To connect to the VP-88K via RS-232 as illustrated in the example in
Figure 7 ):
• Connect the RS-232 9-pin D-sub rear panel port on the VP-88K unit via a
9-wire straight cable (pin 2 to pin 2, pin 3 to pin 3, pin 5 to pin 5) to the
RS-232 9-pin D-sub port on your PC
6.3 Connecting to the VP-88K via RS-485
You can operate the VP-88K via the RS-485 port from a distance of up to 1200m
(3900ft) using a PC equipped with a card that provides an RS-485 port.
To connect a PC or controller to the RS-485 port on the unit:
1. Wire the RS-485 port on the VP-88K to the RS-485 port on the controller as
follows:
 Connect the A (+) pin on the RS-485 port of the PC to the A (+) pin on
the RS-485 port on the rear panel of the VP-88K
 Connect the B (–) pin on the RS-485 port of the PC to the B (–) pin on the
RS-485 port on the rear panel of the VP-88K
 Connect the G pin on the RS-485 port of the PC to the G pin on the
RS-485 port on the rear panel of the VP-88K
2. Set the DIP-switches (see Section 6.5
3. Terminate the RS-485 line on both the VP-88K (set DIP-switch 1 to ON) and
on the controller.
) so that the Machine number on the
VP-88K is any number between 2 and 16.
6.4 Connecting to the VP-88K via the Ethernet Port
You can connect the VP-88K via Ethernet using either of the following methods:
• Direct connection to the PC using a crossover cable (see Section 6.4.1
• Connection via a network hub, switch, or router, using a straight-through cable
(see
)
Section 6.4.2
Note: The following instructions are valid only if your PC uses a fixed IP address.
If your PC receives an IP address from a DHCP server, consult your IT department
regarding a suitable IP address.

6.4.1 Connecting Directly via the Ethernet Port
You can connect the Ethernet port of the VP-88K to the Ethernet port on your PC
via a crossover cable with RJ-45 connectors.
This type of connection is recommended for identification of the factory
default IP Address of the VP-88K during the initial configuration
To connect the VP-88K directly to a PC using a crossover cable:
1. Using a crossover cable, connect the VP-88K to the PC via the Ethernet port
on both units.
