Programming and Operation
The micro-controller in the ADFM Analog Output Module is most easily
programmed using the Windows95 based software available from Parallax.
Programming the micro-controller consists of the following steps:
a. Starting the software, opening the program file for the site
b. Connecting your computer to the DB-9 connector on the module la-
beled P5-BS2
c. Rev B only: Switch SW2-1 must be in the "ON" position.
d. Loading and running the BASIC program in the micro-controller us-
ing the software menu functions
e. Rev B only: Switch SW2-1 may be set to the "OFF" position to
avoid inadvertently resetting the micro-controller.

ADFM Analog Output Module Configuration
Certain functions of the ADFM Analog Output Module are enabled or dis-
abled using a series of DIP switches on the circuit board. This switch bank
is labeled SW2. Individual switch functions are as follows:
Table E-2:
Switch
Function
SW2-1
Enables micro-controller programming (Rev B
only)
SW2-2
Force default mode in DGH modules (Rev B
only)
SW2-3
Isolate micro-controller from ADFM data
stream
SW2-4
Isolate DGH module (flow) from micro-
controller
SW2-5
Isolate DGH module (depth) from micro-
controller
SW2-6
Isolate DGH module (velocity) from micro-
controller
For normal operation, switches 1&2 should be in the "OFF" position and
switches 3-6 should be in the "ON" position. If necessary, the module's
micro-controller can be reset using the SW1 momentary pushbutton switch,
located just above the P5-BS2 connector. When reset, the micro-controller
will go through its initialization procedure and resume normal operation.
