V883 INSTALLATION MANUAL E L A N H O M E S Y S T E M S

5. Programming

Use VIA!®TOOLS setup software to assign commands to keypads and VIA! Touch Panels. When programming ELAN user interfaces, VIA!TOOLS will automatically configure the video switching commands. Please consult VIA!TOOLS software and the Help file for specific programming steps and full IR, VIA!NET, and RS-232 code sets.

Control Methods

There are three methods of controlling the V883:

•IR

•VIA!NET

•RS-232

Overall system configuration and design goals will determine which programming method should be used.

IR

Use IR commands when controlling the V883 with ELAN keypads or hand-held remote controls.

VIA!NET

Use VIA!NET commands when controlling the V883 with VIA! Touch Panels and

VIA!NET devices like the VIA!SC-4 and VIA!2-SS1.

RS-232

Use RS-232 commands when controlling the V883 from third-party RS-232 controllers or when using a computer to test/verify RS-232 functionality.

V883 RS-232 Protocol

The V883 uses the following communications settings:

•Baud-9.6k or 19.2k (Default)

•8 Data Bits

•1 Stop Bit

•No Parity

•Flow Control-None

Command Structure

•Prefix: Must be present for every command string (Required)

•Command: See list below for all commands (Required)

•Parameter: Decimal value of zone/source command

•Carriage Return: 0x0d or Decimal 13 (Required)

&V883, cmd, par <cr>

•&V883,KEY,xxx<CR> where xxx represents the decimal value of the IR command.

•Unit responds with acknowledgement &V883,ACK,xxx<CR>

•Unit will ignore all characters preceding the ‘&’. It will process and ACK the command as soon as the carriage return has been received.

Note: The V883 requires at least 50ms between each serial command transmitted to it. However, if the &V883,ACK,xxx<CR> is received prior to 50ms, another command can be transmitted immediately.
