POWER SUPPLY

Using an external power supply is optional on USB

applications but

essential for RS232 and RS485 applications.

• When used, the external power supply should be

connected to the 5V connector (CONN3).

• Near this 5V connector there is the 'LK1' jumper,

and rightwards there is the LK5 jumper:

* Option 1: 5V from the USB port

Put the 'LK1' & ‘LK5’ jumpers in the 'USB' side.

* Option 2: External 5V supply

Put the ‘LK1’ jumper in the 'DC JACK' side.

Put the ‘LK5’ jumper in the 'NOT USB' side.

The external supply should be 5V DC (±5%) only.

* Using USB hubs

The TCIC may be connected to a USB hub provided

that:

Either

1. The USB hub is externally powered such that the USB ports

of the hub meet the standard USB power specification.

In this case use option 1.

2. A bus powered USB hub (with no external supply to the

hub) is used but the TCIC takes its power from the TCIC

DC jack. In this case use option 2.
