1) The interfaces, etc. available on the device or module have been numbered for the purpose of clear differentiation. This numbering may deviate from the
numbering used by the respective operating system, however.
2.3.5.1.3.2 I/O address and IRQ

1) The default I/O address and IRQ can be modified in BIOS.
2.3.5.1.3.3 RS232 - Bus length and cable type
The maximum transfer rate of 115 kbit/s depends on the cable length as well as the type of cable being used.
Extension
≤15 m
≤10 m
≤5 m
Preferably, the cable material used should have the following properties or deviate only slightly from them in order
to achieve an optimal transfer rate.
