The PC-link allows data to be exchanged between the PC and the temperature converter or other interface module. The PC-link is ATEX certified, which allows the configuration of the module while remaining part of the hazardous area circuit.
The PCL45USB device is powered from a computer USB port and is ready for communication immediately after the physical connection has been established.
The PCL45 legacy device is powered from the RS232 connection and from the interface module data lines. The serial port on a computer must be able to supply ± 8V @ 3mA. A minimum connection time of 15 seconds has to be allowed before data can be exchanged between the PC and the module.
Thus:
