DESCRIPTION
This MMU II controller is designed to function with the transceiver RS‐232 serial
ports to control the dialing and text messaging of a transceiver so equipped.
The MMU II is a POTS (Plain Old Telephone System) telephony device that interfaces
a 2‐wire POTS system such as a satellite transceiver to 4‐wire aircraft audio panel.
A 2x16 VFD display, rotary knob/push‐button and 12‐digit keypad provide the user
interface. Phone functionality is supported via direct keypad dialing as well as pre‐
configured phone numbers via a menu or speed dial button. In addition the MMU II
serves as a messaging terminal providing pre‐stored or freeform text messaging
through a proprietary RS‐232 serial interface. Messaging is supported on both the
2x16 character display as well Wi‐Fi devices via the built‐in Wi‐Fi support. An
internal Wi‐Fi antenna is provided and an optional external antenna may be used.
Note: Default Wi‐Fi channel is set to 6 with a Frequency of (lower/Center/Upper):
2.426/2.437/2.448 GHz. The Wi‐Fi link will be available inside the fuselage.
