Low Profile PCI card 1x RS232/RS422/RS485, #13610
Function
The W&T PC card model 13610 provides on port 1 a switchable
serial RS232/RS422/RS485 interface with 1kV DC galvanic iso-
lation. Ports 2 through 4 can also be used for any three non-
galvanically isolated serial interfaces.
Wiring configuration
The serial connection of the Low Profile PCI card is configured
as a DB9 plug. The connector pin assignments are shown in
the following table:
RS232 mode
RS422/RS485 mode
Modes
The combined RS232/RS422/485 interface of the PCI card can
be set to various operating modes using the DIL switches loca-
ted near the serial connector as described briefly below:
RS232 mode
This mode provides one data channel each (RxD and TxD) in
each direction as well as six handshake channels (RTS, CTS,
DSR, DCD, DTR and RI).
