are available. Three point (25%, 50% 75%) self-calibration is provided in software to

reduce or remove errors introduced by input offsets.

Sample rates up to 4000 S/sec and data averaging from 1 to 4000 samples are

selectable through configuration options. Data averaging can be expanded to include

larger sample sets through the use of BayTech, or commercially available, application

software. Time stamping or "Time Tagging" of data is available through the use of a

"time-of-day" clock located in the base unit. A time tag includes month, day, year,

hour, minute and second.

Data samples are supplied to the host computer/controller from any of the following

modes:

1. Upon user request (COMMAND).

2. At a specific date and/or time (SCHEDULE).

3. Real time sampling (i.e., as samples are received or IMMEDIATE).

THE V78 CRM-1 eight channel, control relay module is a microprocessor controlled

plug-in unit designed for use with the BayTech M16 Data Acquisition Controllers.

The main feature of the CRM-1 is eight (8) fully programmable, electromechanical,

form-C, single-pole-double-throw (SPDT) relays. Each relay has a set of normally

open (NO) and a set of normally closed (NC) contacts.

All relays on the V78 CRM-1 are programmable to change state by sending data

commands or via time schedule by a host computer/controller. The status of a relay

(energized or de-energized) may be requested by a host computer/controller. The

relay status may consist of buffered data representing the history of changes in the

state of a specific relay or the current state of a specific relay. The relay status may

be provided with a "time stamp or "Time Tag" which is available through the use of a

"time-of-day" clock located in the base unit. A time tag includes the month, day,

year, hour, minute and second the relay status was taken.

Relay status data is supplied to the host computer/controller in one of the following

modes:

1) Upon user request (COMMAND).

2) At a specific date and time (SCHEDULE).

3) Real time reporting of events (IMMEDIATE).

NOTE: An event is the change-in-state of a relay (i.e., energized to de-

energized or vice versa).

Signal input connections to the CRM-1 are made through a standard DB-25F (25 pin

female) connector.
