This product can be purchased either with a 30-pin connector (iMSO-204) or a lightning connec-
tor (iMSO-204L). Both products function exactly the same. The only difference is the connector.
iMSO-204 has the 30-pin connector and iMSO-204L has the lightning connector.
The Quickstart Guides for each product are highlighted below.
First, here is the lightning version:

1.20 SAFETY
The maximum voltage limit for the analog probe in 1x mode is -8v / +13v, and the maximum
voltage limit in 10x mode is -40V / +40V. The maximum voltage limit for the digital channels
is -.0.5v to +7v. Oscium is not held liable for usage outside of these limits.
1.30 Compatibility
1.31 Hardware
Oscium has two versions of the same hardware with the only difference being the connector:
iMSO-204, which has a 30-pin connector & iMSO-204L, which has a lightning connector. Here
are the specific Apple devices that are compatible with each piece of our hardware:
iMS0-204L (Lighting Version) iMSO-204 (30-pin version)
iPod touch (5th generation) iPod touch (4th generation)
iPhone 5S, iPhone 5C, iPhone 5 iPhone 4s, iPhone 4, iPhone 3GS
iPad (4th generation), iPad Mini iPad (3rd generation) iPad 2, iPad
*With an Apple-approved lightning adapter, iMSO-204 will also work with the newer, lightning
models. But the same is not true in reverse. The lightning adapter will not enable iMSO-204L
to work with 30-pin iOS devices.
1.32 Software
Although Oscium has two versions of hardware (iMSO-204 & iMSO-204L), there is only
one app and it is called iMSO2. iMSO2 is free to download in the App Store. Upon plugging
our hardware into your iOS device, the downloaded app will recognize which version of the
hardware is in use. The app functions exactly the same regardless of which hardware is in use.
Please keep in mind that the:
Required OS is 5.0 or newer
Oscium also has another app called iMSO. This app only works with iMSO-104 hardware. For
iMSO-204 & iMSO-204L to work, please download iMSO2.

1.40 Tool Tips
Although having a manual is nice (and if you’re reading this, you probably agree), it is even
better when there’s help built into the app itself. Here is a screenshot of some of the tool tips
we’ve built into the app (this picture is found on iOS 7 software and newer):
