RF TAG SUBSYSTEM COMPONENTS
The RF TAG SUBSYSTEM includes the following components (see illustration below):
Note
For a more detailed illustration of the RF TAG SUBSYSTEMS, see sheet 2 of the 8150 Functional
Diagrams. (Functional Diagrams are on the Kodak Health Imaging Digital Output Service Collection
CD set.)
RF TAG INTERFACE BOARD -- This BOARD contains a micro which communicates (at 512 K baud)
•
with the MCS on the MicroComm serial channel. The micro builds commands which can be
recognized by the RF READER BOARD, and sends these through a circuit which converts the VCC
(or /TTL) levels to + 8 volt RS232 levels. The commands are sent at 67.4 K baud to the READER
BOARD. Data received from the READER BOARD goes through a reverse conversion process before
being input to the micro.
The RF TAG INTERFACE BOARD contains a pair of DIP SWITCHES. The left SWITCH, which is
normally open (down), can be closed to test the ROLLBACK OPEN SENSOR. The right SWITCH,
which is normally down in the 8150 IMAGER, is used in 8200 IMAGERS to identify the position of the
ROLLBACK MODULE as upper or lower.
RF READER BOARD -- This BOARD receives commands from the RF TAG INTERFACE BOARD. It
•
processes data for transmission to the RF ANTENNA, receives RF data from the ANTENNA, and
responds to the RF TAG INTERFACE BOARD.
RF ANTENNA BOARD -- The ANTENNA transmits to and receives RF energy from the RF TAG.
•
ROLLBACK OPEN SENSOR S13 -- This SENSOR conducts (high output) whenever it is not blocked
•
by the VANE on the bottom of the ROLLBACK CARRIAGE. When the CARTRIDGE LID is fully
opened (rolled back), the VANE blocks the SENSOR and it turns off.
