P2 - USB Output Connector

The connector configuration permits the controller to be placed in-line between the touchscreen and a USB hub or host attachment.

The USB connector, P2, is a USB Series "B" receptacle as specified in section 6.5 of the USB specification, version 1.1. The pins are numbered as shown in Figure 1.

P4 - Power Connector

Table 2. Power Connector

Signal name	P3 pin 1	Signal function	W1 Position
+Regulated Pwr	1	+5 volts DC +/- 5%	Off - Self Powered
Pwr Com	2	Supply voltage common	Off - Self Powered
n/c	1	USB Vbus	On - Bus Powered 2
n/c	2	GND	On - Bus Powered 2

¹ P3 mating connector is a Molex 22-01-3027 with Pins 08-50-0114.
² Bus powered option is not compliant with stringent USB Suspend Mode requirements.

A green LED (D2) 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 (D1) 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

• Elo controllers are "CNR/USR" UL Recognized Components for USA and Canada, Category NWGQ2, Information Technology Equipment Including Business Equipment.
