FAQ
How is the EA-1 Ethernet Adapter powered?
What is included in the box with the EA-1?
How can I control the sensor via the EA-1 device?
There are three ways to connect to the EA-1 adapter:
- 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.” - 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). - 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.
CloseCan I write my own software to work with EA-1 Adapter?
What sensors does the EA-1 Ethernet Adapter work with?
Thermal, photodiode, and BeamTrack (power/position/size) sensors; pyroelectric and photodiode energy sensors; standard and smart plug (“-SH”) OEM sensors. (Note that the OphirEthernetApp PC Application does not support BeamTrack, but BeamTrack can be controlled by using commands.)
CloseHow do I set the IP address of the EA-1 Ethernet Adapter?
The device is shipped with these defaults:
IP Address .................................... | 10.0.0.2 |
Subnet Mask ................................. | 255.255.255.0 |
Default Gateway ............................ | 10.0.0.1 |
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.

What is Ophir Statement of Volatility of Memory for EA1- Ethernet Adapter
I need to embed the EA-1 Adapter into my laser system; can it be controlled from a PLC?
Yes it can. You can find a good set of guidelines in the following article: Tips using the EA-1 with a PLC. Complete instructions can of course be found in the EA-1 User Manual.

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 Ariel, Centauri, StarBright, StarLite, Juno, Juno+, Juno-RS, Nova II, Vega, Pulsar-1/2/4, Quasar, EA-1 and IPM sensor devices.

System Integrators
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).

Laser Measurements in Materials Processing: How and When They Absolutely, Positively Must Be Made
How do I know what range, or scale, to set my power/energy meter to? And what happens if I go over range?
Each given range represents one level of gain of an internal amplifier. The electronics, as always, have a limited Dynamic Range. If the measured signal is too low, in other words near the bottom of the range, then it may be lost in the noise and the reading will be inaccurate and noisy. If it’s too high – there may be saturation issues. To give an instrument a usefully wide dynamic range, multiple scales or ranges are used. Switching from range to range can be automatic (“Autorange”), or manual. Autoranging simply starts automatically at the least sensitive range and works its way down the ranges, sampling the signal as it goes, till it finds a range at which the signal is properly detected. Note, by the way, that only in POWER mode is Autoranging available. If we are working in Single Shot Energy mode, there is no Autoranging – simply because when we are measuring a single pulse, the instrument has no opportunity to work its way down the ranges as in Power mode.
