EFIS Extenders and Accessories

I/O Extender
This device connects to the airtalk link of an Enigma, Odyssey or Voyager EFIS system. This allows you to extend the EFIS with comprehensive digital and anlog signal monitoring as well as driving automation and alarm annunciator panels. The I/O Extender is also used to allow remote control of certain EFIS functions via joystick mounted push buttons etc.

USB COM Extender

This device extends the number of RS232 serial ports for Enigma, Voyager and Odyssey EFIS systems to a total of six ports (two are available on the EFIS).
In addition this unit includes the servo interface section of the integral autopilot and it provides as part of this four PWM outputs that can be used with servos that accept this type of signal.

The COM Extender is simply connected to one of the USB host ports of the EFIS system using a standard USB printer cable (included or use your own), no further setup is required other than assigning functions to the varous ports from within your EFIS setup.

Optional accessory capstan kit

This precision machined capstan kit allows conversion of a standard MGL Servo to a capstan servo. 

The MGL Avionics Autopilot servo

The MGL Servo is a stepper motor based system providing a torque of up to 4.8Nm (with shaft rotating).
The servo is not restricted to any particular range of the output arm movement and can be used at any angle in this regard.
This servo is able to measure the external force acting on the output shaft for use with trim indiction or automatic trim systems.
External control is either via a multi-drop RS232 link or a CAN interface at 250KBaud.
Multiple, threaded mounting points are available on the face and sides of the servo for ease of installation.

The MGL Servo can be used with the Enigma, Voyager and Odyssey EFIS systems. This servo will also be supported by the XTreme EFIS autopilot function.

For the XTreme, Voyager and Odyssey EFIS systems, this servo is controlled through the built in CAN interface and no COM Extender module is required.

For the Enigma, this servo is controlled through a RS232 serial port, either the built in RS232 port 1 or Port 4 on the COM extender. Only a single port is required to control multiple servos.

Please note: Odyssey, Voyager and Enigma also support Trio Avionics Gold standard servos via a COM Extender module. The Trio servo is a DC motor based servo using an electric clutch and effectively has zero residual torque when not engaged. This may be of advantage in certain applications.

MGL Servo optional accessories:

We have a kit available containing required parts to construct a servo linkage using reft and right hand thread rod end bearings (shown on picture left).

Converting the servo to a capstan servo is simple using the optional capstan conversion kit that includes all required parts.

Please note: the capstan kit uses flexible steel cable around a drum. This cable should have a diameter of approximately 1.5mm. This cable is not included in the kit and must be supplied by the installer depending on required length. This cable is typically fixed to the actual, larger diameter control cable using clamping blocks. These clamping blocks are supplied. Minor alteratrion of these block may be required to suit actual control cable diameter.

Magnetic field DC current measurement sensor

This sensor can be used to measure DC currents in aircraft power systems in a wide range from less than 4A to as high as 120A depending on installation and configuration. The sensor connects to an EFIS system via spare RDAC inputs. Inputs CHT1,CHT2,OIl pressure or Oil temerature can be used and these can also be used on a second RDAC unit (consider a low cost RDAC VD as second RDAC if required). G1 and G2 EFIS systems can support up to 4 of these sensors while Enigma can support 2. These sensors can measure currents bi-directional, for example battery charge/discharge. The major advantage of these sensors is that they can be fitted to existing conductors very easily without a need to break the conductor or require the use current shunts.
