The RxD0 and TxD0 signals are forwarded to a level converter for
the RS-232 standard. The PCAN-Router model with screw terminal
block provides access to the adjusted signals at terminals 9 (RS-232
RxD) and 10 (RS-232 TxD).
Attention!
The RxD0 (pin 1) and TxD0 (pin 2) signals in connec-
tor panel J4 are designed for TTL levels only. Using RS-232
levels at these connections can cause damage to the electronics
of the PCAN-Router.
