Flash Drive Only USB Port:
Standard USB drives
that have been programmed with ThermoServ can
be used in the Flash Drive Only USB Port. Use of
a USB drive eliminates the need for an on-site
computer and does not require cables.
The Flash Drive Only USB port can be used to:
•
Upload and download OptiSet Plus files.
•
Download the CargoWatch and ServiceWatch
Data Loggers.
•
Flashload the Base Controller and HMI
Control Panel.
PC Only USB Port:
The PC Only USB Port is the
J11 connector located on the base controller inside
the control box (see Figure 153 on page 84). It is
used to connect the controller to a PC with a
standard USB to USB mini cable P/N 204-2000.
The PC Only USB port can be used to:
•
Upload trailer ID and Unit Serial Number
(Must be done on new units and if new
controller is installed.)
•
Upload and download OptiSet Plus files.
•
Data Logger setup.
•
Download the CargoWatch and ServiceWatch
Data Loggers.
•
Flashload the Base Controller and HMI
Control Panel.
Refer to TK 55533 the SR-4 Microprocessor
Control System Diagnostic Manual and for
information about using the USB ports.
ServiceWatch™:
ServiceWatch is standard
equipment. It records operating events, alarm
codes and compartment temperatures as they
occur and at preset intervals. This information is
typically used to analyze unit performance. Use a
USB port to downloaded the ServiceWatch data.
IMPORTANT: A ServiceWatch download can be
helpful when diagnosing a problem in a unit
with an SR-4 Controller. Therefore, it is
recommended that a ServiceWatch download be
preformed to help diagnose a problem. A
ServiceWatch download must be preformed
before contacting the Thermo King Service
Department for assistance in diagnosing a
problem. Refer to the SR-4 Microprocessor
Control System Diagnostic Manual TK 55533
for information about downloading the
ServiceWatch Data Logger and viewing the data.
CargoWatch™:
CargoWatch data logging requires
the installation of optional sensors. Up to six
temperature sensor/probes and four door switches
can be installed. CargoWatch also logs the
setpoint. Use a USB port to downloaded the
CargoWatch data. If optional temperature sensors
are installed, their readings are displayed as
Datalogger Sensor (1-6) Temperature in the
sensor readings. See “Using The Sensors Key” on
page 49.
A printer can also be used to print a report of the
optional sensor readings. See “Printing
CargoWatch Data Logger Reports” on page 61.
CargoLink™
CargoLink™ is a wireless sensor system. The
main components are the coordinator module,
interconnect harness, antenna, and wireless
sensors. The coordinator module receives
information from the wireless sensors through the
antenna, and communicates with the controller
through the interconnect harness. Currently, only
wireless door switches are available. Other
wireless sensors will be available in the future.
