1.8.2 Serial Ports A and B Connector Pinout
The two serial I/O ports are available on the front panel via two 26-pin shielded connectors
which are compatible to the CPU-2CE and to the CPU-3CE.
Both channels are available via the VMEbus P2 connector, each with four signals (RXD,
TXD, RTS, CTS). Each of the two serial I/O ports are independent full-duplex channels. The
table below shows the pinout of serial ports A and B. The table is valid for both serial I/O
connectors A and B.
