3. C ONNECTING TO THE M ATRIX
3.1 CONNECTING THE MATRIX PORTS
The following drawing shows the rear view of a fully equipped 6U rack. Connectors are
provided for the P.C., status alarms, panels and externals. These connectors are wired as
detailed below. Connector types and pinouts for the Commander rack connectors are given.
The numbering of port outputs is indicated on the connector plate on the right hand side of
the rear of the rack. Port 1 is the top right connector, port 6 the bottom right; port 91 is the
top left and port 96 the bottom left. In systems with more than 1 rack, numbering continues
from port 97 in the second rack, as indicated by the printing.
The frame number (1 to 4) is indicated by appropriate marking of the boxes at the bottom of
the connector plate.
Early systems did not have printing on this plate. Use this drawing as a guide.
3.2 CONNECTING THE PC TO THE COMMANDER SYSTEM
A number of different options are available, depending on the type of computer and size of
the matrix. These are:
• A laptop or desktop PC communicating directly via a free RS232 (COM) port. See
section 3.2.1.
• A Trilogy 500-16-03 download converter box. This interfaces the serial port on a laptop
or desktop PC to the transputer (high-speed) download port on a Commander matrix.
See section 3.2.2..
Connect the PC to the D9 type plug labelled "20MB/s PC link" on the rear right side of the
matrix. In a multi-frame system (i.e. >96 ports) the PC may be connected to any of the
available PC connectors but we would recommend frame 1 as the default. Initially, we
suggest establishing control of the system using the supplied cable.
3.2.1 CONNECTION VIA A PC COM PORT USING RS232
For the later releases of PathFinder 4.16 and all releases of PathFinder 4.2x, provided the
system is fitted with 500-02-12 Talkback Controller cards, the matrix may be upgraded to
allow serial communication from a free computer COM port. It may be necessary to
exchange the matrix rear connection plate: alternatively, an external RS422 to RS232
converter must be fitted. Please contact Trilogy Communications for further information.
The factory default configures the matrix for RS232 communication. See section 3.4.3 for
wiring information.
