2-2 General Information ChartScan User’s Manual
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.
