EA-1 Ethernet Adapter


Ethernet Adapter

The EA-1 Ethernet Adapter turns your sensor into an Ethernet Laser Power Meter. Features include:

  • From sensor direct to Ethernet with no PC connection
  • Power direct from the Ethernet bus
  • Supports thermopile, photodiode and pyroelectric smart sensors
  • PC application software package included
  • Allows remote monitoring via Telnet, HTTP and UDP protocol

How is the EA-1 Ethernet Adapter powered?

The EA-1 can be powered directly from the Ethernet bus if PoE (Power over Ethernet) is available. If not, it can use a 12 24 VDC standard Ophir power supply.


What is included in the box with the EA-1?

Besides the Ethernet Adapter itself, the package also includes:

  • Ethernet cross cable
  • USB-A to USB-Mini-B
  • 12 VDC power supply
  • CD (for PC application, manual, and drivers for using USB virtual COM port)
  • Brackets, screws, and an Allen wrench for mounting

How can I control the sensor via the EA-1 device?

There are three ways to connect to the EA-1 adapter:

  1. Telnet:
    Establish a connection using the IP address of the EA-1. The host (e.g., PC) is considered the “client,” while the EA-1 is the “server.”
  2. HTTP:
    The IP address of the EA-1 should be entered into a regular web browser. This will show a top-level “web-page” with several buttons for accessing lower level pages. Commands can also be sent directly with the HTTP protocol. Client and server status are the same as above (Telnet).
  3. USB virtual COM port:
    For configuration and initialization only. This can be used to set the IP address for the first time or switch between dynamic and static IP address modes.

More details can be found in the EA-1 manual.


Can I write my own software to work with EA-1 Adapter?

Yes. See chapter 6 of the manual.


What sensors does the EA-1 Ethernet Adapter work with?

Thermal, photodiode, and BeamTrack (power/position/size) sensors: standard and smart plug (“-SH”) OEM sensors. Pyroelectric energy sensors are not compatible at this point. (Note the PC application only supports thermal and PD sensors, but BeamTrack can be controlled by using commands.)


How do I set the IP address of the EA-1 Ethernet Adapter?

The device is shipped with these defaults:

IP Address ....................................
Subnet Mask .................................
Default Gateway ............................
User Device Name ......................... (blank)
IP Address allocation ...................... static (DHCP disabled)

The IP address can be set via HTTP, Telnet, USB virtual COM port, or the “OphirEthernetApp” software. See Chapter 2 of the manual for step-by-step instructions for each method.

  • StarLab

    The StarLab application together with an Ophir meter turns your PC or laptop into a full-fledged laser power/energy meter. Supports most Ophir laser power/energy sensors. Up to 8 sensors can be displayed at once on one PC. By using the Ophir COM Object, you can control the device from your own application. Supports the StarBright, StarLite, Juno, Nova II, Vega, Pulsar-1/2/4, Quasar, EA-1 and USBI devices.

Besides their use as stand-alone, fully featured laser power/energy meters, Ophir devices are easily incorporated into larger end user applications. This allows system integrators to leverage Ophir's excellence in measurement capabilities with legacy analysis packages.

Ophir provides all the details for integrating the EA-1 device in the EA-1 user manual.


System Integrators will need the following components:

  • Standard mini-B USB cable (P/N 7E01217) for use with the EA-1 device (included).
  • Ethernet Cross Cable (P/N 7E01192) for use with the EA-1 device (included).
