Module interface socket pin definition 

The pin definitions are shown in the table below: 

Note: 1. TXD is the data sent by the CO/IBP module to the host, in TTL level mode.

2. The J1, J2, and J3 sockets use the 2.0 spacing specification, and the J4 socket uses the 2.54 spacing specification. 

Module and External Connector Description 

Signal input interface of IBP1

J1 is the 4Pins connection port, two of which are the pressure output terminals IBP1+ and IBP1-, pay attention to the polarity of the signal connection; The other two are DC power supplies.

Signal input interface of IBP2

J2 is the 4Pins connection port, two of which are the pressure output terminals IBP2+ and IBP2-, pay attention to the polarity of the signal connection; The other two are DC power supplies.

Interface of digital signal input and power input

J3 is a 4Pins connection port, two of which are serial transceivers TXD and RXD, TTL level; the other two are direct current power input.

Signal input interface for CO

J4 is the 5Pins connection port, of which 1 and 2 are the injection temperature signal port, 3 and 4 are the blood temperature signal port, 5 is the input end of the temperature calibration signal, and 2 and 4 are the two ground terminals (which are common).
