Presidor™

Presidor™ Room Linker/Combiner (PRLC-4) is an intelligent multi-port DMX512 merger designed as the "hub" for the Presidor™ Wall Stations (PWS). PRLC-4 will allow input streams of DMX512 data to be merged when contact inputs are "patched" to create a larger room/zone. Each PRLC-4 will support up to 4 rooms/zones of PWS wall stations (DMX512) with isolated DMX inputs and an integrated 48VDC power supply to each room/zone. Multiple PRLC-4's (maximum 8) can be cascaded together with RJ45 connection to permit up to 25 rooms/zones of PWS controls merged into a single DMX512 output. Field connections are either via RJ45 with Cat5/5e/6 wiring or terminal block over existing Belden 9773 wiring. Four (4) programmable maintained dry-contact inputs permit PWS (Presidor™ Wall Station) linking in any possible room/zone combination. At only 1RU in height the PRLC-4 will fit in any standard 19" rack or can be supplied with a small purpose built 19" wall mount rack (PRLCR-4U).

Johnson Systems Inc. (JSI) expands architectural control capabilities.

JSI is pleased to announce that we are now shipping the Presidor Room Linker GUI. This version of Presidor Wall Station (PWS-RDU) is designed to permit ease of room linking and labeling in multi-room flex spaces. This touch screen interface is fully programming for control up to 25 rooms/zones and any combination of multiple room-links including room overlap and room within a room.

Designed to plug directly into our Presidor Room Linker/Combiner (PRLC-4) this new product provides enhanced capabilities beyond the existing dry contact inputs on the PRLC-4.

"This new graphic touch interface and display provides unique user-friendly capabilities and unmatched value for single DMX universe multi-room applications such as convention and hotel meeting facilities, large dining spaces and flex space areas", states JSI Owner and Founder Shaun Johnson.
