NN. Data Loader unit Targa (RS-422)
This section describes the RS-422 data words and the transmission protocol of the interface Targa data loader and CMA-9000 FMS.
When the Targa DLU is configured, the data loader unit sends/receives data to/from the FMS. The communication between the DLU and FMS takes place over the RS422 serial link at 38.4 kbps using the Packet Data Protocol PDP/3-DOS.
In order to load files from the Targa DLU to the FMS, the following file extension convention shall be used (otherwise, file transfer is not performed):

Page May 10, 200785OO. Helicopter Communication System (HCS) Software Protocol (RS-422) Future Growth
This section describes the RS-422 data words and the transmission protocol of the HCS interface and CMA-9000 FMS.
(1) HCS Software Protocol
(a) Transmission of Data Frames
The information interchange is based on simple data frames that start with the ASCII character STX and end with an ETX. The maximum frame length including ETX and STX is 512 characters. Data can be sent without delay between the characters. The receiving system has to read in the complete frame as fast as the data are sent. There is no flow control mechanism to stop the sending station.
(b) Polling
The FMS polls the Helicopter Communication System periodically. That means a Command or Request Frame is sent by the FMS and the HCS answers in an Answer Frame.
Serial Message Frame Types between the HCS and the FMS:
FRAME TYPE DESCRIPTION
Command/Request Frame The FMS sends a Command or Request Frame to the HCS. Answer Frame The HCS answers in an Answer Frame
(c) Command / Request Frame
If the FMS sends a Command Frame to the HCS, the HCS will respond with an Answer Frame that consists of STX, Status Code (0,1,A,B,@), Attention Code, Checksum and ETX. The FMS can decide whether the command has been accepted depending on the Status Code.
If the FMS sends a Request Frame, the HCS responds with an Answer Frame that may have the result of a previous command of this type in the Answer Area. If not, the Status Code informs the FMS that the Command is not yet processed.
