(*1) CRC: Cyclic Redundancy Check
A data error detection method widely used in synchronous transmission.
(*2) Since the station number of the master is normally set to 0, the setting range is 1 to 64. The number of stations,
including occupied stations, must not exceed 64.
(*3) The GateWayR unit and master communicate with each other when the master is in the online mode. In the
online mode, the MODE switch on the master is set to any one of 0 to 4 (when QJ61BT11N is used).
Condition
[1] Normal
[2] Reset process is in progress.
[1] CRC error
[2] A station number setting error
occurred after a reset.
[3] A baud rate setting error occurred
after a reset.
The station number or baud rate changed
from the specified value after a reset.
[1] Refresh or polling data was received
successfully after joining the network.
[2] Refresh data was received
successfully.
[1] The unit is yet to join the network.
[2] Channel carrier waves were detected.

(*3)
-
-
This condition indicates that the unit is
offline, meaning that it is not linked to the
host master.
Check the power supplies of the master
and gateway unit, communication cable,
station number and baud rate settings of
the gateway unit, and network parameter
settings of the master.
