INSTALLATION
SYSTEM INSTALLATION
Because the features of Excalibur SE and the Matrix Switching
System are so versatile, it is important to plan the installation
carefully to gain full advantage of these features. It is
recommended that the user become thoroughly familiar with
the capabilities and operating modes of the Matrix Switcher,
determine the needs of the facility, and set up the Excalibur SE
system only after thorough planning.
The weakest links in any security/CCTV system using
Excalibur SE will be the computer hardware and the quality of
the CCTV system installation. It is strongly recommended that
a computer of the highest quality and reliability is used. An
uninterruptible power supply is required (UPS), as opposed to
a standby power supply (SPS) which is sometimes billed as a
true UPS. The software is designed to reload critical data at
regular intervals to help avoid memory corruption problems
from power surges, glitches, and momentary outages.
However, it is still essential to use computer hardware of the
highest quality, to use a UPS to control and condition the
power, and to provide a stable power circuit to insure reliable
control and monitoring.
PC Configuration Requirements
The minimum computer configuration required to operate the
Excalibur SE program system is a true IBM PC compatible
computer, with the following:
1. At least a 386DX 33 Mhz or 486SX 25 Mhz processor.
2. A minimum of 4 Mbytes of RAM extended memory. The
number of maps and icons available is directly related to the
amount of RAM; a minimum of 4 Mb is recommended.
3. A minimum hard disc capacity of 100 Mbytes.
4. A two-button mouse or mouse emulating input. It is not
possible to use the Excalibur SE program without a mouse
or mouse emulating input device.
5. Windows 3.1 Operating Software; DOS 5.0 or greater.
6. A Windows compatible sound card to annunciate operator
actions (optional).
PC RS-232 Communications Ports
For proper RS-232 communication with the Excalibur SE
workstation PC, the pin definition and the DTE (Data Terminal
Equipment) or DCE (Data Control Equipment) configuration
of each connected device must be observed. All American
Dynamics equipment, including Matrix Switching System
Controllers, are configured as DTE devices.
For DTE-to-DTE communications between a Matrix Switching
System Controller and the Excalibur SE workstation PC,
connect a three-wire, shielded, 18-AWG RS-232 cable from
the Excalibur SE workstation PC RS-232 port to a Matrix
Switching System Controller RS-232 port, as follows:
a. Connect GND from the Excalibur SE PC port to GND on
the controller's RS-232 port.
b. Connect RCD from the Excalibur SE PC port to XMIT
on the controller's RS-232 port.
c. Connect XMIT from the Excalibur SE PC port to RCD
on the controller's RS-232 port.
Refer to the RS-232 port connector pin definitions and setup
instructions in the appropriate Switching System Controller
Installation Manual.
PC Printer Port
The 25-pin HASP plug supplied with the Excalibur SE
software must be connected to the PC printer port, LPT1.
Figure 1-1, page 1-3, illustrates a typical Excalibur SE
workstation PC configuration.
