Logicmaster 90-30 V9.05 Software Download May 2026

To connect to a Series 90-30 CPU (e.g., IC693CPU331):

Even with a legitimate installation, you may encounter these problems:

| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | “Dongle not found” | Parallel port emulation fails in VM | Use a physical PC with a real parallel port, or switch to a serial dongle. | | “Out of conventional memory” | TSRs (terminate-stay-resident) loaded | Create a clean DOS boot floppy or VM without AUTOEXEC.BAT drivers. | | “Cannot open COM port” | USB adapter driver issues | Use an FTDI-based USB-to-serial adapter. Assign COM1 within Windows. | | “Timed out communicating” | Wrong baud rate or parity | Check PLC dip switches. Default is 19.2k, but many plants use 9600. | | “Project checksum error” | Corrupt file from bad media | Re-copy project from backup. Do not use floppy disks older than 10 years. |
