Introduction
The Digital Input / Output Module (DIOM) enables the
'Orbit Network' to interface with the outside world. The
module provides 8 general-purpose input / output lines,
housed in the standard Orbit Module case. Each line
can be individually configured to Input or Output.
Input / Output line are connected via a 0.5-meter flying
lead and a 15-way D-type connector.
This Manual
The manual describes the technical specification of the
product enabling you to connect to the DIOM. All
communication with the DIOM, including configuration
of the unit, is carried out using the 'Orbit Command'
language, which is described in detail in this manual.

CAUTION:
Failure to observe the limits in this specification
could result in damage to this equipment and
any equipment connected to it.
NOTES:
This equipment contains no user serviceable parts.
This equipment must be returned to a Solartron Dealer
for all service and repair.
Low Voltage
This equipment operates at below the SELV and is
therefore outside the scope of the Low Voltage
Directive.
DIOM General Specification
