Connect the mar345-scanner and/or dtb to the Ethernet card and power them up. To check availability on the

network, type:

ping 192.0.2.1 (check availability of mar345 detector)

ping 192.0.2.3 (check availability of dtb)

If the scanner is accessible, ping comes back with:

PING mar345 (192.0.2.1): 56 data bytes

64 bytes from 192.0.2.1: icmp_seq=0 ttl=255 time=1 ms

If ping comes back with:

ping: mar345: Unknown host

ping: dtb: Unknown host

then, mar345 and/or dtb has not been inserted into le /etc/hosts (see above).

If ping hangs with:

PING mar345 (192.0.2.1): 56 data bytes

PING dtb (192.0.2.3): 56 data bytes

then the reason might be:

a) the network interface has not been congured correctly

b) the scanner or dtb are not turned or are not yet ready to listen

c) there is a problem with the Ethernet cable

d) there is a problem with the hub (check power cable!)

e) a regular RJ-45 cable has been plugged into the Uplink port of the hub

f) a cross-over cable has been plugged into any but the Uplink port of the hub

g) there is a problem with the scanner or dtb itself

7.4 How to connect RJ-45 cables to the hub

A hub allows two or more computers to talk to each other. There are two types of twisted pair Ethernet cables with RJ-

45 connectors: regular ones and cross-over cables. Crossed cables must be used to directly connect two computers to

each other without a hub in between. I.e. you can use a crossed cable to connect the Ethernet card of your computer

and the mar345-detector with no hub in between. If there is hub, please note, that most hubs feature 4 or more regular

ports and one “Uplink” port. You can connect regular cables to the regular hub ports (i.e. mar345-detector, dtb and

computer). Alternatively, you may use a crossed cable to connect the computer or mar345 or dtb to the “Uplink” port

of the hub. All other combinations are not going to work.
