Omega Vehicle Security 1400 manual Operational Aspects, Data Handling and Triggering

In addition to the features of ChartScan described thus far, the unit includes:

•Thirty-two TTL (Transistor-to-Transistor Logic) digital alarm outputs and 8 TTL-compatible digital inputs.

•Two programmable scan rates: (1) a programmable scan rate for pre-trigger and post-trigger sampling, and (2) a programmable scan rate for accelerated sampling on-event detection.

•A built in real-time clock that synchronizes the acquisition to the time of day, and provides time and date stamping for trend analysis. Time stamping may be in relative or absolute time.

•Standard RS-232 interface and optional IEEE 488 interface. Connection to computer can also be made via a Hayes-compatible modem.

•256 Kbytes of memory, expandable up to 8 Mbytes. If your application must gather large amounts of data, options are available for expanding the standard 256 kB of memory to 1 MB, 4 MB, or

8 MB. Readings may then be transferred at greater than 300 Kbytes per second over the IEEE 488 bus or up to 9,600 baud using its standard RS-232 serial port. Though the RS-232 serial interface is always available with ChartScan, an interface card must be used for IEEE 488 applications.

•Capable of channel expansion up to 128 channels with the use of a CSN/Exp expansion chassis.
