Switch Interface 32

An easy way to automatically update electronic message centers used in conjunction with Venus® 1500 software. Parking facilities use the SI-32 to update information such as parking space status, toll displays, open/closed lanes, and more.

How It Works

  1. Switches connect to the SI-32. A computer running Venus® 1500 software connects to the SI-32, and the SI-32 connects to a display.

  2. Once the messages are created or edited with Venus® 1500 and loaded in the Galaxy® sign memory, the PC running Venus® 1500 can be disconnected from the system.

  3. Up to 32 switches (in many forms, such as motion sensors, time, date, event/count triggered PCL relays, or simple contact switch closures) connected to the SI-32 make up to 240 signs update accordingly.

Switch Modes

Single Pole Switch/Relay Mode
Once a switch is closed, the corresponding message runs continuously until that switch is turned off

Momentary Switch/Relay Mode
Once a switch is momentarily closed, the corresponding message runs once

BCD Switch Mode
Once a switch number is selected, the message runs until another switch number is selected

Features/Benefits

    • When selecting multiple switches, multiple messages run in the chosen order
    • Uses many different switch types
    • Compatible with many different Venus® 1500 controlled display sizes and technologies
