V883 INSTALLATION MANUAL
©
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
• &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.
&V883, cmd, par <cr>
• 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)
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.
