This guide describes how to use the SH6850 shielded cable to connect either a 68-pin MIO
Series board to a 50-pin MIO accessory or a 50-pin MIO Series board to a 68-pin MIO
accessory. In this guide, the AT-MIO-16, AT-MIO-16F-5, AT-MIO-16X, NB-MIO-16, and
NB-MIO-16X are referred to collectively as the MIO-16 Series boards. The newer MIO-16E
Series boards include the AT-MIO-16E-2 and the AT-MIO-16XE-50.

Introduction

The SH6850 shielded cable is a 1, 2, 5, or 10 m round cable, which has a 68-pin female
connector at one end and a 50-pin female connector at the other end. The SH6850 shielded cable
kit also includes a 3 in. ribbon cable and replacement brackets for the 50-pin AT-MIO Series
(AT-MIO-16, AT-MIO-16F-5, and AT-MIO-16X) and NB-MIO Series (NB-MIO-16 and
NB-MIO-16X) boards. The SH6850 shielded cable brings the pinout of your MIO Series board
I/O connector, which has either 68 or 50 pins, to the MIO accessory I/O connector, which has
either 50 or 68 pins.

  • Page 3 Connecting a 50-Pin Board to a 68-Pin Accessory Bracket Replacement Before you install the SH6850 to a 50-pin MIO board and a 68-pin MIO accessory, you must replace the bracket of your MIO board with the appropriate bracket from the SH6850 kit, unless your MIO board already has a bracket with a grounding strap tab.
  • Page 4 5. The 50-pin I/O connector on your MIO board may have small plastic key inserts installed for mating with military polarized connectors. Because these keys are incompatible with the 50-pin connector on the SH6850 shielded cable, you must remove them. The 50-pin SH6850 connector has a center polarization bump that prevents you from inserting the connector upside down.
  • Page 5 7. Install the new bracket by aligning the bracket with the holes in your MIO board and screw in the two mounting screws. Now you are ready to connect the SH6850 shielded cable to a 50-pin MIO board and a 68-pin accessory.
