Troubleshooting:
In many cases, problems encountered when installing
MultiView™ II extension products can
be resolved by checking the CAT5 cable termination. It must be pinned out according to the TIA/EIA 568B
standard wiring specification. For additional troubleshooting information or to obtain the TIA/EIA 568B wiring
specifications please refer to the MVII-AK1200 User Guide, downloadable from
