BioStat: Setting up the fermentor - computer connection:
Cable: Converter (RS-232C to RS-422) and a 5 or 6-wire cable.
The connection between the BioStat fermentor and the host computer occurs through the serial port and a RS-232C to RS-422 signal converter. A cheap solution can be applied without special technical skills. The RS-422 interface is not as sensitive to interfering signals as the common RS-232C interface. Using differential interface lines with up to +/-15 V, RS-422 connections can be over 1000 metres long. See here for cable/pin assignment.
Use an external converter, not a RS-422 PCI card as this is often course to problems.
BioStat: Resolving communication problems:
First, check that the cables and converter are correctly installed/connected. Then download the TestComm program and copy it to the folder where the Fermentor Control Program is already installed. The TestComm program is continuously sending a signal to the fermentor and will display a text message whether the communication is working or not. Furthermore, a Run.log file is saved. If you need specific help or advice, please attach the Run.log file from the TestComm to your Email.
BioFlo: Setting up the fermentor - computer connection:
Cable: A 3-wire cable.
The connection between the host computer and the BioFlo fermentors occurs through the PC serial port (RS-232C) to the RS-232 port on the fermentor. In this file you can find information about setting up the cable and fermentor for the connection.
BioFlo: Resolving communication problems:
First, check that the cable is correctly installed/connected. Then download the BioFloTestComm program for BioFlo IIc, III, 2000, 3000, and 4000 and BioFlo110TestComm for BioFlo110. Copy it to the folder where the Fermentor Control Program is already installed. The BioFloTestComm program is continuously sending a signal to the fermentor and will display a text message whether the communication is working or not. Furthermore, a BioFloRun.log file is saved. If you need specific help or advice, please attach this log file from the BioFloTestComm to your Email.
