SECTION 1
DESCRIPTION
1.1 HARDWARE AND SOFTWARE
This manual contains information on the Carrier Transicold DataView Program and its interface with the
DataCORDER. The DataView program is used to retrieve data stored in the DataCORDER.
Data retrieval can be accomplished with one of the following devices:
1. Stand-alone DOS based portable personal computer (PC) with appropriate cable and software
2. Carrier DataReader hand held interrogator (refer to Section 4)
The retrieved data can then...

1-2 62-02575-07 1.2.1 Micro-Link 2 Controller/DataCORDER
The Carrier Transicold Micro-Link 2 Controller (see Figure 1-1) is a custom-designed, microprocessor-based control
system which is fitted with a separate DataCORDER module. The DataCORDER consists of:
1. Microprocessor
2. Program memory
3. Data memory
4. Real time clock (RTC)
5. Six thermistor inputs (2 Air Temperature and 4 Cargo Temperature)
6. Two voltage inputs
7. Four status LED’s
8. Two communication ports (serial)
9. Power supply (optional...

The Micro-Link 2i Controller is an integrated Controller and DataCORDER assembly, but is otherwise identical to
the Micro-Link 2 Controller. Scroll compressor units are also fitted with a controller Expansion Module located next
to the Controller/DataCORDER.

1-4 62-02575-07 1.2.3 Micro-Link 1 Controller/DataCORDER
The Carrier Transicold Micro-Link 1 Controller (see Figure 1-3) predates the Micro-Link 2 Controller. Micro-Link 1
units with the DataCORDER option are equipped with a DataCORDER that is an integral part of the Controller.
Interrogation of Micro-Link 1 and Micro-Link 2 Controllers will have some differences.

1-5 62-02575-07 1.2.4 DataCORDER Capabilities (Micro-Link 2 and Micro-Link 2i only)
The Carrier DataCORDER is a flexible recording device with the following capabilities:
a. Sensors
Up to six thermistor temperature probes can be connected directly to the DataCORDER.
These probes are referred to as:
1. Supply
2. Return
3. USDA 1
4. USDA 2
5. USDA 3
6. Auxiliary Cargo Probe
On separate DataCORDER modules (Micro-Link 2 only) there are also two 0-5vdc inputs available for future
expansion. In addition to...
