The DS-Micro switch is a compact matrix switch contained within a 1u high 19” custom built housing. Each mini switch is designed to house a maximum of 4 two channel port cards although the unit can be sub-equipped for smaller capacity systems. There is only one variety of switch cards in the system and they can be programmed to be either a channel port, or an operator port. The cards operate using our own DSP software code which greatly reduces the component count, thus providing a very cost effective method of providing a multi operator, multi channel control system.
