1Introduction
This document describes usage of MX2400 device plugin.
The MX2400 device is represented by a minimum of four virtual devices: Master, IO interface, Matrix and
Multimeter. Optionally there can be also DIO cards device. Each of them controls the specified section of
MX2400.
Plugin files:
FpcMx2400.dll (main library)
FpcMx2400.local.xml (localization)
Lcs.Fastboot.dll (bootloader library)
Lcs.Printing.dll (print library)
PdfSharp.dll (print to PDF capability)
2Configuration
Plugin requires to configure the target MX2400 device(s) in the configuration dialog:
In the list of configured devices, insert new row by entering IP address of target MX2400 to be connected.
After dialog is closed, the new devices will appear in the detected device list, if connection was successful.
When re-open the configuration dialog, you can see the MAC address of target host and status information.
Default IP address
192.168.100.250
Mask
255.255.255.0
Default ports
2400 and 2401 (see
note below)
Ports note:
Two ports are used - 2400 and 2401. First is for the control channel and second for the asynchronous event
channel (i.e. for IO interface). Port numbers cannot be changed.
IP address can be configured using the service terminal.
There is a web-based administration, accessible on port 8080 (enter "http://<your-mx-ip-address>:8080" to
your web-browser). Actually it only shows summary information and list of detected cards. No configuration is
possible to do here.

2.1 Service terminal
MX2400 supports the low-level configuration using the RS-232 service interface. The connection to computer is
done using the RS-232 (DSUB-9) connector on the master card (see the Hardware manual for description).
The service interface emulates standard VT100 ANSI terminal. It is recommended to use the PuTTY
software or any other VT100-compatible ANSI terminal.
2.1.1 Connection
Parameters of communication:
115200 bps, 8 data bits, no parity, no flow control

The easiest way how to connect using the PuTTY is via command-line:
putty.exe -serial COM1 -sercfg 115200,8,n,1,N
Replace COM1 argument for COMx that you really used.
You can of course connect using the PuTTY's GUI - do not forget to enter correct baudrate (115200 bps) and
configure the serial communication:

5.2 Routing
Generally, routing is about interconnection of internal card's buses to main back-plane buses (BUS 1 - 4).
MX2400 has two routings:
Card routing - define LCMX card interconnection of internal buses to main bus
Master routing - define Connection card interconnection of inputs/outputs to main bus
This chapter describes a little bit the internal electrical solution and simplified schematics of routing for
understanding what is controlled by commands.
5.2.1 MX card routing
MX card routing is about interconnection of LCMX card internal A and C buses to main back-plane BUS 1 - 4
.

Full diagram of MX card routing
LCMX card has internally two split buses: A and C. Each bus consists of L and H line.
A/C and L/H results to 4 signal lines in total:
AL - bus A, line LOW
AH - bus A, line HIGH
CL - bus C, line LOW
CH - bus C, line HIGH
Routing is electrically controlled by set of routing switches SW AL-* (for bus A, line LOW), SW AH-* (A/
HIGH), SW CL-* (C/LOW) and SW CH-* (C/HIGH).
Using routing switches above you can connect them to corresponding (L/H) main back-plane buses: AL to
BUS 1-4 L, AH to BUS 1-4 H and so on.
L line of the card is possible to connect only to L line of main bus (and the same for H line). Routing does
not allow to connect i.e. AL to BUS 1 H.
Because of impossibility to interconnect different lines (L to H), it is possible to simplify the routing schematic
of every card to following matrix:

Any cross-point of Bus 1-4 and AL/AH/CL/CH represents a corresponding switch. Cross-points of AL and Bus
1-4 means switches SW AL-* and so on.

Full diagram of master routing/Connection card
Connection card controls routing of following signals:
Bus multiplex (CH-1 to CH-4) general inputs/outputs
Multimeter (SENS/MEAS/I-MEAS) for full external measurement (2W/4W resistance, voltage, current)
Power supplies inputs (PS-1/PS-2) for power supplies connection
Power supplies outputs (PS1O/PS2O)
Each line L/H of these signals can be interconnected with corresponding line of any Bus 1 - 4. Except Power
supplies, it is possible to connect L/H separately to different busses (for example CH-1 L to Bus 1 L and CH-1

MX2400 Programmer's Manual

H to Bus 3 H). Power supply L and H lines can be connected to Bus 1 - 4 only both at once.
Current measurement block:
I-MEAS (IM) to measure current of PS-1/2 using the external multimeter
IM block enables to route PS-1 or PS-2 current directly or through an amper-meter (I-MEAS lines). See

SW - main switch to put the
current directly or through the

SW-B - bypass switch, closed for
necessary time of during
switching the main switch SW
(=> current is not interrupted),
controlled automatically by the
hardware
The I-MEAS signal is not multiplexed to the main bus 1 - 4, it is connected always to both IM blocks (=
equivalent switches of current measure).
Typically, both L and H of any signal are connected to the same bus and because power supplies can be
connected only this way, we can simplify the schematic to following:

