I am having problems with the Vd power on the new Buffalo32s. I have the voltage on the dual supply set to 5 volts for both outputs. I have a 4:1 Mux on one, and the buffalo connected to the other. When I power up, the voltage on the Buffalo Vd, drops to 1.6 volts. If I swap the Mux and the Buffalo, on the power supply, I get the same thing. If I disconnect the Buffalo, I still get 5 volts from the supply. So, it appears the supply is OK, Any ideas as to what the problem may be.
Thanks

Take a look at the firmware uC on the Buffalo (IC8, near the dip switches). The dot on the chip should be facing the outside edge of the board. If not, gently pop it out ( a small screw driver can be used to coax it out a little at a time) and spin it around.

The chip was backwards, I flipped it, and all is well. Thanks for the prompt response.
