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. |
|
Obsolete - 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. |
|
Obsolete - 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. |
|
T03B 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. Multiple CTCSS, Supports 39 EIA Standard Code Frequencies. 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. |
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 |
|
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 :
|
|
T29 Option - Balanced and Isolated VF I/O with E&M
Lead
|
||
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. 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. |
|
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.
