HMI-640S User's Manual
6.1 Introduction
The HMI-640S is designed as a networking gadget that readily
connect itself to the host PC either via existing LAN or a RS-232
interface. Its network capability makes it nothing less than a powerful
platform for any application that demands networking communication
or remote file transfer. The following sections will guide you through
the networking steps for HMI-640.
6.2 Networking via LAN
Ethernet has been so predominant in LANs that we come to regard it
as the de facto standard for network communication within LANs.
The HMI-640S takes advantage of Ethernet networking to connect to
a host PC for convenient network communication and file transfer.
Please follow the procedure described below to set up network
connection between HMI-640S and host PC via Ethernet network:
1. Before connecting to LAN, first make sure you have properly set
up your host PC on a Ethernet LAN running TCP/IP networking
protocol. If you have not installed the TCP/IP network protocol on
your host PC, you must install it first before joining the host PC to
Ethernet LAN.
2. Make sure your HMI-640S is running an OS that has its TCP/IP
network protocol enabled.
Note: If you use a CompactFlash drive which is prein-
stalled with Windows CE or other network-enabling
software, your HMI-640S is ready for TCP/IP
networking. You don't have to install other compo-
nents to run TCP/IP networking.
3. Disconnect any power source from your HMI-640S.
Note: Be sure to power off the HMI-640S before you
connect or disconnect any cable.