Any cross of any signal and bus represents a corresponding switch. For bus multiplex and multimeter signals
it is possible to connect L or H only.
5.3 Commands
Commands to control test-points and routing of Matrix. Chaining of commands is supported.
Tip
Routing commands can be copied from plugin's GUI control - both from MX card routing and also for Master
routing. The command below the routing schematic for every MX and routing card will configure the routing like
configured using the schematic.

of TP to/from HIGH bus. The "cset" does almost the same like "set", but "cset" disconnects all previously
connected TPs first.
Parameters
low
LN
[int]
TP number (1 to N) to be connected to LOW bus.
high
HN
[int]
TP number (1 to N) to be connected to HIGH bus.
Return value
No return value.
Examples
cset:10:15
Disconnect all TPs and connect TP10 to LOW and TP15 to HIGH bus.
set:10:15
Leave currently connected TPs and connect moreover TP10 to LOW and TP15 to HIGH.
clr:10:15
Disconnect TP10 from LOW and TP15 from HIGH bus. Any other connected TP is leaved untouched.
cset:l:10:12:14:h:15:17:19
Disconnect all TPs and connect TPs 10, 12 and 14 to LOW and TPs 15, 17 and 19 to HIGH bus.
clr:l:10:12:h:15:17
Disconnect TPs 10 and 12 from LOW and TPs 15 and 17 from HIGH bus.
clr:l:10:12:set:l:8:9
Chaining example. Disconnect TPs 10 and 12 from LOW and connect TPs 8 and 9 to LOW. Any other TP
is leaved untouched.
clr:*
clr:all
Disconnect all TPs from any bus.
Parameters
No parameters.
Return value
No return value.
5.3.2 route|croute (MX card routing)
route:
croute:<loc>{:<card-bus>}:<main-bus>
Interconnection of internal MX card's buses (or lines) to any main bus 1 - 4. The "croute" clears all previous
routing before applying new (like cset/set of test-point control). The "route" clears only settings of passed
main-bus.

MX2400 Programmer's Manual
19 FPC s.r.o. 2021Rev. 2021.4.22
The pair <card-bus>:<main-bus> can be several times in the one route|croute command - see examples.
Parameters
loc
#[int] or *
MX card location 1 to N. If number is passed, it must be
prefixed by a sharp-character (#).
To set routing of all MX cards, pass an asterisk (*) as a
location.
card-bus
[enum]
Card's internal bus or line:
al = A, low
cl = C, low
ah = A, high
ch = C, high
l = A + C, low (LOW lines of A and C)
h = A + C, high (HIGH lines of A and C)
a = A, low + high (both LOW + HIGH lines of A bus)
c = C, low + high (both LOW + HIGH lines of C bus)
ac = A + C, low + high (all card's buses)
If this parameter is not passed, the default is "ac" (all card
buses).
See MX card routing description for details about lines/buses.
main-bus
[enum]
Main bus:
b1 = Bus 1
b2 = Bus 2
b3 = Bus 3
b4 = Bus 4
H/L of main bus is defined by card-bus parameter. L of card-bus
is connect to L of main-bus (and the same for H).
Return value
No return value.
Examples
croute:*:b1
Clear all previous routing of all cards and connect both card's internal buses to main bus 1 for all cards.
This is the most used command for most of the systems.
AL AH CL CH
Bus 1
Bus 2
Bus 3
Bus 4

MX2400 Programmer's Manual
20 FPC s.r.o. 2021Rev. 2021.4.22
route:#3:a:b1:c:b3
Only for card at location 3. Clear previous routings of b1 and b3 and connect card's A bus (L + H) to main
bus 1 and card's C bus (L + H) to main bus 3. Previous routing to b2 and b4 (if exists) is leaved
untouched.
AL AH CL CH
Bus 1
Bus 2
Bus 3
Bus 4
5.3.3 route|croute (Master routing)
route:
croute:mux{:<main-bus>:<mux-ch0>{:<mux-ch1>:...:<mux-chN>}}
Interconnection of main bus and Connection card input/output signals.
Parameters
main-bus
[enum]
Main bus definition:
b1 to b4, bus 1 - 4, low + high
b1l to b4l, bus 1 - 4, low only
b1h to b4h, bus 1 - 4, high only
mux-ch
[enum]
Signal to be connected to the main-bus:
ch1 to ch4 or y1 to y4 (master card with older firmware
version accepts y1-y4 only), Bus Multiplex block (SW MUX
switches)
sens and meas, Multimeter block (SW MM switches)
ps1 and ps2, represents PS-1 and PS-2 PSU inputs, Power
supplies block (SW PS switches)
See Master routing description for details about blocks and
signals.
Return value
No return value.
