  10. Programming With Programming-Menus

10.6.1 Data cable

The serial interface can be used to output cyclic data logs, all function values
of the measuring menus, as well as the whole programming of the sensors and
the   device   to   a   printer   or   computer.   The   ALMEMO

®

  data   cables   and   the

connection to the instruments are described in the manual section 5.2. Other
modules for networking the instruments follow in the manual section 5.3. 
All available interface modules are connected to the socket A1 

(2)

, exception:

network cables ZA1999-NK to network a further instrum. are connected to A2.
Under the prevailing socket the menu indicates:

Outout Socket A1:

 

DK Data cable

Variant 0: Standard interface always active

0:  RS232

The baud rate is also stored in the cable connector:

Baudrate:       9600 Bd

10.6.2 Relais Trigger Cable

The combined input and  output cables  (ZA 1000-EAK) and the relay trigger

analog adapter ZA 800x-RTA (see manual 5.1.2/3) provide max. 4 switching

contacts for the triggering of peripheral devices and trigger inputs (see manual
6.6.4). They are connected to the output socket A2 

(2)

 and their function can

be programmed (see manual 6.10.9):
