Marquette Hellige GmbH CORINA Page 24
Version 2.0 227 437 01 D
3.4.2 Electrical Interfaces
CORINA has two external interfaces. These are:
- interface to PC
- ECG input
- optional: Analog Out
3.4.2.1 Interface to PC:
Data interface:
Description of interface:
OUT(0-5) data to PC
OUT6/ACK data bit to PC and data acceptance confirmation
this interface lead fulfils two functions
READ MODE -> data line D6 (data from CORINA -> PC)
WRITE MODE -> ACK* (data from PC -> CORINA)
For outputs OUT(0), OUT(1) and OUT(3) it is important to observe that these are output
inverted by CORINA since, initially, the PC inverts these inputs.
In newer CORINA versions (101 118 31...36 and 101 118 41...44 a new cable to PC is
used, where only OUT (2, 4, 5) are used to transmit data to the PC.
ERROR* indicates “full or empty FIFO“
IN(0-3) data from PC
ES selection whether ERROR* should indicate “full or empty FIFO“
ES = LOW -> CORINA indicates “empt“ FIFO
ES = HIGH -> CORINA indicates “full“ FIFO
READ* transmit data to PC
WRITE* read data from PC
ON switch on CORINA
ON = LOW -> CORINA is switched off
ON = HIGH -> CORINA is switched on
