Scroll to the bottom if you want to get in touch, but here's a quick overview of frequently asked questions about tripwire.
What exactly does tripwire do?
Our device makes a passive connection to the supervisory functions on the MRI, reads the magnet data, and sends it to our server for further processing. It does not take any direct action on the system except polling the MSUP for data.
How much do these units cost?
Free with a 24-month service contract, or you can use the pay-as-you-go option, Use the order page to get in touch.
How much do new users cost?
Nothing. You can add as many users to your group as needed.
What happens when I terminate an account?
If your tripwire unit gets turned off, it stops reporting. You can keep your data on our server for historical purposes at no cost, or we can delete it upon your request. You do not need to return any hardware.
Can I reuse a tripwire on another system?
Yes. What we do is archive your old data and assign your unit a new reporting identity.
What's required on my end?
You need a persistent internet connection so tripwire can “call home” every 30 minutes and update our server. The tripwire server will reside in your equipment room (110V connection) and connect to the MSUP either in the equipment room or through the penetration panel (filter and cables supplied).
Do you monitor my tripwire units?
No, we don't in general. We do keep an eye on who's responding (and not), and we may get in touch with you directly to try to help resolve issues, but we do not read your reports as a rule. The sole exception is if we are expanding services and want to make sure the new features work on a particular system type. Only in this case is it possible that we may load one of your server profiles — to check if a new feature is going to work properly when we update your account. Usually, we would do this on a test server with a copy of the tripwire database.
Why would I want to set an alert?
The main purpose of tripwire is to tell you when you have a problem. You can do this passively where the server waits for you to come check on things, or actively (recommended) where the server tells you when a monitored parameter exceeds a threshold. The latter is far superior because you're not bothered when everything is OK, but you are are alerted immediately if something is not right. Because tripwire checks in every 30 minutes, you are going to probably want to set a minimum interval between alerts so you don't get a text twice an hour.
Can I set multiple alerts on the same parameter? Why would I want to?
Yes you can. The reason why you'd want to is this: tripwire lets you set multiple alarms with independent thresholds and repetition. For example, you might want to know once a week (gentle reminder) if the helium level drops below 60%, but every 24 hours (strong reminder) if it drops below 45%. All you need to do is program two alerts on the same parameter (helium level) but with different trigger levels and repetition frequencies.
Are there any HIPPA considerations?
Absolutely not. There's no possible connection to anything that can access patient data.
Can you access our systems?
Absolutely not. We can access the tripwire server itself so we can reset it and make updates as needed, but there's no possible path to further areas in your system.
tripwire™ terms
Account
A customer account with Simplexable, used to associate billing services and users.
Group
The Tripwire™ software allow you to gather sites into functional groups. You can assign users to specific groups — limiting their access to a subset of your sites, or grant access to all sites by putting a user in your primary group. A single site can only belong to one group, but all of your groups belong to your account (see above).
RDU (aka Tripwire™ unit)
A single hardware device (mini-PC), supplied by Simplexable, that runs our code on top of Linux. This device connects to your MSUP (see above) and reports results to our servers for interpretation. The acronym RDU stands for Remote Diagnostic Unit.
Server
The backend of the Tripwire™ system is a cloud-based set of software that reads input received from the RDU, parses it into test results, stores them, and generates alerts as needed.
Simplexable.is, LLC
That's us :-). We provide a number of software products including the Tripwire™ system you are reading about now. We are responsible for design and assembly of the RDUs, operation of the backend server that reports results and alerts to you, and technical support for our users.
Site
A unique Tripwire™ reporting account. A tripwire unit (see "RDU") can be repurposed to report on different magnets, but each set of magnet-specific data is known as a discrete site. For the sake of simplicity, Tripwire #1 is connected to and reports on this magnet and Tripwire #2 is connected to and reports on that magnet.

It's possible to reassign an RDU if no longer needed on a magnet. We give it a new site ID and profile (no cost to you), you connect it, and it's now reporting as a new magnet. In this case, we do keep your original site data, but the site is no longer active and does not generate any alerts.

It's also possible to have a single RDU report on multiple sites in warehouse storage environments. Contact us for details.
User
A discrete user tied to a specific customer account. There's no cost or limit on the number of users tied to an account.
