A4.2 Connecting the Multi Purpose to a PC
The Multi Purpose can be directly connected to the 9-way ‘D’ type serial port (usually
designated "COM1" or "COM2") on your PC. To comply with EMC immunity
standards, we recommend that you use the serial output cable supplied. If you do not
use the cable supplied, use a compatible 9-way ‘D Null Modem’ cable (with a
recommended maximum length of 3 m), with female-to-female connectors.
If your PC only has USB serial ports, use a commercially available 9-way ‘D’ type serial
to USB converter to connect the Multi Purpose to one of the serial ports.
WARNING
Ensure that the electrical installation of any equipment connected to the
Multi Purpose conforms with all applicable local and national electrical
safety requirements.
