15. Patient Data Card
An electrical loop is closed when a PDC is inserted into the PDC
Reader. The reader is connected to PIB-J1 through a 10-pin
connector.
15.2.3 Peripheral Interface Board (PIB)
The PIB consists of Power, Card Inserted Sense, Data and Clock
signals for the PDC (refer to Section 5, Electronic Theory). The
PIB provides a direct connection between the PDC Reader and the
Single Board Computer (SBC). The signals from the PDC Reader
enter the PIB through J1 and exit to the SBC through PIB-J5. The
PIB also provides +5 VDC and digital ground for the PDC Reader.
The +5 VDC is protected by Fuse F2.
There is a red LED (DS1) in the upper left side of the board. This
LED should be ON to indicate +5 VDC power to the PIB and
PDC.
One additional LED (DS3) is for the Patient Data Card Inserted
signal. This is a hardwired signal, regardless of the data on the
Patient Data Card.
Shown in yellow are parts/features identical to the Tina.
15.2.4 PDC System Troubleshooting
For any of the PDC error messages, most likely the problem is the
PDC itself or the information stored on the card. Follow the
operator’s manual to troubleshoot it. Use a working card to
quickly eliminate the PDC as a potential problem source.
Problem Probable Cause Possible Solution
Nothing
happens
when the
PDC is
inserted
Not in the right mode of
operation
Connector on PIB-J1 is
disconnected.
Connectors on PIB-J5 or
SBC parallel port may be
loose or disconnected.
PDC, PIB or SBC
Fuse 2 is open
Verify the Instrument is in the
Prime or Dialysis Mode
Make sure connectors are properly
connected.
Check that the +5 VDC indicator
DS1 LED on PIB is on
Check Fuse #2
Check if the “PDC Inserted” LED
DS3 on PIB turns on when the
PDC is inserted into the PDC
Reader
Try a new PDC Reader
Replace the PIB
Replace SBC
