Switch Interface 32

What is the SI-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.
