A4683

Indicates the application id number. This is copied from the application id field of
O4683 after a successful download.

P4683

Indicates the parameter id number. This is copied from the parameter id field of
O4683 after a successful parameter download.

L4683

Indicates the RS232 port configuration. This is known as the line configuration for
the port and is only valid if I4683 is set to R232. It is a 13 byte string with the
following format
COM port B
COM port
B
Baud Rate
Word Size
Parity
Stop Bits
Auto Enable
RTS
NOTE
L4683 must be set if I4683 is configured for R232.
All padding bytes should be spaces (0x20). If the baud rate is less than 6 bytes,
then it should be followed by padding bytes. Auto Enable and RTS should be set
to uppercase "A" and "R", respectively. Parity should also be signified with an
uppercase letter of "E", "N" or "O". The entire string must be a minimum of 11
bytes – the Auto Enable and RTS are optional. However, if RTS is specified and
Auto Enable is not, then there should be a pad byte (space – 0x20) for Auto
Enable before the RTS "R" is specified. COM 1, 2 and 3 all have flow control
capability.
