XX = Current GPA or PPA Units digit
2E = Decimal Point
XX = Current GPA or PPA Tenths digit
00 = NULL
Checksum = undetermined
7. Read Channel 1 Type (24 06 02 F1 03)
24 = Start of message
06 = Read Message
02 = Two Character Message
F1 = Channel 1
03 = Channel Type
Checksum = 35
The 8605 will transmit a Channel Type Reply
message in response to a Read Channel Type
message. It will reflect that the channel is either
a liquid type or an NH3 type depending what is
selected.
Transmitted Channel Type Reply Message
24 = Start of Message
F1 = Channel 1 Data
02 = Data Field Size
03 = Channel Type Info
Depending on which mode the 8160 is in the re-
maining characters of the message will be:
Spray Mode
02 = Channel 1 liquid Type
39 = Checksum for Liquid
OR
NH3 Mode
03 = Channel 1 NH3 type
38 = Checksum for NH3
8. Read System Statistics - Proprietary (24 06
02 F0 FF)
The breakdown is as follows:
24 = Start of message
06 = Read Message
02 = Two Character Message
F0 = System
FF = System Statistics
3A = Checksum
When received, the parser will transmit the fol-
lowing snap shot of actual rate, speed in MPH,
and active boom width in inches.

00 = NULL
XX = Checksum
The “current active boom width” should repre-
sent the total width of all boom sections that
are turned on. If the Run/Hold switch is in the
hold position, the boom width returned should
be zero.
“GENERIC” PROTOCOL
The “Generic Protocol” is only available in soft-
ware version 3.0 or higher. If you have earlier
versions the 8605 will need to have the software
updated.
If the “GENERIC” protocol is selected the 8605
will prompt you to turn Logging “ON” or “OFF”.
Selecting “LOGGING = ON” will instruct the
8605 to start sending data to the serial port once
per second. “LOGGING = OFF” turns this fea-
ture off. For most applications this is turned on.
The “GENERIC” protocol will use the current
field number as the field identification that is sent
to the mapping system.
