    These conditions are not negotiable and will not be waived. Should the entity not accept these conditions MGL Avionics does not grant the right to use any of this information in any way. Usage of this information constitutes acceptance of a legally binding contract in the spirit of information placed in the public domain for the common good.

  • Page 4: Frequencies

    Command messages containing frequency request that are not within the permitted airband or illegal channel frequencies are ignored and not acknowledged. The V16 provides two RS232 ports and one CAN bus. Only RS232 port 1 supports this protocol. RS232 port 2 is reserved for special functions.

    This form of checksum is also known as longitudinal checksum or 8 bit parity. Note: This protocol is based on the protocol used by the MGL Avionics V6 and V10 transceivers. Note that the commands and status messages are not all identical.
  • Page 6 Note: Frequency must be a valid frequency. Invalid frequencies will be ignored and no acknowledge will be sent for the message. Sends acknowledge when message received OK Increase RX and Intercom volume (3dB), If they are different they will be set to the same value as the intercom volume.
  • Page 7 6: Technical setup de-activate (power on state) 7: Technical setup activate If the V16 is placed in setup menu mode it will automatically cancel this mode if no activity within 60 seconds related to the Menu. If the menu is active the Setup menu message will be sent every 200mS interspaced with the normal status message.

    The ID takes the value 0x44n for COM1 and 45n for COM2 where “n” can be a value from 0 to 15 depending on message type. Setting a V16 to COM1 or COM2 is done via dedicated CAN command described in this section.
