2. +5VDC Power Jack

The iPort Host Adapter can be powered in one of two ways, from

the power jack, or from the I

C interface connector. If the unit is

powered from the provided +5VDC Wall Transformer,

approximately 250ma of regulated +5VDC is available at the I

interface connector to power external devices. If the iPort is

powered from the I

C connector, the unit requires 50ma of

regulated +5VDC.

3. I

C Interface Connector

The iPort Host Adapter includes a four wire, positive locking,

modular connector (see Appendix A for more info on these parts)

for interfacing to an external I

C Bus. Lines provided include I

Clock (SCL), Data (SDA), Ground, and +5VDC.

Receptacle Connector

An I

C Interface Cable (White=SCL, Red=+5VDC, Green=SDA,

Black=Ground) is provided to connect to a external I

C Bus. Since

there is no standard I

C Bus connector, you may want to cut off

one end of the cable and add a connector compatible with your

target system.

Additional I

C Interface Cables (4 ft., 8ft., or 16 ft.) and above

mentioned modular connectors are available from MCC. Clip Lead

cables are also available. (see Appendix A)
