VS-88H2 – Connecting VS-88H2
Connecting to VS-88H2 via RS-232
You can connect to the VS-88H2 via an RS-232 3-pin Terminal Block Connector using, for
example, a PC.
To connect to the VS-88H2 via RS-232:
• Connect the RS-232 rear panel port on the VS-88H2 unit via a 9-wire straight cable (only
Tx to pin 2, Rx to pin 3, and G to pin 5 need to be connected) to the RS-232 9-pin D-sub
port on your PC.
• Pin 2 to the TX pin on the VS-88H2 RS-232 terminal block
• Pin 3 to the RX pin on the VS-88H2 RS-232 terminal block
• Pin 5 to the G pin on the VS-88H2 RS-232 terminal block
Connecting VS-88H2 via the ETHERNET Port
You can connect to the VS-88H2 via Ethernet using either of the following methods:
• Directly to the PC using a crossover cable (see Connecting the Ethernet Port Directly to
a PC on page 10).
• Via a network hub, switch, or router, using a straight-through cable (see Connecting the
Ethernet Port via a Network Hub or Switch on page 12).
If you want to connect via a router and your IT system is based on IPv6, speak to your IT
department for specific installation instructions.
Connecting the Ethernet Port Directly to a PC
You can connect the Ethernet port of the VS-88H2 directly to the Ethernet port on your PC
using a crossover cable with RJ-45 connectors.
This type of connection is recommended for identifying the VS-88H2 with the factory
configured default IP address.
After connecting the VS-88H2 to the Ethernet port, configure your PC as follows: compatible
1. Click Start > Control Panel > Network and Sharing Center.
2. Click Change Adapter Settings.
3. Highlight the network adapter you want to use to connect to the device and click Change
settings of this connection.
The Local Area Connection Properties window for the selected network adapter appears
as shown in Figure 10.
