Availability
CPUs with the "PtP" name suffix have at least one PtP interface.
Properties
Using the PtP interface of your CPU, you can connect external devices with serial interface.
You can operate such a system at transmission rates up to 19.2 kbps in full duplex mode
(RS 422), and up to 38.4 kbps in half duplex mode (RS 485).
Transmission rate
• Half duplex: 38.4 kbps
• Full duplex: 19.2 kbps
Drivers
PtP communication drivers installed in those CPUs:
• ASCII drivers
• 3964(R) Protocol
• RK 512 (CPU 314C-2 PtP only)
Devices capable of PtP communication
Devices equipped with a serial port, for example, barcode readers, printers, etc.
