Apply power to the digitizer and after the data appears on the PC screen type the
following:
Type
<enter>
The Digitizer will return “?> current altitude”
Type ADJ
<enter>
Access the digitizer adjustment program.
The Digitizer will return A=
Type
P <enter> To identify the current serial port settings.
(a)
The first digit represents the serial altitude data resolution.
0 = Use D-Sub connector protocol hardware jumpers.
1 = 100 foot resolution on TxD1 and TxD2.
2 = 10 foot resolution on TxD1 and TxD2.
(b)
The second digit represents the protocol selection for TxD1.
0 = Use D-Sub connector protocol hardware jumpers.
1 = UPS Aviation Technologies. 1200 bps.
2 = Trimble/Garmin. 9600bps.
3 = Northstar. 2400bps.
4 = Magellan. 1200bps.
5 = ARNAV. 9600bps.
(c)
The third digit represents the protocol selection for TxD2.
0 = Use D-Sub connector protocol hardware jumpers.
1 = UPS Aviation Technologies. 1200 bps.
2 = Trimble/Garmin. 9600bps.
3 = Northstar. 2400bps.
4 = Magellan. 1200bps.
5 = ARNAV 9600bps.
Example:
Type
P212<enter>
Defined as
10 foot
resolution on TxD1 and TxD2.
UPS Aviation Technologies
protocol transmitted
on TxD1.
Trimble/Garmin
protocol transmitted on
TxD2.
Type
Q
twice to exit the adjustment mode.
The Interface Adapter responds with a three-digit number as follows:
a b c
