8.6 USING THE SSPB 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 a Up-Converter. The user may
employ any RS-232 terminal communications software (like Term95 or HyperTerminal) or the
RS-485 serial communication protocol.

NTERFACE
Before using the RS-232 Interface, become thoroughly familiar with the items listed in
TABLE 11
at page 36 and
TABLE 12
at page 39.
Operate the SSPB/system via the RS-232 Interface as follows:
1. Switch on the power station’s circuit breaker to power up the SSPB/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 starting the communication program (Term95 or HyperTerminal), press ‘
t2
’ (for PC
terminal) and then the <
ENTER>
key. A display similar to
Figure 4
at page 35 will be
shown.
NOTE:
The micro-controller within an SSPB Block Up-Converter determines
automatically whether the unit is functioning alone or in a 1:1 redundant
system.
5.
If necessary, to change the status of the SSPB/System, use the commands listed in
TABLE 12
at page 39.
NOTE:
At start up the SSPB unit is in the hand-held Terminal Mode. To change to
PC Mode, type ‘t2’ and then press <ENTER>. For operation with the Hand
Held Terminal type ‘t1’.
If the Hand Held Terminal model 8045 is used for the RS-232 communication with the unit, the
adequate configuration should be set. In order to set the configuration:
- While simultaneously pressing the CTRL, SHIFT keys press the F1 key.
- In the menu displayed use F1 key to change parameters, F2 & F3 keys to navigate, F4
key to quit (without changing parameters) and F5 key to save the changed values for
parameters. Type again F4 to exit the menu. The required values for parameters are:
-
BAUD
RATE:
19200
- DATA BITS: 8
-
PARITY:
NONE
- STOP BITS: 1
