Property Management System (PMS) Interface
— PMS Link Maximum Retransmissions
Enter the number of times (1 to 5) that the server will retransmit a
message in response to a negative acknowledgment, or send an
inquiry for an acknowledgment from the PMS for a message
before giving up on the message transmission. The recommended
setting is 5. Consult the PMS vendor about this setting.
— PMS Link Maximum Retransmission Requests
Enter the number of times (1 to 5) that the switch will request the
PMS to retransmit a message. The recommended setting is 5.
Consult the PMS vendor about this setting.
— Take Down Link for Lost Messages
Enter y to cause the server to take the PMS link down if a mes-
sage is sent and rejected for the number of times specified in the
PMS Link Maximum Retransmissions field. An n in this field
causes the server to leave the PMS link up, but the PMS will stop
trying to send the message. Careful monitoring of the PMS log is
recommended when set to n. The recommended setting is y.
The database swap between the server and the PMS may not be
complete if they are out of synchronization. Choosing to disable
the link allows the PMS to function with partially correct data. Tak-
ing down the link forces a database swap. The reason why the
server and the PMS are out of synchronization must be deter-
mined and corrected.
Required Hardware 0
The PMS interfaces to the communications server through a data module
(8400B plus or 7400A) connected to a digital port (TN2214 or TN754B). Unless
otherwise instructed by the PMS vendor, set the data module speed at 9600 bps
for Transparent Mode or ASCII Mode and 1200 bps for Normal Mode.
