| ComSched
for Windows
is designed to control the following equipment:
|
|
|
·
One
or more (up to sixteen) motorized satellite antennas. Each motorized axis must be equipped with a position sensor
such as an optical encoder or potentiometer.
|
|
|
·
One
or more (up to sixteen) motorized feedhorns, one per antenna.
Each feedhorn must be equipped with an optical encoder or
potentiometer.
|
|
|
·
One
or more (up to four) EC8 or CTI-850 Satellite Antenna
Controllers.
|
|
|
| ·
One
or more satellite receivers. Compatible
satellite receivers include:
|
|
Drake
ESR-1250, ESR-1252, ESR-1255
|
|
Scientific
Atlanta 7500, 7530, PowerVu
|
|
Standard
MT810, MT830, MT930B
|
|
Tandberg
Alteia
|
|
Receivers
of different types may be intermixed within a single control unit.
|
|
|
| |
|
|
| ComSched
for Windows
allows the user to set up and execute a schedule of
future events, called the MASTER SCHEDULE.
Several hundred "events" can be stored on disk. Each
event may consist of any or all of the following:
|
|
|
·
Move
any antenna to any specified satellite.
|
|
|
·
Adjust
the antenna feedhorn to the proper polarization.
|
|
|
·
Assign
receiver settings (transponder number, visual carrier frequency, aural
subcarrier frequency, C/Ku input relay, and H/V input relays).
|
|
| |
|
| ComSched
for Windows
automatically
executes events in chronological order, so events may be entered in any
random order. |
|
| |
|
|
| ComSched
for Windows allows
the user to adjust the antenna and the receivers directly from manual
control screens.
|
|
| |
|
|
| ComSched
for Windows
is
configured to run on an IBM-compatible Personal Computer (PC).
Two PC options are available:
|
|
|
·
The
PC can be supplied by the user. The
PC must be equipped with keyboard, monitor, mouse, accurate on-board
time-and-date clock, hard disk drive, floppy disk drive, Microsoft Windows 95 (or later), and at least one serial communications
port.
|
|
|
·
A
rack-mounted PC, with 14" rack-mounted color monitor, is available
from CTI.
|
|
| |
|
|
| ComSched
for Windows
operates
over an electrical connection called the Remote Serial Link (RSL)
between the PC and the controller.
This link can be implemented with any of the following circuits:
|
|
|
RS-232
|
|
|
RS-422
|
|
|
RS-485
|
|
|
Telephone
line, either leased or dial-up
|
|
|
A
two-wire full-duplex audio circuit
|
|
|
A
pair of subcarriers on a microwave STL
|
|
| |
|
|
| ComSched
for Windows
and ComTrack can be used
together on the same antenna. Any
satellite for which ComTrack has been allowed to establish a tracking history can be
scheduled in the ComSched for Windows
MASTER SCHEDULE. Whenever
ComSched for Windows
moves the antenna to the satellite, ComTrack takes over and uses the stored historical information
to locate the satellite.
