Mounting and Connecting the SAS-Junction Box (SAS-JB)
Multiple SAS-1 units may be connected to a single cabinet controller and communicate over a
single home run link using RS-422 or wireless. When using a cabinet controller such as
SmarTek Systems’ T-BOX, the number of SAS-1 units connected via a single home run cable is
only limited by power supply considerations and the communication polling period. When
connected via wireless, the number of SAS-1 units that share the same wireless link is only
limited by the communication polling period.
