2.1.1 Power

USB High power ports can supply 500mA of power. Low power devices, such as un-powered hubs,

can only supply 150mA of power. Please be sure to observe the total power usage on the display when

connected to the USB port. The display will require between 150mA to 250mA depending on the model and

the number of GPOs being used.

Table 3: GPO Power Levels

GPO Maximum Power

+5V Low Power 20mA

+5V High Power 1000mA. Please note; an unmod-

iﬁed USB host can only supply

a maximum of 500mA on a high

power output and only 150mA on

low power.

+12V High Power 1000mA

Power is applied via the USB cable or the alternate USB header. Power requirement is +5 VDC ±0.25V

and 180mA minimum.

WARNINGS

• When using the alternate USB header, verify all the cable pin outs

before applying power. Incorrect power application may damage

the display on one host.

• Make sure the host is capable of supplying all the necessary power.

Add the display power requirement and the GPO power if used for

a total power requirement.
