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 r outer, 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

1. Right-click the My Network Place s icon on your desktop.
2. Select Properties.
3. Right-click Local Area Connection Properties.
