Start transmission (STX):
When enabled, GW PN/ASCII... adds an STX (start of
transmission) byte sequence which is configured as
one byte
or
two bytes
when it
transmits a serial packet. If
none
is selected, the feature is disabled. If
one byte
is
selected, the GW PN/ASCII... adds one byte the beginning of the packet. If
two bytes
is
selected, the GW PN/ASCII... appends two bytes.
–
Byte 1:
Specifies the character that represents the first STX byte. The GW PN/ASCII...
appends this byte if the length is one byte or two bytes. Specify a value between
0
and
FF
in hexadecimal format.
–
Byte 2:
Specifies the character that represents the second STX byte. The
GW PN/ASCII... adds this byte only if the length is two bytes. Specify a value between
0
and
FF
in hexadecimal format.
End transmission (ETX):
When enabled, the GW PN/ASCII... adds an ETX (end of
transmission) byte sequence that is configured as
one byte
or
two bytes
marking the end
of the serial packet. The length indicates the number of ETX bytes; if
none
is selected, this
function is disabled. If
one byte
is selected, one ETX byte is appended to identify the end
of a serial packet. If
two bytes
is selected, two ETX bytes are appended to identify the end
of a serial packet.
–
Byte 1:
Specifies the character that represents the first ETX byte. The GW PN/ASCII...
appends this byte if the length is one byte or two bytes. Specify a value between
0
and
FF
in hexadecimal format.
–
Byte 2:
Specifies the character that represents the second ETX byte. The
GW PN/ASCII... adds this byte only if the length is two bytes. Specify a value between
0
and
FF
in hexadecimal format.
