System Access
A Quintech matrix switching system is controlled by a standard Universal Control Module
(UCM). This is typically a separate 1 RU (1.75") module, but it may be built into a matrix
module. The UCM accepts control commands from external sources that tell it how to switch
the matrix or configure various system options. A standard UCM has five control ports that will
accept commands:
Local: Front panel keypad and LCD.
Remote: The Remote In connector. This is typically where other UCMs are connected when
they are configured to operate as remote control panels. If remotes are not going to be used in
the system, this port can typically be used as an auxiliary serial port. It is configured as an RS-
485 port and accepts 9600-baud 8N1 (8 data bits, no parity, 1 stop bit) data. Command data is
sent as an STX/ETX bounded packet with checksum as defined in the protocol document.
Note that the Remote In connector is directly connected to the Remote Out connector since
this is an RS-485 bus connector.
Control In: The PC Control In connector. This is typically where a control computer or PC is
connected. The port can be configured as an RS-232, RS-422, or RS-485 port and accepts 9600-
baud 8N1 data. Command data is sent as an STX/ETX bounded packet with checksum as
defined in the protocol document.
QEC Port: Ethernet. The exact Ethernet port is user-defined with the default Ethernet port set
at
9100 . It accepts the same command packet that is used on the serial port. This makes it easy
for a single driver to be used for both serial and Ethernet connections.
Telnet: Telnet console window. This provides an ASCII interface with a cursor for keyboard
entry of commands.
The system is highly flexible. The access control feature can be configured to be on/off for
each of the five possible control ports on an individual UCM. This also holds true for a system
with a main UCM and multiple remote UCMs. The control port access control must be set
separately for the main unit and each of the remotes.
UCM Control In Connection
The Control In port of the UCM is where serial port data from a PC is accepted. The Control In
port can either be left unused or it can be used for serial communications control of the
matrix. Serial control can be established using any UCM, including remotes.
All operations of the matrix can be controlled from the UCM Control In port which is typically
connected to a PC. The connector is configurable and can communicate in one of three serial
interface standards: RS-232, RS-422, and RS-485. Software configuration is covered later in the
Serial Interface Menu section of this manual.
UCM Control In Connector
The UCM has a standard DB-9 female serial connector labeled Control In on the back panel.
The pin definitions depend upon how the serial port is being used. The connector's pinouts
are shown in see
Figure 3-7 , on page 55.
