Installation and Troubleshooting Tips
Installing and Troubleshooting a New
Operating System Version
Installation
New versions of the Horizon operating system will
periodically be released in the form of a set of three
microchips, known as firmware. The chips are located
on the circuit board of each control module (master
and slave), and are designated U6, U7 and U11. See
page 71 for instructions on installing the new chips
(software).
Powering Up the System
After changing the chips in each control module, the
control module can be powered up. The attached
keypad should boot up normally, displaying the HOME
screen after 10--15 seconds. If the HOME screen does
not appear, take a close look at the pins on each chip
you replaced. If a pin is bent or not making contact with
the connector, it can prevent the control module from
operating properly.
Verifying the Version
The software version of these chips is marked on
them, but it can also be determined by going into
SETUP " DIAGNOSTICS " ABOUT. See page
26. All control modules in the system need to have the
same version of the firmware loaded.
The ABOUT screen also gives information about the
condition of the information contained in the memory
chips, also known as "Checksum".
D The line labeled FIRMWARE CKSUM (checksum)
will display four characters, which should be the
same on all control modules. If it is not the same,
the program has been damaged.
D After all the SETUP information has been loaded,
but before any jobs have been entered, the line
labeled DATA CKSUM on each control module
should match. If they do not match, the transmis-
sion of the tables from the Master Control Module to
the Slave Control Module was not completed suc-
cessful and should be done again.
a. Check the condition of the CAN cable and
ensure that the CAN is enabled on all the
control module. See page 64, Problem: Net-
work communication is not operating pro-
perly.
b. Try SETUP " UPDATE TABLES " ALL
TABLES to send the tables again (page 25), or
you may have to CLEAR SETUP " ALL
MEMORY (page 23) to erase the memory of
all control modules before sending the tables
again.
NOTE: After jobs have been entered, the line
labeled DATA CKSUM will vary depending upon
the exact system configuration and what jobs are
currently active on the system at the time.
Rebooting
After verifying that the checksums match on all control
modules, and the system configuration has been
successfully downloaded to each control module, turn
the power off, wait 10 seconds, and turn the power
back on to all boxes.
Run a test job to each dispense point to verify proper
operation. See the other sections for troubleshooting
any problems that may have occurred since the firm-
ware was changed.
Reboot After Setup or System Changes
The entire system (all control modules) needs to be
rebooted after entering the system setup data and after
making any system changes, such as adding new
operators/passwords, updating inventory information,
etc.
Printing Configuration Information
You can print out the system configuration information
using SETUP " PRINT SETUP " ALL MEMORY
or select individual tables to print. See page 24.
NOTE:
The numbering scheme of the printout will not match
the numbering scheme of your data entry. Many of the
parameters that were entered, starting with 1, 2, 3,
etc., will begin with 0, 1, 2, 3, etc., in the printout. This
is due to the internal numbering scheme of the operat-
ing software.
To match the printout with the tables used for data
entry, subtract 1 from each entry.
For example: solenoid ports are numbered 1- -6 exter-
nally, 0- -5 internally; meters are 7- -12 externally, 6- -11
internally.
