About the RS-232 cable
We recommend buying an off-the-shelf "null modem"
RS-232 cable. It will work with the
COBAS INTEGRA 400 plus analyzer or the
Cedex Bio HT Analyzer.
The correct pin assignment is defined in the ISO 2110
standard for 25-pole connectors and in the ISO 4902
standard for 9-pole connectors.
