Unpacking Procedure
To remove the SCS from its shipping container:
1. Open the shipping carton and remove the unit from the carton.
2. Carefully remove the unit from the packing material. Be sure to remove all parts
and literature from the carton.
3. Remove the remaining packing materials from the SCS and store with the

To prepare the SCS for operation:
1. Place the SCS in its permanent location.
WARNING!Do not place the SCS in a location where it could be exposed to
direct sunlight during operation.
♦ Position the instrument to meet the minimum clearance of 50 mm (2 in) on all
sides and 30.5 cm (12 in) above the instrument to provide adequate space for
placing cassettes onto the unit.
2. Properly connect all cables, plugs, etc. Refer to figure 2-2 for the cabling
connections.
3. Switch power ON. (The SCS power switch is located on the back of the unit.)
4. The bioMérieux logo or the configuration screen will be displayed within a
minute. If the screen is not displayed, try adjusting the Screen Contrast (A) so the
screen display is visible. If there still is no display, switch the power OFF and
restart at step 2.
5. Once the configuration screen is displayed, set the desired configuration settings.
For details on these settings refer to the VITEK 2 User’s Manual.
6. If problems are encountered in setting up the unit, refer to chapter six of this
manual for troubleshooting information.

Unit Description
The VITEK 2 Smart Carrier Station (SCS) is a dedicated, PC-type computer. Laboratory
technicians enter test card and specimen information into the “button” memory of the
cassette for transfer to the VITEK 2 instrument. The unit consists of:

Cassette
The cassette holds up to 15 test cards with the associated specimen test tubes. A cassette
is shown in figure 3-2. The button memory device is located in the bottom of the cassette
as shown in figure 3-3. Although the cassette has three sockets for memory buttons, only
one is needed. The button memory device is programmed by the SCS via two contacts on
the Base Unit which connect electrically to the memory when the cassette is placed on
the Base Unit.

The cassette is placed in the VITEK 2 instrument for card processing, incubation, and
analysis. If the VITEK 2 was previously set-up in Smart Carrier Mode and the cassette
memory device instrument was programmed at the SCS, the VITEK 2 will read the
memory. This non-volatile memory contains the patient, test, and carrier-specific
information for the system. After the data has been read by VITEK 2, it tags it as “read”
in preparation for the next use of the cassette.
NOTE: The data remains on the cassette memory device until it is erased by
the SCS. If necessary, that data can be read by the VITEK 2 instrument
for diagnostics purposes after it has been tagged as “read.”
Base Unit
The Base Unit contains the computer electronics such as the Power Supply, CPU,
memory, disk storage, and video controller. It also contains connection points for the
power cord, serial communication link, the Bar Code Scanner, and the keyboard.
Figure 3-4 shows a photograph of the back of the Base Unit. Figure 3-5 is a drawing
showing the location of each of the connection points.

Bar Code Scanner
The Bar Code Scanner allows the lab technician to enter information into the SCS by
scanning the bar codes printed on the test cards or those on the SCS Job Aid card. If the
laboratory uses bar codes for accession numbering specimens, this information can also
be entered via the scanner. Scanned data automatically appears in the appropriate field on
the Display Screen after each successful scan. The scanner can be used with an optional
holder (passing the bar codes by the scanner), or it can be held by the technician (and
aimed at the bar codes).
The Bar Code Scanner (Welch Allyn Imageteam 3800) can read the following industrial
symbology: CODABAR, CODE39, INTERLEAVED 2 of 5, CODE 2 of 5, MATRIX 2
of 5, CODE 11, CODE 93, CODE 128, IATA CODE 2 of 5, Telepen, UPC, EAN/JAN,
