Error “1” – Invalid checksum. This error means either the checksum you sent was
wrong or the transmission was bad due to interference (double check your
checksum calculation or your serial link).
Error “2” – Invalid Incoming Packet ID (i.e. Command = “3”&”0”, Query = “2”&“0”,
others are invalid when sent to the iScan)
Error “3” – Invalid Setting (i.e. Power = “A”&”1”) if you get this error, make sure that
the command is supported by the model you are using.
Error “4” – Range Error (i.e. Power on = “1”, power off = “0”) if you get this error you
tried to set a value to the control which is either out of range or not
supported.
Error “5” – Bad Packet Character (i.e. STX, ETX, NUL) a valid ASCII character value
may have been used in the wrong place – double check your syntax.
Otherwise, ensure that only numbers, or punctuation (“.”, “+”, or “-“) was
used.
Error “6” – Last byte of packet was not received within 100 milliseconds – if this
happens, first make sure that the link is good. Then, ensure that your control
device is waiting for a complete response packet before sending another
packet. If your controller does not “listen” to the flow control pins
(DSR/DTR look at section 2.1) the buffer may over-flow causing bytes to be
lost. If no RS-232 return path is being used, pace your commands to about
10 commands every second.
Error “7” – Unterminated Data Value. This means you missed a “NUL” after a value
and went straight to the “ETX” – check your syntax.
Error “8” – Bad Data – If you get this response, first check your serial link, then check
the table in Section 3 to ensure you sent the right type of value. If you send
a “5E” for a control expecting a number like “1.453”, you will get this type
of error response.
Error “9” – Too many or too few data characters. This error appears if your packet has
the wrong byte counts value, or you don’t have all of the data in the string.
Error “10” – The setting is not writable (i.e. command for “Device Name”), this will be
your response if you attempt to write to a query only Command ID
Error “11” – The packet is larger than the maximum packet size. You should never see
this error – we do not have any controls which are at the time of this writing
even close to the maximum size. If this error comes back – check your
serial link and syntax. If you are transmitting more that 50 bytes in a single
command you are probably doing something wrong!!
