Master/Satellite (T/Net) Option
System Overview
Master/Satellite (T/Net) Option
The master/satellite option (also called the T/Net option), allows you to network up to 8
TopKAT units together to control a maximum of 16 hoses (electronic and mechanical
combination). If all your pumps are 9800 electronic pumps or you have mechanical PCUs, up
to 8 hoses may be controlled. One TopKAT functions as the master unit, the remaining units
function as satellites. A single database resides at the master consisting of system data, vehicle
file data, manual entry file data, transaction, pump, and tank data.
The master TopKAT provides the satellite with the vehicle and (if configured) the manual
entry records required to authorize a transaction. If your configuration is all 9800 electronics
or uses mechanical PCUs, the TopKAT master controls all pumps. If you are using a
combination of 9800 electronic and mechanical pumps, the master controls the electronic
pump (one PCU, single or twin pump) and the satellite controls its local mechanical pump(s)
and returns completed transaction data to the master upon completion of a sale. The master
TopKAT then updates its database with transaction information.
The TopKAT with the master/satellite option is set up and configured slightly differently from
a standalone TopKAT. The differences are as follows:
)
This new prompt is present in all TopKAT units. When your TopKAT is a standalone
unit, this prompt is set to standalone. When using the master/satellite option, the master
unit is designated as Master. This prompt must be set to Satellite at each satellite unit.
• Poll Address (refer to
Functions the same as for standalone TopKAT units; however the master must be set as 01
and the satellites must be set as 01 through 07.
• Password (refer to
)
Can be loaded at master and at satellites.
• Config Trans File (refer to
“Transaction File Setup - Keypad”
All functions available at master unit; only Clear Trans in Progress, available at satellite
unit.
• Satellites controlling mechanical pumps are recognized as individual Pump Control Units
(PCUs) and are configured at the TopKAT master, using the PCU SETUP keypad
sequence (refer to
“Tank, Pump, and PCU File Setup - Keypad”
on
) and/or the
CONFIGURE SYSTEM and CONFIGURE PCUS terminal commands (refer to
).
• Diagnostics are available at the keypad of both the master and satellite units; however, the
system must be stopped or the satellite must be offline. Enhanced diagnostics from the
terminal are effective only for the master unit.
• Certain options, such as PCMCIA backup and restore and report printing are available
only at the master unit.
