Room Status Property Management System - Communication Interface
Updating Room Status Information in the NEAX
The messages containing room status information, sent from the PMS, are as
follows:
Check In: 16-1, 16-A, 16-B, 56-1
Check Out: 16-2, 56-2
Room Change: 20-1, 56-6
Room Data Image: 17-3, 17-7, 17-B
Maid Status Answer: 51-9
Check In Cancel: 56-4
Room Data Change: 61-1
Room Status Change: 61-3
Check Out Cancel: 56-5
Recovery Room Data Report: 57-1.
When updating the room status from the NEAX side, the update is performed as
follows:
The validity of maid status messages (11-1, 11-2, 11-3, 12-1, 12-2, 12-3) is
checked by the room status stored in the NEAX. After the status of the room has
been updated, maid status messages are sent out to the PMS.
Maid Status Answer Back System: maid status messages are sent out to the PMS.
The PMS will then check the validity of the messages and provide either a positive
or negative result to the NEAX. This is used in Model 90 only.
For messages in Model 90, the Room Status field and the Cleaning Status field are
provided so that details can be directed to the PMS. If certain hotels do not utilize
maid status for their applications, the status can be designated as Vacant in the
Check Out message.
Clearing Room Data
The NEAX will clear the room data when the PMS sets the status of the room to
“Vacant (Room Status=0, Cleaning Status=3)” or “Out of Order (Room Status=0,
Cleaning Status=4)”. (Note: Group Registration is cleared at the time of Check
Out.) Therefore, in a hotel where the PMS does not provide maid status, the PMS
must use a Check Out message to make the status of the room become “Vacant”,
and thus clear the room data.
Dial Steps for Maid Status
A choice of three dialing patterns is available for Maid Status in the NEAX.
Whichever pattern is selected, the “Inspection End” step must be included.
