4. Operation
4.8.5. Control Protocols
Matrix routers can be controlled with multiple control protocols.
Lightware routers have a special protocol, but to inter-operate with
third-party devices, a secondary protocol is also provided.
AAAENAIONG!
Be aware that different control interfaces can be set
to use different protocols. D.g. Lightware protocol is set on Dthernet
interface while Protocol #2 is set on the Serial interface at the same
time. Lightware Device Controller software and the built-in website
works only with LW protocol (#1)!

INFO: The communication protocol of the USB interface (Lightware
protocol) cannot be changed.
The currently used protocol can be viewed or changed any time on the
matrix front panel or by protocol commands.
Changing (displaying) the Current Protocol on the Front Panel
Step 1. Switch the router to TAKE mode; if AUTOTAKE mode was active
press the TAKE button for 4 seconds. (light will go off)
Step 2. Press Control Lock button for 3 seconds (it lights in up red
continuously)
Step 3. Press and keep pressed the Output Lock button, the button will
light in red. Now the active protocols for the Serial and the
Dthernet ports are displayed (view protocol):
a) One source button lights up according to the current protocol on
the Serial port:
Lightware protocol active on Serial
– Source#1 lights:
– Source#2 lights: Protocol#2 is active on Serial
b) One destination button lights up according to the current protocol
on the Dthernet port
– Destination#1 lights: Lightware protocol active on Dthernet
– Destination#2 lights: Protocol#2 is active on Dthernet
c) The LCD on the front panel shows the active protocols for each
interface as well.
Step 4.
a) Release the Output Lock button to keep the current protocol.
b) If you want to change the protocol on any interface, keep the
Output Lock button pressed, and press the desired Source or
Destination button, accordingly to the new protocol for that
specific interface.
Step 5. If the control protocol for any interface has changed then a
beep will sound to notify the change.

Connect to the matrix through any control interface, then use the
commands described in the Changing the Control Protocol
4.9. Error Handling
The MX-CPU2 can detect and log many system events. Dvery log entry
gets a time stamp based on the CPU real time clock. These events are
categorized by levels.
Level Description
Notice Not an error. Initialization information.
Warning Possible problem without influencing normal operation.
Matter Problem that may lead to further errors.
Error Serious error. Must report to support.
Fatal Fatal error. Normal operation is not possible.
The matrix router saves error logs on the built-in micro SD memory
card. These log files can be downloaded and viewed with the controller
software.
The error log entries have an error level, time, error code, error parameter,
processor task identifier, occurrences and extra information.
The device creates a new error log file every time it is started except if
there is already a log file created for that day. The software allows to
select only months and days which have a log.
The matrix can indicate if an error occurred in several ways:
▪ Show alert on the front panel LCD
! ATTENTION !
Please check log in
Device Controller
ENTER=View ESC=Exit
▪ Send protocol messages when errors occur. The levels for which
this immediate message is sent out can be changed by protocol
command.
▪ Indicate with ALDRT LDD and SMPTD alarm output on the MX-
CPU2 board. If the Alarm LDD was triggered it remains lit until
the frame is rebooted.
The default levels which trigger an alarm for the specific method are
shown below:
section.
Level Name
0 NOTICD
1 WARNING
2 MATTDR
3 DRROR
4 FATAL

INFO: This log can contain NOTICEs and WARNINGs under normal
operation. These entries do not mean that there is any problem with
the matrix!
Low Battery Alert
The warning shows that the battery on the CPU board is exhausted
or not inserted. The function of the battery is powering the real time
clock when the frame is powered down. The low battery does not
affect normal operation of the matrix. However the error log will not
have correct time stamps.
Replacement Steps
Step 1. Switch off the matrix and take out the MX-CPU2 board. Locate
the battery holder. Check if the battery is contacting well in the
holder.
Step 2. Take the battery out firmly taking care not to bend the
spring contact upwards. Bend the spring contact a little bit
downwards to ensure good contact.
Step 3. If the battery is exhausted, replace with lithium button battery
type CR2032.
