with a CRC-7 at the end of the message.
•
User Defined (16 byte): Selects a 16-byte user-
defined ASCII message as the transmitted trace
pattern. The message is entered and saved using a
touch screen keyboard. The user-defined message
can be up to 15 ASCII characters, appended with a
CRC-7 at the end of the message.
•
All 01's - Selects an All Ones (0x01) hexadecimal
pattern as the transmitted trace pattern. The 0x01 byte
value repeats indefinitely and does not contain CRC-7.
•
All 00's - Selects an All Zeros (0x00) hexadecimal
pattern as the transmitted trace pattern. The 0x00 byte
value repeats indefinitely and does not contain CRC-7.
•
User Defined (1 byte): Selects a user-defined
Hexadecimal byte value as the transmitted trace
pattern. The byte value is entered and saved using a
touch screen keypad (from 0x00 to 0xFF). The byte
value repeats indefinitely and does not contain CRC-7.
The J1 trace is part of the HP Overhead and is known as
the Path trace or the J1 byte.
The J2 Trace is a repeating 64-byte, 16-byte or 1-byte
pattern that can be configured to send the system's default
ASCII pattern, a customized user-defined ASCII pattern, or a
1-byte hexadecimal pattern.
The following options are available:
•
Default (64 byte) - Selects the default 64-byte ASCII
message as the transmitted trace pattern. The
message consists of 62 ASCII characters appended
with CR and LF characters at the end of the message.
•
User Defined (64 byte) - Selects a 64-byte user-
defined ASCII message as the transmitted trace
pattern. The message is entered and saved using a
touch screen keyboard. The user-defined message
can be up to 62 ASCII characters, appended with CR
and LF characters at the end of the message.
•
Default (16 byte): Selects the default 16-byte ASCII
message as the transmitted trace pattern. The
message consists of 15 ASCII characters, appended
with a CRC-7 at the end of the message.
