Setting Port Parameters
The Port tab of the Options menu (see Figure 9) involves options which regulate parameters of the
serial port through which the console communicates data with the PC in cases of finding devices as
well as reading console configuration from or writing it to the console memory.
Figure 9. Options Window: Port Tab
These options are to be varied when some problems with the communication line or communicating
data have been occurred. (For example, the PProg cannot find the console or the Console Status
Indicator shows failures, see PProg Operating).
The Number of Stop Bits parameter is advisable to be set to 2.
The Receive / Transmit Switching parameter defines the way of receiving/transmitting data at the port
(automatically or software supported) depending on the way the console is connected to the computer. If the console is connected:
9
To a RS232 port of the computer via the console's RS232 port, or
9
To a RS232 port of the computer via the console's RS485 port and an S2000-PI interface converter, or
9
To a USB port of the computer via the console's RS485 port and a relevant interface converter,
the "S2000/S2000-PI" value is recommended to be selected.
If, otherwise, the console is connected to a RS232 port of the computer via the console's RS485 port
and a PI-GR interface converter, the "PI/PI-GR" value should be set.
If the console is not recognized by the PProg during program operating, you can try to fix the problem
by selecting another value of the Receive / Transmit Switching parameter.
