7.2 Programming
When the i50 Programmer starts for the first time, it will ask which PC COM port should be used to
connect to the i50. This can be changed at any time using the Connection/Select Port menu. Once
the port is selected, the programmer will attempt to open the connection and send programming
commands to the i50. If the port is open at the time the programmer application is closed, it will
automatically be opened the next time the programmer starts. The Open Port and Close Port buttons
can also be used to open and close the port manually.
Connect the i50 to the PC COM port, and reboot the i50 to enter programming mode. A reboot can
be forced by removing power briefly, or by using the Reboot button on the programmer toolbar. Note:
the reboot button only works when the PC is connected to the device’s RJ-45 Program connector. If
successful, the programmer will show a “Got settings OK” message, along with the detected firmware
version and any optional features.
Optional features can be included in custom firmware, depending on customer requirements and
available firmware space. The current options include:
Accel: 3D accelerometer support
AES-256: Encryption available on the i50C only
PDT: Support for PDT-100 satellite terminal
GS: Globalstar 1620 support
Dial-up: Allows a third-party to connect to an i50 serial port using PPP
RF: RF modem support
OBD-II: External OBD-II engine monitoring
Driver: Driver ID features (when using Garmin terminals)
Wi-Fi: Internal Wi-Fi module
No Waypts: Waypoints turned off
Grace: Support for Grace pagers
Kenwood: Enables interface to NXDN/Fleetsync radio systems
Garmin: External Garmin terminal for messaging and route planning
Signs: Transparent data port modified to talk to portable road signs
NTCIP: Transparent data port modified for NTCIP signs
Amsig/NTCIP: Transparent data port can send to portable or NTCIP signs.
The programmer automatically reads the asset’s settings, which are shown under the “Current Asset
Value” column. If no local data exists, the programmer automatically creates a local copy that can be
modified by a user, shown under the “New Value” column. Figure 4 shows the settings window where
two values have been modified by a user. Any settings that do not match the asset values are shown
in red, and a red bar is displayed to warn of the mismatch. This provides a quick method of tracking
changes before they have been sent to the asset. At any time the current asset values can be copied
into the local values using the Copy Asset Values button, erasing any changes the user has made.
