If an item is missing or damaged, call DATAQ Instruments at 330-668-1444. We will guide you through the appropri- ate steps for replacing missing or damaged items. Save the original packing material in the unlikely event that your unit must, for any reason, be sent back to DATAQ Instruments. -
Page 14: Connect The Instrument To Your Computer
All DI-4730 instruments are shipped DHCP-enabled. We recommend you setup a DHCP reservation on your network for your data acquisition applications. Find the MAC address of your DI-4730. The device MAC address is printed on the bottom label of the device: Login to your Router and ensure the DHCP server is enabled. - Page 15 DI-4730 Hardware Manual If your device is not discovered in WinDaq Dashboard, connect it to your computer via the USB cable and configure the Ethernet settings to allow for DHCP. If the device is available in WinDaq Dashboard but you cannot run WinDaq Acquisition software, you may have the application blocked in Windows Firewall.

Page 22: Control "Button" Operations
Switching between LibUSB and CDC Modes The native communication mode of DI-4730 instruments is LibUSB but it can be switched to the USB CDC (Communication Device Class). CDC mode allows the USB port of DI-4730 devices to appear like a traditional RS- 232 port, which is common across most operating systems and development languages. -
Page 23: Apply Ethernet And Stand-Alone Configuration To Device
Power must be applied with the included power adapter or with an alternate appropriate source (9-36VDC, 15 watts max). Alternately you may power the device with a Power over Ethernet (PoE) switch. Power Switch Power the DI-4730 on/off using the power switch. Connecting Digital Input Signal Leads Connect signal leads to the DI-4730 digital inputs: Insert the stripped end of a signal lead into the desired terminal directly under the screw. -
