Measurement Computing WebDAQ 316, User Manual

Se ng up the WebDAQ

Connec ng to a local area network

The WebDAQ requires a TCP/IP connec on to a network or the Ethernet port of a computer. A standard

Ethernet cable is shipped with the device. The WebDAQ IP address type is set by default for DHCP/Link-Local.

When connected to a network, the device first a empts to receive an IP address from a DHCP server. If this

fails, a link-local address is used. Use of a sta c address requires configura on via the web interface. The IP

address iden fies the WebDAQ on the network, and is used to access the web interface.

Connec ng to a network with DHCP enabled

Connect one end of the Ethernet cable to the connector on the WebDAQ rear panel, and connect the other end

to a 10Base-T or 100Base-TX compa ble Ethernet port, hub, or switch.
Once the device is detected, DHCP assigns an address. A different address may be assigned each  me the

hardware is connected to the network.

WiFi support

A er successfully configuring a wired connec on, you can use the web interface to configure the

WebDAQ for wireless communica on. Refer to the 

Configuring the WebDAQ for wireless

communica on

 sec on for more informa on.

Connec ng directly to a PC

Connect one end of the Ethernet cable to the connector on the WebDAQ rear panel, and connect the other end

directly to the Ethernet port on a PC. The WebDAQ a empts to communicate with the host PC using

169.254.100.100 – the link-local address stored on the device. The host PC may accept this address or use a

different address. The link-local address is valid only for communica ons between the WebDAQ and the host PC

to which it is connected.

Connec ng the external power adapter

Connect the network cable before connec ng to external power

Connec ng to the external supply before installing on a network results in the device a emp ng to

auto-nego ate a network address before one is available.

Connect the adapter to the power connector labeled EXT PWR on the device rear panel, and plug the AC

adapter into an electrical outlet.
Press the POWER bu on. The POWER LED on the rear panel turns yellow as the hardware starts up, and green

when it is ready for use.
