TRANSMITTED DATA FORMAT
Acknowledge
The explicit characters "OK" acknowledge receipt of a valid message, followed by 11 spaces (not counting
the space for line continuation, described below).
Error
The line begins with the character "E", followed by a 3-digit decimal value defining the error number. It is
up to the user to provide necessary messages defining the error, if desired. A full listing and description of
error numbers is provided in a later section of this document.
An "equals sign" ("=") follows, and is then followed by a "plus" ("+") and 7-digit explanation code. For
character-traceable errors, the number indicates the column position of the character which resulted in the
error. Positions are numbered 0-127, 0 representing the first character and 127 the last permissible
character. If the error is due to a general error (e.g., "LINE TOO LONG"), the character-trace code is 128.
Example A:
Received
string: START
Transmitted
string: E030=+0000128!<CR>
(Error 30 = "Unit Not in Remote")
Example B:
Received
string: SP=25 CPB=2.5 IT=35,0 DT=6
Transmitted
message: E021=+0000019!<CR>
(Error 21, Illegal character, in position 19)
VALUE
The line begins with the character "F" (Function), followed by a 3-digit decimal code defining the opcode
number assigned to the parameter.
Following the function code is an "equals sign" and an 8-character value. This value will ALWAYS begin
with a polarity sign ("+" or "-"), followed by either a) 7 digits; or b) 6 digits with an embedded decimal
point.
The value 0 will always be "positive".
All temperatures are internally resolved to 0.01 degrees F. Temperature values will always be returned
with full resolution on the RS-232 regardless of the resolution of the control panel display or the user
display options. Temperature values will be transmitted to the host in the units (C, F, K scale) selected by
the DEGREES= command (or via the dEG setting in the control panel “Etc” menu).
Values for system characteristics which are not programmable parameters: e.g.: switches, on/off status, etc.,
will be returned as byte status. In other words, if the state is "true", the returned value will be +0000255
(byte true hex FF); if the queried status is false, or off, the returned value will be +0000000 (byte false hex
00).
