PURPOSE OF EQUIPMENT
The C-1000/S control unit is designed for use with Wulfsberg's
Flexcomm communication systems. Flexcomm provides FM
communications in low band VHF, high band VHF, UHF and
VHF AM. Flexcomm provides total flexibility for interagency
communications. The units provide channeling capability for all
the FM bands plus the air traffic control band.
The C-1000/S is a fully frequency-agile control unit. It provides
the ability to thumbwheel control all of the authorized Flexcomm
system channels. It also provides 30 programmable preset
channels. And the programming capability to change any of the
preset channel frequencies is built into the control unit. This
built-in operator programming capability can be disabled if the
user desires. Transceivers must be used only on your specifically
authorized frequencies.
NOTE: The C-1000/S Control Unit has shop accessible mode of
operation selector switches. The configuration of the switches
alters the operation of the control and the configuration must be
known to properly utilize the features of the C-1000/S.
Features and capabilities of the C-1000/S that may be internally
enabled/disabled are:
!
THUMBWHEEL LIGHTING - normally the thumbwheels are
back-lit continuously for night use but may be internally
disabled.
!
FREQUENCY AND TONE DISPLAY - normally the display
is off except when the present RCV/XMT switch is depressed
either to preset channel frequency and tone information or to
re-program the channel information. The display may be
configured internally for the display to be on continuously.
!
GUARD CHANNEL PROGRAMMING - may be internally
disabled.
!
PAGE A AND B CHANNEL PROGRAMMING – may be
internally disabled for page A or page B channels or both.
!
MANUAL SIMPLEX CHANNEL - may be internally
restricted to receive only.
!
CHANNEL MEMORY DISCRETE OUTPUTS – may be
shop programmed with each channel to provide control of
external accessory equipment. Should the operator
re-program a channel without access to the internal switches,
pre-programmed channel memory discrete information may
be lost. If the unit has been modified for narrow/wide band
operation, memory discrete number two will not be a user-
defined discrete output.
