6.2 Controlling the PL-50 via the Ethernet Port
You can connect the PL-50 via the ETHERNET in the following ways:
• For direct connection to the PC, use a crossover cable (see section 6.2.1 )
• For connection via a network hub or network router, use a
straight-through cable (see section 6.2.2 )
6.2.1 Connecting the ETHERNET Port Directly to a PC (Crossover Cable)
You can connect the Ethernet port of the PL-50 to the Ethernet port on your
PC, via a crossover cable with RJ-45 connectors.
This type of connection is recommended for identifying the PL-50
with the factory configured default IP address
After connecting the Ethernet port, configure your PC as follows:
1. Right-click the My Network Places icon on your desktop.
2. Select Properties.
3. Right-click Local Area Connection Properties.
4. Select Properties.
The Local Area Connection Properties window appears.
