4.1 SPA setting The most important settings in the terminal for SPA communication are
the slave number and baud rate (communication speed). These settings are
absolutely essential for all communication contact to the terminal.
These settings can only be done on the built-in MMI for rear channel
communication at:
Configuration
SPAComm
Rear
and for front connection at:
Configuration
SPAComm
Front
The slave number can be set to any value from 1 to 899, as long as the
slave number is unique within the used SPA loop.
The baud rate, that is, the communication speed, can be set to between
300 and 38400 bits/s. The baud rate should be the same for the whole sta-
tion, although different baud rates in a loop are possible. If different baud
rates in the same fibre optical loop are used, consider this when making
the communication setup in the communication master, that is, the PC.
The maximum baud rate of the front connection is limited to 9600 bit/s.
For local communication, 19200 or 38400 is the normal setting. If tele-
phone communication is used, the communication speed depends on the
quality of the connection and on the type of modem used. But remember
that the terminal does not adapt its speed to the actual communication
conditions, because the speed is set on the MMI of the terminal.
