. If
this deposit should cause reading errors and
sound interruptions, the unit must be cleaned by
skilled personnel. Please note that there will be
a charge on cleaning, even during the warranty
period!
