8. DIGITAL DATA OUTPUT
The complete programming of the sensors and of the instrument, as well as all
measured values, can be provided as output either internally via a built-in
printer (option D) or externally via the serial interface to an external printer or
computer. The interface modules and the connection to the devices are
described in the manual section 5.2. Additional modules for networking the
devices are described in the manual section 5.3. The complete programming
of the instrument and the sensors, as well as the data output via interface, are
also described in the manual in section 6.
8.1 Baud Rate, Data Format
All interface modules are factory-set and programmed to 9600 baud. To avoid
unnecessary problems when networking several devices the baud rate should
not be modified but the computer or printer should be set up accordingly. If this
is not possible, the values 150, 300, 600, 1200, 2400, 4800 or 9600bd or 57.60
kbd can be entered via keyboard if the rotary switch is in position

The input is started with the key

. Then the value indicated on the display
is flashing and can be altered using the keys and . When the desired
transmission rate has been selected the programming can be terminated by
operating the key

once again. The baud rate setting will be stored in the
EEPROM of the interface module and will then be valid for use with all other

8.2 Device Address and Networking
All ALMEMO

instruments can be very easily networked to centrally acquire the
measured values of several instruments that are located at different places
(see manual 5.3). For communicating with networked devices it is mandatory
that each device has its own address as only one device is allowed to respond
to each command. Therefore, before any network operation it is necessary
that all connected devices are set to different device numbers. This is
performed with the rotary switch in position OUTPUT CYCLE. The key
FUNCTION
can be used to select the function
Address
and, at first, the
currently set device number is displayed (normally factory-set to 00). It can
then be modified by a normal data input (see 5.4).
