MX800 Transceiver Options
3.18 T34 Ethernet option
The T34 Ethernet Option is a small circuit board that is installed inside the
MX800 transceiver to allow diagnostic data from the MX800 to be sent over
a UTP Ethernet link.
The T34 includes a web server to output web pages for analysing the health
of the host MX800 using a standard HTML web browser.
The T34 board intercepts the serial data port of the MX800 and converts the
MX800 data to and from IP packets that are transferred over the Ethernet
link.
When using the Mxtools software, the T34 board sends and receives data to
the MX800 motherboard normally as long as communication via the Ethernet
connection with the MX800 is inactive.
Due to ongoing development please refer to www.spectraeng.com.au for the
latest information regarding this option. A technical manual is available for
this option please contact sales@spectraeng.com.au for a copy of this
manual.
3.19 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). The option provides this capability
by incorporating digital RF techniques. In addition, the carrier can be offset
in each transmitter in steps of 1Hz.
New 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
