Connection on the Remote ½ port is BUS CAN, where all devices can be connected using daisy-chain mode. Maximum length from the REMOTE port to last device can be up to 800m with CAT5 cable. Powering all paging stations and remote controls can be done using REMOTE port, but in longer distances or with high number of devices connected, an additional power supply should be implemented. To calculate how many power supplies are required, use our calculator. In MPAGE paging stations the limitation is caused by the microphone signal, balanced or analog (see manual), which is connected between MPAGE16 paging station and input on MIMO.
