Caution:
Do not disconnect the Static hose from the Static port unless the aircraft Static
system is at “Ground” level.

Pitot ports :
The Pitot output is provided on two ports that are internally connected. Both ports have #4
AN fittings. At least one of these ports must be connected through a hose to the Pitot port on
the aircraft. The hose must be connected
after
performing the Self Test on the 6300-M3. The
hose, once connected, must not be disconnected while the aircraft Pitot system is not at
“Ground” level. An unused port must remain closed.
Caution:
Do not connect the Pitot hose to the Pitot port before performing the Self
Test.
Caution:
Do not disconnect the Pitot hose from the Pitot port unless the aircraft Pitot
system is at “Ground” level.

RS232 interface connector:
This connector is accessed by opening the “Interface Connectors” access panel. The
connector is a standard DB-9 female connector used for a serial RS232 interface. It can be
connected directly to the “COM” port of a standard PC to allow communication. This port is
normally used for downloading “profiles” from a computer. Other remote communication
with the 6300-M3 is also possible through this interface. Figure 2.2 shows the RS232 connector
(6) with the panel removed. For more details on downloading profiles, please refer to Section
4. For more details on communication with the 6300-M3, please refer to Section 8.

Encoder interface connector:
This connector is located under the “Interface Connectors” panel. This DB-15 connector is
used to connect to an altitude encoder. The pin-out for this connector is provided in
Appendix C. The connetor provides 12 volt power for the encoder and connects to the 10
output bits of the encoder. Further details on how to access the encoder’s 10-bit code and
view it on the 6300-M3 display, are provided in Section 3.5.9.

Static Vent :
In the event that the 6300-M3 is in-operable due to a malfunction or due to loss of power, it is
possible to vent the Static system manually. This is done using the metering valve labeled
“SV”, located under the panel labeled “Interface Connectors”. This valve is a positive shut-off
valve. Opening this valve slowly will vent the Static output of the 6300-M3 to ambient
pressure. While venting, care must be taken to ensure that the maximum climb rate of the
