HARACTER
If you allow this option to have a character value (the range is 0 to 255
decimal, 00 to FF hex, or 256 = disabled), the TEP will not recognize a record
as having begun, nor will it recognize an “end-of-record” character (see
below) or “no-receive delay,” until it senses the character you select. The TEP
will begin counting record length after sensing this character. You can set the
TEP’s system switch SWF to either pass or discard data received before the
beginning-of-record character (see
Section 3.1.2.H
). The factory default for
this selectable-by-port option is “disabled.”
This character can be used even if the end-of-record character is disabled.
Records can be terminated by the “no-receive delay” timeout or by the
maximum-record-length restriction.

HARACTER
If you allow this option to have a character value (the range is 0 to 255
decimal, 00 to FF hex, or 256 = disabled), then, when the TEP is receiving a
slave’s record and senses the character you select, it will treat the record as
having ended at that point. The factory default for this selectable-by-port
option is 13 decimal, 0D hex (the ASCII carriage return).
If you disable this character for a given port, do not also disable both the
“no-receive delay” timeout and the maximum record length for that port.
When it’s in either Concentrate mode, the TEP will not transmit slave data to
the master unless the data is in the form of a complete, valid record, which
can never happen if all of these delimiters are disabled.

If you allow this option to have a value other than [NULL] (the range is 0 to
16 printable characters), the TEP will precede records from the selected slave
port with the label you enter. Refer to
Section 5.5.4.B
. The factory defaults for
this selectable-by-port option are “P1 ” for port 1, “P2 ” for port 2, etc., up to
“P4 ” for port 4 (or “P8 ” for port 8 if you’ve installed the 4-Port Expansion
Board).
