Extern Bias - Enables you to define a
calibration value according to the
external event device and cable used.
Time Guard - If two or more events
take place during the time (in
seconds) defined, only the first event
will be recorded. Enter 0 to accept all
events. The shortest recording time is
1 second, however all events will be
counted.
If an external device is connected to
the sensor an OWI or LB2 message
can be transmitted at the time the
event takes place.
To enable messages, change Notify
Msg to ASCII (OWI) or Binary (LB2)
and press NPORT (F5) to select the
port and device through which the
message shall be transmitted.
If both event input ports are used
select the Event Port number and set
the parameters for each.
Info to Log - Select the information
that shall be logged with the Event
record.
Bias Intern - Set to User, for setting
your own calibaration value for a
particular sensor. Factory uses
default settings.
Intern Bias - When Bias Intern is set
to User, set a calibration value here
for a particular sensor.
Press PARAM (F5) to modify
additional parameters. Scroll down and enter a Description.
This description will be recorded with
the event record. This is particularly
useful if two event input ports are
used at the same time in order to
differentiate between the two event
records.
The technical specification for the
Event Input port are as follows:
Pulse type: TTL, positive or negative
going pulse
Pulse Length: Minimum 125 nsecs
Voltage: TTL level (~5V, min. 3.3V)
Pin definition: Center = signal,
case = ground
SR530 Connector type:
