Status bits

Packets sent in response to commands always contain 4

StatusBits

. The following table defines

the meanings of these bits.

Bit

Name

Meaning

Not used

MASKBITWARNING

If the value is 1, a message is waiting for the master.

Not used

MASKBITNODIN

If the value is 1, the terminal is responding to the
default command with the status of its overrides and
control knob. If the value is 0, the terminal is
responding with the status of its keys.

Invalid command response

Whenever the terminal cannot implement a command, it sends the following response.

Byte

0x0

StatusBit

CmdNACK

Byte 05 of sent command

Byte 06 of sent command

Byte 07 of sent command

CRC

ETX

Example:

The master sends a read command to the terminal at node address 0, but the command

packet contains an error, e.g. it is too long. The terminal responds with

CmdNACK
