TOA VS-900 Programmer’s Guide

Overview

Security system installations often require integration of the VS-900 Security Intercom systems with touch-screen control systems, graphic annunciator panels, and camera controllers. TOA offers two options for meeting this requirement:

1.The VS-900DI and VS-910DI interface products offer a hardware solution—they provide the call LED outputs and select switch inputs required for graphic annunciator panels. They also provide relay outputs for camera switcher integration. Using this off-the-shelf method requires no knowledge of computer programming or serial communication.

2.The VS-900MF Mainframe has two integral serial ports for integration with a microprocessor-based product (usually a PC or PLC) for remote control and monitoring of VS-900 activity. Serial communication with the VS-900MF eliminates the need for installing VS-900DI and VS-910DI cards and elevates the programmer's level of control.

This document targets programmers who need an understanding of how they can remote control and monitor the VS-900 by communicating through its RS-232 ports.

Note: Descriptions of the protocol and all examples are written in hexadecimal (H). Appendix B includes a chart for hex to decimal and ASCII conversion.
