You can use a short haul modem or line driver to extend the distance the 
apC/8X can be located from the host. For information about connecting a 
modem to the host, see the appropriate documentation for your modem.

Note: Short haul modems and line drivers have not been evaluated by 

UL for use with the apC/8X.
