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 be printed from a PC in short or long form reports. From the DataReader, it can be
transferred to a personal computer (PC) for l ong-term storage on a floppy or hard disk.
The DataView software for a portable computer is supplied on 3.5 inch floppy disks for DOS (refer to Table 1-1). This
software allows data extraction, screen view of the data, hard copy report generation, USDA cold treatment probe
calibration and file management.
The DataCORDER records and stores data. While this manual primarily addresses the interrogation of the
Micro-Link 2 and the Micro-Link 2i DataCORDER (see Figure 1-1 and Figure 1-2), interrogation can also be done on
units with the Micro-Link 1 DataCORDER (see Figure 1-3). Additional information on the DataCORDER may be
found in the unit Operation and Service manuals. Please refer to the separately bound manuals listed in Table 1-2.

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 battery pack)

1.2.2 Micro-Link 2i Controller/DataCORDER
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.

1.2.3 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.

1.2.4 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 these inputs, an additional eight sensors connected to the refrigeration or controlled
atmosphere controllers can be recorded.
1. This list of sensors includes:
2. Humidity Sensor
3. Controlled Atmosphere Gas Sensors
4. Temperature Controller Probes (including: supply, return, and defrost temperatures)
5. Controller Pressure Sensors
6. Current Sensors
7. Line Voltage Sensor
8. Frequency
NOTE
The supply and return sensors (SRS and RRS) used by the DataCORDER are not the same supply and return
sensors (STS and RTS) used by the Controller.
b. Log Interval
Micro-Link DataCORDER’s log data on 60 minute intervals from time of trip start. Micro-Link 2/2i DataCORDER
sensors can be recorded at intervalsof 15, 30, 60 (default), or 120 minutes. Data is logged on the exact interval, using a
precise real time clock (RTC). All clocks are set to Greenwich Mean Time at the factory and all recording i s done on
the exact interval (at 12:00 for example, rather than 12:03).
NOTE
Unless specified by your customer to set the DataCORDER clocks for another time zone, the clocks should
NOT be adjusted.
c. Sensor Recording Format
Sensors can be recorded in a wide variety of formats. A one byte temperature format can be used for compact data
storage. A two byte format can be used for high resolution over the entire temperature range.
1. One byte format (default): 0.25C(.45F) steps in chilled mode; 0.5C(.9F) steps in frozen mode
2. Two byte format: 0 .010C steps for entire range
d. Sampling Type
1. Averaged (default): shows average of data from every minute over the logging interval.
2. Snapshot: shows snapshot of data at the log interval.
3. USDA: shows snapshot of data at a 60 minute log interval.
1-562-02575-07
1.3 DataCORDER INTERFACE
The DataCORDER is capable of performing the following functions initiated by the DataView Program
1.3.1 Data Extraction
a. Daily Header Data
Recorded days are presented in the following format:
1. Day 1 date (month, day, year), sensor data, events, ...
2. Day 2 date (month, day, year), sensor data, events, ...
b. Sensor Data
Sensor data will be read based on either standard or generic configuration. Pl ease refer to separately bound manuals
covering the Refrigeration Unit for further explanation of standard and generic configurations, see Table 1-2.
1.3.2 Events
Events will be transmitted to the DataCORDER as specified in Table 1-3, Table 1-4 and Table 1-5. The
DataCORDER compacts the events, disposing of repetitive events to save memory space. All events have a time and
date stamp.

1.4 USDA RECORDING
A special type of recording is provided for USDA cold treatment purposes. Cold treatment recording requires that
three remote temperature probes are placed in the cargo at various locations. Provision is made to connect these probes
to the DataCORDER via receptacles located at the rear left-hand side of the unit. Four (five, on some units) receptacles
are provided. Four (three-pin) receptacles are for the probes and one (five pin) receptacle is provided for the
Interrogator. All receptacles are sized to accept a Deutsch HD16-5-16S size plug with a tricam coupling locking
device. The DataCORDER inputs are designed to accept a two wire thermistor probe.
A label on the back panel of the unit shows which receptacle is used for each probe. The USDA #1, #2 and #3 probes
(and possibly the optional Cargo probe) are installed in these receptacles.
The DataCORDER records up to six probe temperatures(supply,return, USDA #1, #2, #3 and an optional cargo probe
#4), at the logging interval.
The standard DataCORDER reportdisplays the supply and return air temperatures. The cold treatment report displays
USDA #1, #2, #3 and return air temperatures. Cold treatment recording is backed up by a battery so recording can
continue if AC power is lost.
NOTE
There may be an additional (3-pin) receptacle for a cargo probe on some units. This should NOT be used for
USDA probes.
1.5 RELATIVE HUMIDITY
When the Relative Humidity Set Point mode is activated or de-activated (i.e., Controller function code Cd33 on
Micro-Link 2/2i), this status is stored in the DataCORDER memory and reported as an event.

SECTION 2
SYSTEM SETUP
2.1 HARDWARE PLATFORMS SUPPORTED
The DataView S oftware will run on a variety of DOS based m achines. We recommend the use of a desktop or laptop
machine with at least 3MB free disk space and a VGA monitor for displaying graphics, for most printing and report
generation functions. Other, less capable computers may be used for the actual data extraction.
2.2 INTERROGATION CABLES
Cable requirements may differ between interrogation devices. For cable connections see Figure 2-1.

2.3 PRINTER SUPPORT
Formatted reports can be generated on the following printers:
1. EPSON 85 dot matrix or compatible (most dot matrix printers will support this format)
2. HP LaserJet or equivalent (Many laser printers will support this format).
For printers that are not compatible with the above printers, select the FILE printer port option in printer setup. This
will send the report t o an ASCII print file.
2.3.1 PERSONAL COMPUTER PRINTING CABLE CONNECTIONS
After the DataCORDER has been interrogated, the data may be printed from a PC to a parallel or serial printer. Printer
cables will differ depending on the type of printer.
a. Parallel Printer
If you are connecting to a parallel printer, a standard Centronics type printer cable may be used (see Figure 2-2). The
printer cable connects to the printer port on a PC.
