PQTSoft Remote in brief
PQTSoft Remote has been conceived to program PQT-90
by means of a data transmission from the PC to the instru-
ment via RS232 or RS485 serial interface. The choice
between one interface or the other is therefore very impor-
tant for the correct operation of the instrument as shown
by the following figure:
Local single PQT connected to
the PC by RS232 serial port
Maximum 255 PQT’s in an RS485 local network connected
to the PC by RS232 thanks to the RS485-RS232 SIU-PC
converter.
Maximum 100 remote single PQT’s connected to the PC by
means of a telephone network thanks to an analogue/GSM
modem.
Maximum 25000 PQT’s in max 100 remote RS485 networks
connected to the PC by means of a telephone network and
RS485-RS232 SIU-PC.
