I just installed Windows 7 Professional in order to test ErosLink for the ET312 and discovered a few good things.
First, Windows 7 seems faster than Windows XP or Vista which is a cool “feature” of any new operating system.
Secondly, ErosLink works just fine under Windows 7. I used one of our USB to Serial adapters (with an FTDI chipset) and as soon as I connected it to my computer, Windows 7 discovered it and initially couldn’t figure out how to make it work. I opened the troubleshooter balloon that popped up and told the system to allow Windows to find the best driver for my device. It went out and did some searching and in a minute or so, installed the driver and presented me with a new COM port (COM3 in my case).
Installing ErosLink went smoothly also. I inserted the CD and Windows asked me what I wanted to do with it. I clicked on the default (Install) and the installer launched and in less than a minute, I had an ErosLink program installed on my computer, ready to launch.
I connected the USB to Serial adapter port to the included serial cable that comes with ErosLink and plugged the stereo plug into the Link jack of my ET312, then powered it OFF and back ON again. A fresh restart is important when connecting your 312 to ErosLink. Then I clicked the Start menu (lower left of window) and found ErosLink waiting as a recent application to click on. It discovered my ET312, synchronized to it and connected, giving me the status bar of options. From there, I downloaded a few user routines to the box and tried the interactive mode without any loss of connection or other issues.
So there we have it: ErosLink works under Windows 7 too! And if you’re having problems getting Windows to find the right driver, the manufacturer site has updates for our USB to Serial adapter.
I received an email from a customer today asking some questions about his new ET312, specifically why the battery level seems to fluctuate suddenly when the AC adapter is connected, and why the charge level seemed so low when he first turned it on.
The battery level displayed can be a little confusing. Here’s how it works.
When plugged into the AC adapter, the battery level displayed is higher since it sees the charging voltage being delivered to the battery via the charging circuit. It’s normal for the displayed value to increase to 99% as soon as the adapter is connected, but this isn’t really displaying an accurate battery charge level. In order to sense the battery voltage, the AC adapter needs to be disconnected before the ET312 is powered on. [Future idea: Maybe there should be a way of disabling the battery charging circuit during power-up in order to get a more accurate display of the battery level, with or without the charger being connected. Noted.]
The percent charge is also an approximate figure. It’s normal for our units to ship with a battery that is 50% – 75% or more charged when you first turn it on. For best results, connect it to the AC adapter and let it charge overnight to stabilize the battery level. Then make sure it gets connected to the charger at least once a month — or just leave it connected all the time. It won’t hurt the battery.
Don’t forget about the ET312 for 6 months and then expect the battery to have any life left in it. It will slowly discharge by itself so charging it routinely is the best course.
Let’s say you own one of the best erotic e-stim units out there: an ErosTek ET312B. Do you wish it could feel even smoother and have even more power than it does when you take it fresh from the factory box? Using the ET312′s Menu function, you can do both of these and so much more. I’ll show you how to increase the power range from the factory-default (Normal) to the maximum range (High) using the Menu key. Next I’ll show the steps that allow you to increase the maximum frequency to provide the smoothest waveforms possible. Finally, I will show the steps to save both of these changes into flash memory so that they remain even when the ET312 is turned off and back on again. And if you mess up and want to go back to factory-fresh, I have a bonus set of steps for you.
Let’s begin:
To change the power level:
You can increase the output frequency for smoother feeling outputs.
To save your custom settings for the next time (even after powering your ET312 off and back on):
That’s it! The ET312 Menu has a lot of things you can change. If you get confused or don’t like the output you’re getting, you can always reset your ET312 back to its factory-default settings.
I hope these steps help you get more from your ET312. If you have any questions or comments, feel free to leave a comment below or contact me at eric@erostek.com. You can see these steps and more in the ET312B User Guide.
You might be thinking of getting an ErosTek unit but wonder if your existing collection of electrodes and e-stim accessories are going to work. The short answer is: They Will. With the use of adapters (as needed), you can connect virtually any electrostim accessory to an ErosTek power unit. And most will just plug and play. But how do you know?
When you purchase an electrode accessory from our SexTek Online Store you will notice whether or not an adapter is needed on each product page. For the most part, all of our reusable electrodes come with an adapter included. The exception is our low-cost gel electrodes and a few separate electrodes that become part of a larger set. To be sure, just read the product page and you will see if you need an adapter that is not already included.
If you have electrodes from other manufacturers, there are some basic rules to follow. The main point to remember is that an ErosTek unit comes with leadwires that use a 4 mm banana connection. These plugs have a four-sided flat spring that compresses to make a tight connection with the mating jack. If your electrode has a 4mm banana jack (or “banana jack”), it will connect to an ErosTek unit without an adapter.
From Left to Right: 4mm banana plug, 2mm TENS plug
Some accessories have a small pin jack that is usually connected to a TENS unit. A TENS pin measures 2 mm (0.080″) in diameter. ”TENS” = Transcutaneous Electrical Nerve Stimulation and is a medical use of electro-stimulation for the reduction of chronic pain. Gel electrodes and some other toys have leads designed to be plugged into a TENS pin lead. For these toys, our Bananas to Pins adapter works perfectly in converting a banana plug (from an ErosTek unit) to the smaller TENS pin required by these toys.
Other manufacturers use a snap adapter connection, like the one on our ElectroBand and Dual E-Band. For these types of toys, our Banana-Snap adapter will convert a banana plug to a 4mm snap connection. Some PES electrodes use a pinch-type snap connector instead of our spring-loaded snap jack. If you need this particular type of snap connector, it’s easy to purchase one of their Umbilical Cords or regular leadwire sets directly from their online store. The plugs that connects to their power unit is the same plug used by an ErosTek unit, so their leadwires will plug directly into an ErosTek with no further adapting.
With the right equipment, it’s pretty easy to do electro-stim right the first time you try it. If you need any help in figuring out what you need, our Support Page is the place to go for email, chat or telephone support.

I’ve been a loyal customer for several years now (thanks for all the fun!). I was wondering if you or anyone you know has experience traveling on airlines with an ET312 unit and “accessories”?
Hello Tom,
Thanks for your email. I’m glad you’re enjoying e-stim and our products. I have traveled with my ET312 and ET232 [and ET302R remote] many times and in each case, I’ve carefully packed each in my checked baggage. I’ve heard of users carrying on their ET312 and explaining that it’s a test instrument used for home theater systems (or something similar). The agent usually asks for you to turn it on just to prove that it does something, but otherwise, passes it through with no problems. It’s a good idea to pack your accessories and electrodes separately if possible or just pack them together in your checked baggage. I’ve attended a variety of fetish events in the USA and other countries over the years with loads of e-stim and other gear and have never had a problem getting them through customs or domestic baggage inspectors.
I hope this helps!
I bag my accessories in opaque nylon bags like the ones found in your local hiking or camping store (I bought mine at REI) and stow them in my checked bag. This keeps the gear from getting separated during flight and seems to keep inspectors from noticing or handling my personal gear. The less shocked or interested they become when inspecting your bag – if they do – the better.
I remove the 9-volt battery in the ET232 and ET302R and make sure the power on my ET312 is turned OFF and packed securely so that it doesn’t get turned back ON during flight or handling. My Samsonite luggage has a zippered vinyl compartment attached to the inner front panel that accomodates my ET312 and keeps it from getting bumped around or having its power button pressed ON.
If you have any ideas regarding traveling with your e-stim gear, post your comments to this post and I’ll respond to them.
Safe Journeys!
