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-10kohms 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 + 0.5 V.
3.This pin is an open collector/drain input pin and shall be pulled up with 4.7k-10kohms to VccT in the module.
4.See SFF-8431 4.2 2-wire Electrical Specifications.
5.This pin shall be pulled up with 4.7k-10kohms to Host_Vcc on the host board
