Page 7: Hardware Configuration
Clock Modes The COMM+8.422.PCIe derives a 62.5MHz clock from the PCI express link which is divided by a 8 bit clock prescaler and a 16 bit clock divisor to provide a wide range of possible baud rates. Note that there are many combinations that can give the same result (e.g. - Page 8 Electrical Interface Selection Each of the eight ports on the COMM+8.422.PCIe can be individually configured as an RS-422, or RS-485 interface. This is selectable via the port DIP-switch, each is labeled with its port number. Switch 1 (Silk M1) Switch 2 (Silk M0)

Page 12: Technical Description
Technical Description The COMM+8.422.PCIe provides eight RS-422/485 ports from a single PCIe slot. The COMM+8.422.PCIe utilizes the OXPCIe954 UART. This chip features programmable baud rates, data format, interrupt control and industry leading 128-byte transmit and receive FIFOs. The UARTs are register compatible with 16C450, 16C550, 16C654 and 16C750 UARTs. The FIFO depth can be changed to match the depth of these UARTs. - Page 13 The RTS output is only available in RS-422 mode. The RTS output is tri-stated in RS-485 mode and therefore unusable. The CTS input is available in all modes. © Sealevel Systems, Inc. 7802e Manual | SL9249 11/2022...
