11. Troubleshooting
11.1. 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
router's power cable.
11.2. Serial connection problems
Check the protocol
Check whether the proper protocol is selected (see section 8.1 about changing protocols
on page 100). Select Protocol #1 in order to use the matrix with the controller software.
Check the cable
Check whether your serial cable is properly connected. A straight thru male-female cable
is needed for connecting the matrix to a computer's COM port.
Check software settings
The router communicates by default with 57600 Baud, 8 data bit, No parity, 1 stop bit.
The baud rate can be changed and checked on the front panel LCD menu.
Check if the correct COM port is selected in the computer for the connection.
11.3. 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 6.2 Establishing the connection on page 64).
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 5.5.3
about how to reset the IP address with the front panel buttons on page 61.
The matrix accepts LAN connection on the 10001 TCP port. This can be changed or
checked on the front panel LCD menu.
Check whether your computer's firewall blocks the selected port.
