COMPUTER COMMUNICATIONS
The Sample Sequencer contains a communication port allowing it to send and receive any information
and accept operating instructions from a remote computer. Many other Sentry controllers can be on
the same line in a network. The connected computer can process the information for display,
historical records, annunciation and communication to other systems.
Included in the Sample Sequencer is a complete RS-485 serial communication system requiring a
single twisted pair cable. Up to 16 or more Sample Sequencers and/or Sample Sentry controllers can
be connected via a single twisted pair line to a computer with a RS-485 communications card. Simple
RS-485 to RS-232 converters are available if required.
Sentry offers a software program, SEQUENCE
 to conveniently provide network communications
with a PC.
SEQUENCE Monitor Program:
For IBM compatible PCs, this program controls and maintains the complete status of up to 16
sequencers and on each Sequencer all 8 sample points. A programming and control screen allows
easy editing of control data and testing of each function, and for each connected Sequencer.
The input data is stored in computer files so that a historical record is kept. The program can present
this data on screen in tabular or graphical form or it can be printed. More details are available in the
Sequence
 Monitor manual.
