5.2 Detailed Interface Definition
Figure 32 and Figure 33 show the default external system interfaces supported by the MARK III CMU. The default external system interfaces, including the bus speeds, are modifiable using the APM.
The rear connector is a standard unit connector as defined in ARINC 758. The function and type of circuitry connected to the pin is listed in the table. All pins named ‘Spare’ are Honeywell reserved for future growth.
The front panel PDL circular connector is a standard 53-pin connector that is defined in ARINC 615. The function and type of circuitry connected to the pin is listed in the table. All function input and outputs are referenced to the CMU (DLT Input is input into the CMU and output from the terminal).
