The existing COM ports are determined as the communication interface when starting the program and selecting
RS232/RS485. Only COM ports found are available for
selection.
The COM port of an external RS232 or RS485 converter
may be determined (and, if required, changed) via the
Windows system control.
Example for Windows XP: System control => System
Limiting the range of possible device addresses speeds
up the search of connected devices considerably.
Example: If only 2 devices are connected, it makes sense
to select the address range from 1 to 2.
All settings are stored as the program is terminated. If the
COM port is not available upon the next start of the program (e.g. because the converter has not been plugged in)
another valid interface is set.
To determine which COM port has been allocated to
the RS485 converter (if required), please proceed as
follows:
This example shows the COM ports of a PCMCIA card
and a USB-RS232 converter:
- Silicom Serial Card: COM1
- USB-RS232 adapter: COM4
If you use the Camille Bauer USB-RS485 converter
(Article Number 163189), the same is to be connected as
follows:
