has designed modems that work in "remote" remote sites with very low failure rates. These devices work where other modems roll over and die. When a service call to a remote site can mean an all day trip these modems are the ideal solution.

The MIU/PowerPort is an industrial grade modem that can be powered directly through the RS232 (DB25) data interface port or power jack.

MIU/PowerPort can be powered by delivering +5VDC (regulated) through pin 10 of the DB25. An optional 12VDC version is also available. Alternatively, an external jack allows the MIU/PowerPort to be powered from a wall transformer or other low voltage AC or DC power source.

When not on line, the dial up MIU/PowerPort modems automatically go into a power down mode and consumes only 5m amps while inactive.

The MIU/PowerPort is available with various modulations, including...

...and operates over dial-up and 2 or 4-wire leased lines at full or half duplex as appropriate.

The MIU/PowerPort has a sister product, the MIU/PowerPack, which is powered from an internal, rechargeable Ni-Cad battery. The battery draws its charging current from the DTE’s RS232 interface or an optional solar panel. For more information, ask for the MIU/PowerPack brochure and specifications.

The MIU/PowerPort is fully Hayes AT command set compatible with programmable S-registers.

All models will operate in temperatures from -40 to 85oC and are surge protected on the analog line up to 5kV.
