Frequently Asked Technical Questions

Can I use Minicom/Linux to communicate with a PIES or is Windows necessary?

• Minicom/Linux will work for communicating with the IES to set up missions and offload data. The Motocross windows software is only necessarily for performing firmware updates to the IES’s computer. In general the IES can be configured with any terminal emulator program and data can be offloaded by any software supporting the YMODEM protocol.

Which IES components contain oil?

• The pressure sensor and the acoustic transducer both contain oil. But the oils are distinctly different. The pressure sensor has a silicone based oil that is clear and very slippery. It has no odor. The acoustic transducer oil is castor oil which is yellowish and slightly sticky. It has a mild odor.

How is the current meter attached to the IES?

• There are two parts to the current meter mechanical connection. One is a reuseable bolt for spindle endpiece (AADI P/N 0964172) and the other is a cotter pin (AADI P/N 0660003). Replace the cotter pin (3/16″ diameter x 1 1/4″ long, 18-8) after each deployment. Contact AADI for replacement parts.
