Page 12: Jumper Settings
___________________________________________________________________________________ 2.3 Jumper Settings For RS-422/485 serial communications, when an electrical signal travels through two different resistance junctions in a transmission line, the impedance mismatch will sometimes cause signal reflection. Signal reflection causes signal distortion, which in turn will contribute communication errors. The solution to this problem is to establish the same impedance at the end of the lines by terminating them with resistors. - Page 13 D + (Tx+) D – (TX-) D – SUNIX M.2 PCI Express RS-422/485 Serial board equips independent TX and RX termination resistors for each serial COM port. User can modify the dip switch setting to avoid impedance mismatched problem when operate under Multi-drop transmission.

- Page 31 ___________________________________________________________________________________ RS-485 ACS™ Technology (Default: Enable) Auto Carrier Sense (ACS™) technology is the data flow control under RS-485 half duplex (one-way traffic) communicating. It manages data flow between computers or devices or between nodes in a RS-485 network, so that the data can be handled at an efficient pace Auto Carrier Sense (ACS™) technology will check the status of RS-485 communication bus.
- Page 32 RS-485 AHDC™ Technology Since RS-485 is bidirectional which means the driver is turned on only when it needs to transmit some data, otherwise it is in floating mode. SUNIX developed a new design to control the direction of driver (On or Off) automatically which is called Auto Hardware Direction Control/Carrier Sense.

Page 34: Troubleshooting
___________________________________________________________________________________ 5.1 Troubleshooting 1. System fails to find the PCI Express serial board or COM port. A: It may cause by following issue: a. The board is not properly plugged into the PCI Express slot. b. Please clean the golden finger. c. - Page 35 ___________________________________________________________________________________ before enabling the hardware flow control function. 5. How large FIFO length I should set? A: FIFO (First-In-First-Out) buffers are used to reduce the frequency of interrupt processes for UART chips. The size of the buffer will determine the number of times the cards need to interrupt the computer’s CPU in order to process a string of data.
