Connecting Alarms to the Intellex
The alarm connectors on the back of the unit accept up to 18 alarm inputs and 16 alarm outputs.
The alarm outputs are TTL outputs 4VDC, 6 mA.
Note
The layout of the rear panel varies slightly with different motherboards.
Note
For EMC compliance shielded twisted pair alarm cable should be used on the DVMS with the
shield terminated at the earth point.
The polarity of all alarm inputs is programmable. However, the polarity of all alarm outputs is
active–high. Alarm outputs are initialized to inactive–low on power-up.
Attach the alarm inputs, outputs, and grounds to the connectors, according to the pin assignment.
Use the Time Sync Signal (Alarm In 17) to reset the system time of the Intellex to the nearest hour.
Use the Export Signal input (Alarm In 18) to start a Fill CD operation without access to the normal
user interface. Use a contact closure, such as an external switch, to execute the Fill CD command
to export the last 500 MB of data to a CD
Time Time resets to
<30 minutes before the hour Forward to the next hour (0 min, 0 sec)
<30 minutes after the hour Back to the previous hour (0 min, 0 sec)
