To input a custom heartbeat packet:

c and press Enter. You are prompted for the length of the packet
including header bytes and CRC bytes.
2. Enter the length of your custom packet in decimal format and press Enter.
You are prompted for each packet byte.
3. Enter packet bytes in Hex format in the following order:
MAC DA Net Optics (6 bytes)
MAC SA Net Optics (6 bytes)
Packet Type (2 bytes)
Packet Bytes
CRC (4 bytes)
Alternately you can load the packet as a pre-formatted text le. The text
le must be one byte per line beginning with a decimal value for the num-
ber of packets followed by hex values for the remaining bytes. Load the
text le at the packet length prompt.
To load a packet from a le, you must set the Line Delay to 1000 millisec-
onds and the Character Delay to 100 milliseconds in your terminal emula-
tion software. If you are using HyperTerminal, these settings are located
in the ASCII Setup dialog box found in File>Properties>Settings>ASCII
Setup.
To display the current values:
1. Type
d and press Enter. A list similar to the following appears.
