Important Operation Notes
1. When a PPS is not connected, connect the PPS header pin to ground.
2. When RB0 is high, the PMU will continously transmit data after resets using the RB1, RB2, and RB3 pin settings
When RB0 is low (grounded), the RB1, RB2, and RB3 pin settings are ignored.
*** If you are not using the RB1, RB2, and RB3 pins, Then Connect RB0 to Ground ***
A. Set RB1 high for Text mode. Set RB1 low for IEEE C37.118 mode
B. Set RB2 high for PPS mode, set RB3 high for GPS Time mode. Set RB2 and RB3 low for GPS Not Used mode.
C. You can set these high impedence input pins high by jumper wire to any +5Vdc pin
D. You can set these high impedence input pins low by jumper to any ground pin.
3. Probes connected directly to the INT1 and INT2 header pins may have adverse affects on phase measurements.
A. 0.1uF bypass capacitors may help
