The 2.4 – 2.6GHz receiver tunes from 2.304ghz to 2.559ghz,
and additional O. Band channels [6] from 2.512ghz to 2.659ghz, a
total of 256 frequencies. The separate 1.2GHz receiver tunes 1240
to 1367.5MHz, 127 frequencies.
Mechanical Details
All
frequencies can be accessed from the front panel 8 way dip switch
after consulting the “frequency table/setting” list
provided. Additionally ten frequencies can be accessed with the
L.C.D. display controls. These are all the 6 channels on O band
and 4 on I.S.M. band [2.4 GHz] allocation. The receivers are available
on 1.2 GHz band, or the 2.4 GHz to 2.7 GHz band.
From
left to right the front panel controls are:
• “on screen meters on/off” switch. This will
activate an “on screen display bar” showing signal
strength, and , if selected A.F.C tuning.
• The “8 way dip switch” is used to manually
select the frequency required (by consulting the frequency/select
position list provided).
• The “red LED” has two functions, selected
by the “mode switch.” (NB. In none LCD models changing
mode/functions, can be achieved by using the RS232 PC facility!).
LED “one” has it functioning as a “out of lock”
indicator, ON when the PLL is not locked for any reason. The “second”
LED has its functioning as a “video detect indicator”,
ON when the receiver detects syncs from an incoming signal (this
signal could be useful to activate alarms or repeater controllers
as a “sync detect circuit”).
• The yellow LED is a “power on” indicator activating
when 9v-16v power is on.
• The far right switch is the receiver “on/off”
switch.
NB.
The receiver is polarity protected!
The
back panel contains sockets for the following:
• A 2.1mm round power socket [12v], a four pin XLR plug,
also for power, pin 1=negative, pin 2=positive.
• Two XLR 3 pin plugs for low impedance balanced audio channels,
1 and 2. Pin 1=shield, pin 2=positive, pin 3=negative.
• A BNC “video output” socket
• Two RCA sockets for unbalanced hi impedance “audio
outputs”
• One RCA socket for “video out”. N.B. The two
“video outputs’ are not independent so only one should
be used at a time to avoid "double termination".( the
same applies to the audio!) The far right socket is a "SMA"
socket for attaching the aerial.
• A 15 pin "D". socket is provided for a "RS232"
control to connect to a "PC" or remote control facility.
When connected to a "PC" with a "hyper terminal
program", then a box appears with all steps and facilities
laid out, just follow the prompts
