9. DIGITAL DATA OUTPUT
The serial interface can be used to completely program the instrument and
sensors or to query the programming (see man. 6.). Furthermore, it is possible,
as described in sections 7.2 and 7.3, to provide outputs of manual and cyclic
measurements online, or offline after a recording (see 7.4), to a printer or
computer. The various interface modules can be connected to socket A1 (3).
The connection to the devices is described in the manual section 5.2. Modules
for networking the devices follow in section 5.3.
9.1 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, 9600 bd and 57.60
or 115.2 kBd can via keypad be entered in function BAUD RATE ´BR´.
The input can be started by a lo
ng press of the key . The display will

PROGR
start to flash and can be modified by using the keys ▲ and ▼. When the
desired transmission rate has been selected the programming can be
terminated by operating the key . The baud rate setting will be stored
▲
PROGR
in the EEPROM of the interface module and will then be valid for use with all
other ALMEMO
®
devices.
Function BAUD RATE ´BR´
Selection with key F2:
U n 9 6 0 0 BR
Example:
Output to interface ´U´, format ´columns´, 9600 bd
Data format: unchangeable 8 data bits, no parity, 1 stop bit
To change the baud rate for a quicker readout of a memory
connector, via readout cable ZA 1409-SLK, the memory connector
must be plugged into socket A1 and the baud rate must be
programmed as shown above.
9.2 Output Formats for Lists of Measuring Data
For measuring point scans (s. 7.2/3) the measured values can be provided in
different output formats (s. man. 6.5.5, 6.6.1). Apart from the standard list
format, with all measured values given in a list, the column output format
allows for a clear and space-saving printout in columns. For this purpose, a
printer will automatically switch to the condensed character mode. Alarm lists
during the measuring cycle are not available for this format. The spreadsheet
format is available to further process measuring data by means of spreadsheet
