The following relay outputs are available for further signal processing. The maximum rating
for the relay contacts is 60 V a.c./1 A.
The contacts are numbered from bottom to top.
Description of the operation mode of the Digital Out. The pin assignment for contacts 8 to 16
follows the same order as for pins 5 to 7.
The actual pin setting can be seen under Info / View internal data.
Softkey 2: Baud rate and end sign
Settings for the baud rate selectable between 1200 and 19200, as well as end sign between
CR+LF, CR or LF.
Softkey 3: Data, Parity, Stop bits
The settings for Data (7 or 8), Parity (Even, Odd, None) and Stop bits (1 or 2) can be
selected
Softkey 7: RS 232 Protocol
The protocol from the RS 232 can be chosen between: Legacy size, Diagnostic, and ASCII
code.
CAUTION:
All pins of digital I/O, digital out and recorder must not be connected with voltages higher
than 60 V d.c./25 V a.c. (to grounding equipment conductor) or reach this threshold.
