MX800 Base Station/Repeater

T01 Programmable Channel Spacing

 

For applications in systems that require either\both 12.5kHz and 25kHz channel spacing option T01 allows channels to be programmed for either bandwidth via MXTools. The change in bandwidth is transparent to the user.

This option has become Spectra's standard build, therefore it is not necessary to specify this option at order placement.


 

T02 Option- Programmable CTCSS full duplex encoder and decoder.

 
Provision is made in the MX800 to fit a CTCSS encoder/decoder. The decoder is non-predictive and any valid CTCSS tone can be decoded. Any standard TX CTCSS tone may be associated with the programmed decode tone through the Channel Edit screen in MXTOOLS. Multiple CTCSS tones are programmable for any channel providing "Community Repeater" functionality.

 

T03 Option- Programmable DCS / CTCSS full duplex encoder and decoder.

 
Provision is made in the MX800 to fit a full duplex DCS encoder/decoder.
Any standard DCS code or CTCSS tone may be assigned to any of the transmit or receive channels through the Channel screen in MXTOOLS. Multiple CTCSS tones are programmable for any channel providing "Community Repeater" functionality.
The DCS encoding function provides continuous, repetitive digital word modulation to the transmitter. The decode function controls receiver muting to eliminate all calls that are not coded with the assigned DCS code.

 

T06 Option - Simplex Coaxial Changeover Relay.

 
For simplex applications an internally mounted coaxial changeover relay can be provided. This mounts on the rear panel and the common port protrudes through the chassis providing the simplex antenna connection.

 

T08 Option - VF audio delay for noiseless mute function.

 
This option is intended for two main applications. Firstly when the delay is fitted, the mute (squelch) "crash" characteristically heard when a mobile releases its PTT but the repeater tail continues, it is eliminated. Secondly systems (including Trunking systems) which have mixed voice and data on a channel can delay the VF signal to line and air so that in the event that a data stream is detected (by the data controller) the VF to line and air can be disconnected for the duration of the data burst thus avoiding radio system user annoyance.

 

T10 Option - Low RX standby current drain option.

 
For solar powered sites and other power critical applications the MX800 is capable of a Power Save (Low Standby Current) Mode.

 

T12 Option - Add external reference oscillator input facility for TX only.

 

Option T12 provides for the TX reference frequency to be externally injected. An SMB connector is fitted to the exciter and an internal cable is provided from there to a chassis mount BNC Type connector into which the external reference frequency is injected. RX IN becomes N-Type.
As two-point modulation is not possible with this configuration, the transmitter frequency response is restricted at the low frequencies ranges. If a DC audio response is need then please see T36 option.

 

T13 Option - Local speaker and MIC socket.

 

For applications needing a user interface at the base station the MX800 is available with the Local Control option for loudspeaker with volume control and RJ45 microphone socket. Microphone not include.

Loudspeaker and Volume Control
A 1 Watt loudspeaker is provided to monitor 'on air' received audio as well as transmit audio from line. Volume control is provided by means of a volume pot or a 3-position toggle switch adjacent to the loudspeaker.
The speaker has a link selectable connection to a tone output from the micro controller. This may be used in conjunction with the appropriate software configuration to generate an alert tone to the user.
Microphone Socket
An RJ45 socket is provided for connection of a microphone. This socket is wired compatibly with the Motorola GM300 microphone.
Mute / Squelch Adjustment
Provision is made to optionally locate the squelch control potentiometer behind the front panel. A screwdriver hole is provided in the front panel to access this adjustment.


 

T14 Option - Local channel change on front panel (99 channels).

 

For applications needing a user interface at the base station the MX800 is available with the Local Control option for loudspeaker with volume control and RJ45 microphone socket.


