Notes:

1. The module 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-10Kohms to a Host_Vcc on the host

board.

3. Shall be pulled up with 4.7K-10Kohms to VccT in the module.

4. This pin is an open collector/drain input pin and shall be pulled up with 4.7K-10Kohms to VccT in the module.
