Checking network cable connections

<Checking types of cables>

•Check that the twisted pair cables for 10BASE-T or 100BASE-TX are used.

•If the DS-L1 is connected to a LAN via a hub, check that straight cables are used.

•If the DS-L1 is connected directly to a PC without going through a hub, check that crossed cables are used.

<Checking hub connections>

See the instruction manual supplied with the hub for details, and follow the description written in it.

•Do not connect the DS-L1 to the Uplink. Be aware that Uplink on some hubs is indicated as “MDI,” “≡,” “Uplink-1 ⋅,” “1-1 ⋅” or “8-8 ⋅.” Also, if a hub has cross and straight ports, caution must be exercised.

•There is a limited number of useful ports on a hub. Be careful when connecting to an empty port, because doing so could exceed the limit.

Checking the set values

<Settings on the DS-L1>

•Make network settings in Network Settings of the DS-L1 SETUP menu (e.g., Enable Network or IP Address).

•Always be sure to make gateway settings if data communication between different network groups is to be performed (e.g., sending or receiving data to and from a distant place of business).

<Settings on a PC>

•When connecting from a PC that is not connected to a LAN, check the network settings on the PC first.

•Set the IP address and other information specific to the PC.
