8.4 USING THE SSPA SOFTWARE
The RS-232 and the RS-485 interfaces provide the serial communication between the user’s
monitoring and control system and the micro-controller within an SSPA. The user may employ any
RS-232 terminal communications software (like Term95 or HyperTerminal) or the RS-485 serial
communication protocol.

Before using the RS-232 Interface, become thoroughly familiar with the items listed in
TABLE 11 at page 36 and TABLE 12 at page 38.
Operate the SSPA/system via the RS-232 Interface as follows:
1. Switch on the power station’s circuit breaker to power up the SSPA/system.
2. Run any terminal program in the personal computer.
3. Use the following communication parameters:
- Bits per second: 19200
- Data Bits: 8
- Parity: None
- Stop bits: 1
- Flow Control: None
4. After running the program in the computer and pressing the <Enter> key a display similar to
Figure 4 at page 35 will be shown.
NOTE: The micro-controller within an SSPA determines automatically whether the unit is
functioning alone or in a 1:1 redundant system.
5. If necessary, to change the status of the SSPA/System, use the commands listed in
TABLE 12 at page 38.
