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.
