Advantech HMI-640S user manual Networking via LAN, Connect or disconnect any cable

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.
