Troubleshooting
To troubleshoot the serial connection, send the <Ctrl + D> character to the serial port. The
router should respond with something like 72 or 75 with some special characters at the
beginning and at the end. The first character has ASCII code 0 × 15 (NAK) and the last one is
0 × 04 (EOT). If you see something like that, then you can assume that the serial port is
configured properly. To troubleshoot the Ethernet connection, try pinging the router first and
if you succeed then try connecting to the router via telnet. To end the telnet session, type
logout .
Lightwave Matrix-Hub 1000
The Matrix-Hub can be connected to the app server by a standard RS-232 cable. The settings
of the serial port are displayed on the router’s screen. The Matrix-Hub router requires that the
user should log on from the serial port. In order to automate this, set the name of the physical
router to the password. The default password is
mh1 . If you want to do all switches in RS-422
mode, then the name of the serial level should contain the string 422 , for example, you can
name it Serial-422. If that string ( 422 ) is not found, then all the switches are done in RS-232
mode.
It is impossible to do both 422 and 232 switches. The system always assumes that the Video
level has frame ID 1, the K/M level has frame ID 2 and the serial level has frame ID 3. Note that
the K/M switch takes about 0.5 seconds, so there is a noticeable delay. The K/M and serial
connections are
unicast (that is, you can connect one source to only one destination
although a bug in Matrix-Hub firmware sometimes allows you to do that). It means that if the
source was connected to a destination, and then user connects it to another destination, the
first destination is disconnected automatically. A video source can be connected to several
destinations simultaneously.
