Serial RS 232 interface (rear side of Millimar)
A printer or computer can be connected to this
9 channel interface. If necessary (e.g. if the mea-
sured value memory is full and there is a risk that
the first entry will be overwritten by the most
recent), data that has already been acquired can
be printed out on a connected printer and then
deleted.
If a computer is connected, the following pro-
cesses can be executed depending on the set-
ting of the Millimar interface
– Measured values can be transferred to, or
queried from, the computer
– Parameter settings can be changed or que-
ried by the computer
– Measurements can be initiated or terminat-
ed by the computer.
Data saved on the computer can be processed
using appropriate programs (statistics programs,
QA programs) – see Chapter 14 “Using the serial
interface (RS 232)”.
Parallel interface (rear side of Millimar)
The 25-pin interface marked with “I/O” enables
data to be transferred to and from other instru-
ments in the Millimar range (e.g. footswitches)
or a programmable controller for e.g. automatic
sorting processes (see Chapter 15 “Using the
parallel I/O interface”).
Connection for power supply unit (rear
side of the Millimar )
The power supply unit is plugged into the con-
nection marked with “9 V =”. This power supply
unit covers a voltage range between 100 V and
240 V and a frequency range of between 47 Hz
and 63 Hz.
No other power supply must be
used.
On/off switch (rear side of the Millimar)
Millimar is switched on and off using the on/off
switch.
Once the unit has been switched on, the soft-
ware boots and the display indicates in se-
quence the type of instrument (C 1208 C 1216
or C 1240), the software version number, the
compatibility of the probe inputs, and finally the
standard display elements.
