ERROR RESPONSE CODES

The following lists the possible error codes that will be returned with the
ERROR RESPONSE when an error occurs. Macro response errors are listed in
Paragraph 6.3.

CODE DESCRIPTION AND SOLUTION

0001

The command was timed out by the HIU function. The NM function is
possibly offline due to a malfunction or its maximum poll delay is longer
than the host command timeout in the HIU. This error could be the
result of a global connect or global disconnect.

0002

A TIWAY I HDLC error occurred with the addressed secondary that
could not be corrected. Reset the secondary device.

0003

The wrong secondary device address was returned to the HIU in the
response. Reissue the command. If this error continues to occur, you
will need to reset the Network Manager which also resets the TIWAY I
network.

0006

The command string tried to use secondary address 00. Retransmit the
command with the correct secondary address.

0008

The NM could not process the stream of bits from the secondary fast
enough. Resetting the adapter with the NM function should clear this
problem. If this error continues to be returned, report this problem by
calling the Texas Instruments Technical Services Hotline at
615/461–2501.

0009

The adapter continued to receive an incorrect HDLC Block Checksum
from the secondary after the maximum number of retries.

000A

The secondary timed out in the middle of the message.

000B

The secondary device timed out because the maximum poll time
expired. The value for the maximum poll time may need to be adjusted.
This is described in the syntax reference for command code 30 in
Chapter 5.
