How can I tell my version number?

If you still have the retail box (black box with picture on the top of the module), you can look on the "spine" and there should be a sticker that has some numbers in the format of:

Vx.yyRz

The first number is the major version, the second is minor version, and the "Rx" section is just a build number.

FOR EXAMPLE:

V8.3R1 is Version 8, minor version 3, Release(build) 1

The module will do the following if you plug it in, or whenever it wakes from sleep:

1. The LEDS will cycle end to end as the module performs it's internal diagnostics
2. Once they complete, it will BLINK the LED on the far right the number of times for the major Version number
3. The LED right next to that will BLINK the minor version.

In the above 8.3 version example, you would see:

1. FIRST LED will blink EIGHT (8) times
2. After #1 completes, the SECOND LED will blink THREE (3) times
