Assignment Of The Internal Ports On The Motherboard - Siemens SIMATIC Box PC 620 Manual

Internal Serial Port COM2 (V.24)
This port is connected in parallel to the external COM2 port. Both ports can
therefore only be used alternatively. The assignment is executed in such a way
that a 1:1 connection to a 9 pin subminiature Cannon socket can be made when
using insulation piercing connecting devices. The maximum cable length is 100cm
with a data transfer rate of 9.6 Kbps.
