Help - Net-Control alarm port and baudrate 08.09.92
Besides the possibility, to write the alarm messages
into the logfile and broadcasting them to the other
Net-Recorders (Net-Control stations), you can also
configure special outputs to the serial or parallel
port.
You have to select in ⌠-Special Alarmoutput- Port:⌡
if you want to send the messages to one serial port
(⌠COM1⌡ or ⌠COM2⌡). (Don't forget the correct baudrate.)
The messages are sent ≤without≥ flow control and DTR is
asserted before the message and deasserted after it.
If you select ⌠LPT1⌡ or ⌠LPT2⌡, the value assigned to the
alarm message will be sent to the choosen parallel port.
≤Assigning values to alarms:≥
To every alarm you can assign one value between
1 and 255. This value can be edited in decimal or
in binary. The default setting of ⌠0⌡ means, that
this alarm has ≤no≥ value assigned to it.
≤This value can be used in two ways:≥
You can define your own priority for the alarms
(value 1 - unimportant to value 255 - critical alarm).
Net-Control writes assigned values in the corresponding
alarm messages behind one ⌠°⌡ character.
On the other hand this value is written to the parallel
port, if in configuration menu the alarm port LPT1 or
LPT2 has been choosen. By additional hardware (for
example an 8 channel centronics relais-interface)
you have the possibility of special reaction to alarms.
