Serial Port
(Serial Data Port Parameters)
Description:
The DXP
Plus
provides two serial data ports on the CPU board and dedicates them to PC-based
programming and the remote maintenance modem. You or your installer can add up to 16
additional serial data ports to the system for interfacing such items as open architecture
interface applications, PC attendant positions, and the SMDA data printer. Add these serial data
ports by installing communications cards on the services board, the expansion cabinet interface
board, and the main cabinet’s auxiliary board. Each of these boards will accept two
communications cards in its lower two slots.
The DXP
supports a maximum of 18 serial data ports. Serial data ports 1 and 2 are the
dedicated ports provided by the cpu board while communications cards provide the remaining
16 undedicated ports (serial data ports 3-18). The system designates serial data ports 3-18 to
specific locations as detailed in the following chart.
Serial data
ports 3-10
Lower two slots on the services board
Serial data ports 11-18
Lower two slots on one of the three following locations:
the interface board installed in expansion cabinet 1,
-the interface board installed in expansion cabinet 2,
-the auxiliary board installed in the main cabinet.
* The full compliment of 16 undedicated serial data ports requires four installed
communications cards.
There are programming actions that you take to provide serial data port operation. You must
match the data port number with the installation location that you choose for the
communications card. You can change the baud rates, data bits, stop bits, parity, and flow
control for each serial data port in the system to match the data device that you connect there.
The serial data parameters that you set using this procedure remain in effect until you reprogram
them. The settings will not change even if you perform a master clear of the system.
The maximum available serial data baud rate is dependent upon the location of the
communications card. For cards located on the services board, the maximum baud rate is 19200
baud. For cards located on the auxiliary board or on the interface boards, the maximum baud
rate is 9600 baud.
There are some limitations involved. If a device is transmitting receiving from the DXP
Plus
at a high rate, engineering sources recommend the use of a communications protocol (RTS
CTS or XON XOFF) to prevent buffer overrun and data loss.
