9. Troubleshooting
9.1. General problems
Check the router
Check whether the router is properly powered and whether CPU LIVE LED is
blinking. Try performing a reset through the controller software, or unplug and
reconnect the rout
er‟s power cable.
9.2. Serial connection problems
Check the protocol
Check whether the proper protocol is selected (see section
about
). Select Protocol #1 in order to use the matrix
with the controller software.
Check the cable and software settings
Check whether your null-modem cable is properly connected. In most cases there
are more COM ports present in the operating system. Please verify the connection
settings of your software. The router communicates with
9600
Baud,
8
data bit,
N
o
parity,
1
stop bit.
9.3. TCP/IP connection problems
Check the LAN cable type
If you connect the router directly to your computer, you must use a cross-link cable.
If the matrix is connected to an Ethernet hub, switch or router, you have to use a
straight patch LAN cable.
Check the network connection
The computer and the router have to be in the same network. If your computer has
multiple network connections (for example WiFi and LAN connections are used
simultaneously), check which network the router is connected to. The appropriate
Ethernet interface has to be selected in the Find dialog box of the Matrix Controller
software (see section
4.2 Establishing the connection
on page
).
Check the IP settings
If you connect the router directly to your computer
, you have to set the router‟s IP
address manually, since in this case there is no DHCP server that could assign an
address to the matrix.
If the IP address is set manually, check if there is an IP address conflict. If there is
a DHCP server on the network, try to set the matrix to DHCP mode. See section
about how to reset the IP address with the front panel buttons on page
Check
whether your computer‟s firewall blocks the selected port.
