Notes:

1.The module signal ground pins, VeeR and VeeT, shall be isolated from the module case.

2.This pin is an open collector/drain output pin and shall be pulled up with 4.7k-10k ohms to Host_Vcc on the host board. Pull ups can be connected to multiple power supplies, however the host board design shall ensure that no module pin has voltage exceeding module VccT/R + 0.5V.

3.This pin is an open collector/drain input pin and shall be pulled up with 4.7k-10k ohms to VccT in the Module.

4.This pin shall be pulled up with 4.7k-10k ohms to Host_Vcc on the host board.
