2.2.1 MXTOOLS Utility
MXTOOLS is a programming utility used to program channel data, configure
and perform remote diagnostics on the MX800. It runs on a PC compatible
computer and the MXTOOLS Inbuilt help menus cover use of the program.
2.2.1.1 MX800 Networking
See New Option T31 & T34 also.
At sites where more than one MX800 is located it is possible to "bus" the
RS232 lines to allow up to 16 MX800s at one site to be addressed on a single
RS232 port. Hardware facilities provided on the MX800 Micro controller
card provide isolation between transmit ports. When MX800s are bussed in
this way JMP24 in each radio must be set so that
1. At least one radio and no more than four are set as masters.
2. All other radios are set as slaves.
Refer to Table 2-1, in section 2.2.2.1 for details.
In addition to this, each radio must be assigned a unique address. This
address is assigned as a binary code through CN3. Four address lines are
available on input port A where bit 4 is the LSB and bit 7 is the MSB. These
lines should be pulled high or low depending upon the setting of JMP19.
Default is active low so that GND = Logic 1, Refer section 2.2.2.5.
The RS232 cable should be made up such that all MX800 transmit ports
(TXD) are common and connected to the PC receive port (RXD) and all
MX800 receive ports (RXD) are common and connected to the PC transmit
port (TXD).
MXTOOLS automatically polls the bussed radios to determine which
addresses are active when the "Use Network" button is selected in the initial
connect screen (MXTOOLS version 2.8.1 or later).
