Power Connector, P4

The power connector, P4, is a 2 row by five-position header with 0.025-inch pins on 0.100 centers. The header is compatible with insulation displacement cable (IDC) connectors such as Berg series 71600, series 71602, series 66900, and series 66902, Molex style 40312, Amp series 746285 and series 746288 receptacles. The header is also compatible with crimp termination, discrete wire receptacles and housings including Berg Mini-Latch housings and Mini-PV receptacles, Molex series 70450 connectors, and the Amp AMPMODU Mod. IV connector family. Pin numbering schemes for discrete wire connectors differ between manufacturers.

Refer to Figure 3 for pin number locations. Signal connections are shown in Table 3.

LED Diagnostic Characteristics

A green LED (D1) indicates controller status as follows:

LED Blink Rate	Function
Once per second	Normal condition, untouched state
On continuously	Touched state
Twice per second	Error detected

A second LED (D6) indicates USB status as follows:

LED State	Function
OFF	Controller is not enumerated on USB
ON	Controller is enumerated on USB, but there is no data transfer
Blinking	USB data transfers between controller and host are occurring
