RS-232 Communications
Baud rate: 9600 (fixed)
Bits: 8
No Parity
All protocol in ASCII format
RS-232 input connector pin numbers: TxD= Pin# 2, RxD= Pin# 3, GnD= Pin# 5
Command format (single command): command value (i.e. brightness 30).
NO
TE: A space (not an underscore) or comma may be used between the command and its value.
Command string format: command,command value, command etc.
(i.e. COMPOSITE,BRIGHTNESS 30,ANAMORPHIC,<CR>)
NO
TE:
In between commands, a comma must be used; a comma or space may be used in between
a command and its value.
NO
TE: A carriage return must be used after each command or string.
Other notes:
• For command strings, a maximum of 255 characters can be used in a single string.
• If it is necessary to input multiple commands, they should all be together in a single string. Inputting
commands one at a time requires a 15 second delay between commands, as the information is
stored into non-volatile memory after each command.
• For values not automatically stored (see next paragraph), the command "!STORE" must be sent
in order for the PFP Controller to keep the settings. Otherwise, the values will be considered
temporary and will revert to their stored settings upon source change or power-up.
• The "Value stored" column refers to a command that is either automatically stored or if it must be
manually stored with the "!STORE" command.
• PARAMETER min/max refers to a function's minimum and maximum value range. Inputting
values above or below their range may cause unpredictable (but not fatal) results.
• When connecting RS-232 to the Controller, you may have to add a delay in between characters.
For example in an AMX system you would add the following line:
(***********************************************************)
(* STARTUP CODE GOES BELOW *)
(***********************************************************)
DEFINE_START
SEND_COMMAND PFP,'SET BAUD 9600,N,8,1'
SEND_COMMAND PFP,'HSOFF'
SEND_COMMAND PFP,"'CHARD-200'" (* SETS DELAY IN MICROSECONDS BETWEEN CHARACTERS *)
This will increase the reliability in receiving the code. For other systems you may have to contact the
manufacturer to find out how to set the delay.
