NOTE : This submodule can also be set up to operate in LSERIAL mode. See
page 42 for more information about LSERIAL mode.
Use the PANMIITOLXY configuration in conjunction with a Harris routing switcher
to allow control of the switcher via automation system software written for the
Panasonic MARC Type II
1
equipment. In this application, the P12×1-SP will
translate from AV SW’er protocol to the protocol required by the Harris routing
switcher.
The MARC Type II SQC protocol is a half duplex RS-422 protocol in which all
communications are initiated by the controller (in this case, the controller is the
equipment designed to interface with the Panasonic switcher.) The PANMIITOLXY
initializes and sends out a Status Request to determine the status of the
destinations of the Harris router.
The PANMIITOLXY will responds to any request in less than 14 nS, as guaranteed
by the MARC Type II SQC protocol. If a response is sent faster, the PANMIITOLXY
will be ready for further communications. This timing allows any equipment or
software designed for use with the Panasonic MARC Type II AV SW’er to also work
with a Harris router (via the PANMIITOLXY.)
Only remote control is allowed to do SET commands.
The PANMIITOLXY supports all functionality of the MARC Type II AV SW’er
protocol. The features supported are as follows:

Local Enable/Disable — PANMIITOLXY is in local or remote control.

Set Crosspoint — Set the crosspoint data expected to be controlled by the
Harris router.

Read Crosspoint — Returns the crosspoint data expected to be controlled by
the Harris router.

Read All Crosspoints — Returns the all crosspoint data and its status expected
to be controlled by the Harris router.

Set All Crosspoints — Sets multiple crosspoints expected to be controlled by
the Harris router.
