Unpacking
The MX800 Radio is securely packed for transport with special foam
packers within a pasteboard container. Before unpacking the MX800
radio, please inspect the MX800 & packaging for signs of damage and
report any damage to your MX800 distributor.
Upon unpacking of the MX800 radio, please ensure that all items
shipped were received, report any missing items to your MX800
distributor. All ports on the rear of the radio should be carefully examined
to ensure that packaging has not become wedged inside them. It is very
important to examine the fan, as operation of the radio will be affected if
any packaging or shipping damage causes the fan to stop working.
Installing the Base Station System
The design of the MX800 allows it to be installed in a 19inch rack.
If you intend to install the radio in an equipment rack consult the
supplier’s instructions for your system.
Ensure that it is in a secure, dry location with sufficient air space around
it to allow for adequate ventilation. It is recommended that the chassis be
earthed.
Power Supply
The MX800 requires an external 13VDC power supply. Spectra
Engineering manufactures an Automatic Backup Battery Change Over
System and single power supplies. The built-in backup system supports
automatic switching to an external power DC battery supply if the AC
power supply fails.
Make sure the [POWER] switch on the back of the PSU is turned OFF
when connecting an AC power cable and also when connecting the DC
power cable for a backup battery (Refer to the Mains ratings label on the
rear of the PSU module)
Note.
The MX800 will draw approximately 7 to 10Amps 50W (band dependent)
& 15Amp 100W opt. on transmit and when external power supply \
batteries are used, the gauge of the DC cable fitted to the 12V supply
connector should be adequate to ensure less than 0.5V volt drop at this
current.
If external batteries are used and are non-sealed Lead-acid batteries
type, placement should be at least 4 m away from the repeater.
No reverse polarity protection.
Be sure both the positive (red) and negative (black) terminals are
correctly connected and an inline 15Amp fuse for 50W or 20Amp for
100W opt. should be fitted on the Positive wire. See example in picture
below (Not include)
Antenna
In radio communications, the antenna is critical importance, effecting the
output power and sensitivity.
The antenna and coax cable should be the 50ohm type, and have a
Voltage Standing Wave Ratio (VSWR) of 1.5:1 or better.
CAUTION: Protect repeater from lightning by using a lightning arrestor.
NOTE: There are many publications covering antennas and their
installation. Consult with your local dealer for more information and
recommendations.
SWR
Each antenna is tuned for a specified frequency range and SWR
may be increased if used out-of-range.
When the SWR is higher than approx. 3.0:1, the transceiver’s
power drops to protect the Power Amplifiers final transistor. Low
SWR allows full power for transmitting. The MX800 has a
software diagnostic SWR meter to monitor the Antenna SWR
continuously.
Duplexer
The MX800 with optional external duplexer kit provides mounting
for a number of different manufactures mobile duplexers.
A duplexer is required when only one antenna is used for both
transmitting and receiving. Select a duplexer according to the
transmitting and receiving frequencies.
See Dealer for further information on this feature
Software Programming
The MX800 can operate in a number of different modes. The
primary alternatives are full duplex, which is the default mode,
repeater and simplex. Using MXtools programming utility the
MX800 can be programmed to suit individual system needs.
This is done thought the configuration menu system, with a
Personal Computer (PC) Widows XP and a RS232 programming
cable.
MXTOOLS is a Base Station Programming Utility specifically
designed to use in conjunction with the Spectra MX800 Base
Station. MXTOOLS provides easy viewing and setup of the
parameters within the MX800 Base Station. MXTOOLS is used
for three main purposes:
• Channel programming and viewing
• Configuration setup
• Viewing and radio diagnostics.
MXTOOLS is a powerful utility giving comprehensive control
over the information within the radio while maintaining an easy to
use user interface simplifying the setup of your MX800 Base
Station.
MXTOOLSRD is an application in which you can diagnose and
log single or multiple MX800 base station(s) data, by working in
conjunction with option T31 board and MXSSU unit or T34
board.
MXTOOLS RD features:
• Real Time Diagnostic through Serial Communication
or Ethernet
• Data Logging (Time Interval period 1 to 60 minutes
or manual log).
A file (dataExcel.txt) is formatted so that user can
import data to MS Excel easily.
• Alarm Logging, depending on the alarm mask
(programmable from MXTOOLS)
In addition to the features above MXTOOLS RD allows
you to connect to a single MX800 radio directly, where
you can log any diagnostic result as well.
Please see the MX800 Technical Manual or contact your dealer
for application notes for further information on MX800 features.
