4.10 Serial Port Software Configuration Using the ECP-100
This procedure will allow the technician to assign separate serial data output protocols to the altitude
digitizer output port groups. Connect the ECP-100 to the altitude digitizer as shown in Figure 3.
Step 1: With the ECP-100 and altitude encoder power off, Slide the CAL. Program switch to its
rightmost PROGRAM position and connect the ECP-100 to the altitude encoder, as shown in Figure
3.
Step 2: With the ECP-100 power switch in the OFF position, apply power to the altitude encoder,
then slide the ECP-100 power switch to the on position. The ECP-100 will beep twice then display
the current pressure altitude transmitted from the altitude digitizer.
Step 3: Push the READ SET-UP DATA pushbutton once. The ECP-100 will display the current serial
port protocol settings for 15 seconds, and then return to the altitude programmer display page. The
factory setting is pictured below.
100 Foot Resolution
TxD1= UPS 1200bps
TxD2= UPS 1200bps
TxD1 on the ECP-100 will set the serial data protocol for TxD1, TxD2 and TxD3. While TxD2 on the
ECP-100 will set the Serial data protocol for TxD4 and TxD5.
Step 4: Slide the RESOLUTION selector to the desired altitude data resolution 10' or 100'.
Step 5: Rotate the TxD1 and TxD2 selector knobs to the desired output protocol. For the purpose of
this example we will set TxD1 to transmit the UPS protocol and TxD2 to transmit the Trimble/Garmin
protocol.
Step 6: Press the INITIATE PROGRAM pushbutton once. The display will beep then flash
PROGRAMMING and display the protocols to be programmed. Wait until the ECP-100 emits a long
beep and displays OPERATION COMPLETED then returns to the ALTITUDE PROGRAMMER
display.

Step 7: Confirm the port programming by pressing the READ SET-UP DATA pushbutton. It should
display the settings applied in the previous steps. In the case of our example the display would
appear as below.
