Introduction 1

Easy Setup:

The I/O PLEXER has its own power supply, no need to purchase or reserve
space for an external supply. A push-button and an on board LED indicator
configure unit address and baud rate. Removable terminal strips allow
attachment/ removal of multiple cable sets in one step. This modularity greatly
reduces troubleshooting and upgrade delays.

Protocol Compatibility

The I/O PLEXER instruction set core complies 100% with the OPTO-22
OPTOMUX serial communications protocol for remote data acquisition and
control. With speak-only when spoken to protocol, which only uses ASCII
printing characters, a Host transmits inquiry requests to the I/O PLEXER to
determine the status of its various process inputs. Based on the reported status,
the Host makes control decisions and transmits this data, as instruction messages,
to the I/O PLEXER which uses the new decisions to make the proper changes to
its various actuators. Both the Host and the communications link are essential
elements in this data acquisition and process control scheme.

Originally, the protocol only allowed for all analog or all digital I/O chassis.
Depending on application requirements, each I/O PLEXER can respond to up to
five different function addresses. With their abbreviations they are:

MC

Master Unit Control function address

MD

Master Unit Control digital I/O function address

MA

Master Unit Analog I/O function address

E1

1

st

Expander Digital I/O function address

E2

2

nd

Expander Digital I/O function address

E3

3

rd

Expander Digital I/O functions address

It is the multiple function addressing capability of the I/O PLEXERs that allow s
them to utilize,

without modification

, software developed for competitive

products. Similarly I/O PLEXERs can operate simultaneously on the same
network with these products.