 

T19 Option - Universal Line Interface Board

 

Introducing the new T19 Option for the MX800 Base Station/Repeater! The T19 Option is an internal PCB card that enables the MX800 to be easily integrated into a variety of legacy and modern networks. When fully configured, the T19 Option offers more than 10 new system-related features, such as :

  • Programmable Digital Voting Tone Encoder
    A variable tone used to remote indicate the Base Station received signal strength.
  • PTT Tone Decoder with AGC
    An in band tone decoder used to key the transmitter during the presence of speech.
  • 2/4 Wire Operation
    Hybrid Interface to line is user configurable to either 2-wire or 4-wire full duplex.
  • Dual E&M Interface
  • Rx Status Tone Encoder with Line Equalization
  • SINAD Voting

 

T29 Option - Balanced and Isolated VF I/O with E&M Lead

(Same as Opt T05 but RJ45 pinouts are to AS3080).
 

Option T29 provides the balanced and isolated VF I/O as well as isolated E (PTT) and M (Mute) leads, as per option T05.

The E lead is opto isolated and may be asserted by applying a DC voltage between 5V and 48V.
The M lead is relay isolated and the common and normally open contacts are brought out via CN9 (RJ45).

Provision is also made to internally source the activation voltage (+12V DC) via jumper settings.


T35 Option - Balanced and Isolated VF I/O with E&M Lead.

Same as T29 but mounted in place of the monitor connector (DB9F –CN2) within the MX800. The T35 is used instead of T29 if the build also requires a conflicting hardware mounting option ie. Normally used in conjunction with T34/T58 - Internal Ethernet.



 

 

T31 Option - Network Expander card

 

The T31 network adapter is a small circuit board that is installed inside the MX800 transceiver to enhance serial communications to the MX800. This is achieved because the board implements a protocol especially designed for efficient multi-drop serial communications.
The T31 board intercepts the serial data port of the MX800 encoding and decoding the external data stream, converting it to/from standard MX800 data required by the MX800 Micro-controller board. It also intercepts the MX800’s DB25 Digital I/O connector and provides additional digital inputs to allow more than the standard 16 network addresses to be set externally. The additional pins required to support the additional network address inputs are available externally on a DB44 high density connector that replaces the standard DB25 female connector (CN3) of the MX800. CN2 is also located on the board and it’s connection to the MX800 Micro-controller board provides the power supply for the T31 option board.



 

U71 Option - ID , Channel dongle and TX Power select to suit Standard MX800.

 

The U72 has a single DB25 male connector and four rotary switches. Two of the switches allow the selection of a pre-programmed MX800 channel, the third allows the selection of the a network address id and fourth allows RF power control selection.


 

U72 Option - ID and Channel dongle to suit T31.

 

The U72 has a single DB44 male connector and four rotary switches. Two of the switches allow the selection of a pre-programmed MX800 channel and the other two allow the selection of the extended network address.


 

U73 Option - ID and Channel dongle to suit T31 with D25 port replicator.

 

The U73 dongle allows not only the selection of the network address and channel, but also provides all of the connections normally provided by CN3 on the standard MX800.


 

T34 Option - Internal Ethernet

 

The T34 Option provides data access to the MX800 Base Station/Repeater using Internet/Intranet TCP/IP Protocols. Using the MXTOOLS software, remote control and diagnostics monitoring of the MX800 can be performed.

Newer Version T58.

T36 Option - TX Ref Oscillator input and Modulator

 

The T36 Option extends the modulation capabilities of the MX800 when an externally locked reference input signal is required. In Simulcast systems where the application does not just require just Voice modulation but also the additional capability of either Data, POCSAG, CTCSS or DCS, then a transmitter is required to have a modulation bandwidth that extends to down towards 5Hz or better still to DC (0Hz). This new option provides that capability by incorporating digital RF techniques. In addition, the carrier can be offset in each transmitter in steps of 1Hz.

Features include:

  • RF carrier programming and resolution to 1Hz accuracy
  • Programmable RF carrier offset from nominal to ±25 kHz in 1Hz steps
  • Supports reference input frequency from 8 to 25 MHz in 1Hz steps
  • Menu setup via serial port
  • Installed inside MX800
  • Allows use of non standard reference frequencies
  • Can be retro-fitted to all MX800 radios
  • Can still have internal reference 1PPM, 0.01PPM or special.
