Automation Protocol Introduction
Miranda Technologies Ltd Page 22
Overview
The Oxtel unit takes the role of the controlled device, while the automation
system is the controller. Automation commands are sent to the Oxtel unit
from the controller, and the Oxtel unit actions these commands returning
status information as requested.
With RS232 or RS422 communications, the link between a controlled device
and its controller is point-to-point (a single physical connection between the
two).
With later Imagestore products (IS2/2U/3 v2.08 and all products listed below
Imagestore 3 on the list on page 21) automation control via TCP/IP is also
available.
Important Notes
The RS232 pin-out follows the conventionally accepted standard. For
Imagestore 2-based products, and earlier the RS422 pin-outs are based on
industrial automation standards, and do not conform to Sony “9-Pin” or ES-
Bus designations. Newer products including Imagestore HD-TV, Imagestore
300, Imagestore Intuition, Imagestore 750, LGK-3901 and DSK-3901
comply with the 9-pin standard. Please refer to individual product User
Manuals for details.
