2.1 Hardware Installation
The hardware installation of M.2 PCI Express serial boards is simple. Before
inserting the card into the M.2 slot, please follow the detailed steps given
below to install the PCI Express serial board into your computer.
Step 1: Remove the screw attached to the motherboard.
Step 2: Insert M.2 Card tightly into the M.2 slot with 20°angle.
(SUNIX M.2 Card supports Key-M and Key-B slot)
Step 3: Push the M.2 card down to the screw hole.
Step 4: Lock screw on M.2 card that you remove from motherboard in step1.
Step 5: Connect D-Sub cable with the M.2 card header one by one.
Step 6: Secure the other end of the D-Sub cable to PC chassis by locking the hex screw.
Safety First
To avoid damaging your system and boards,
make sure your PC’s power is turned off
before installing add-on card.

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.
Ideally, the two ends of the cable will have a termination resistor connected
across the two wires. Without termination resistors, reflections of fast driver
edges can cause multiple data edges that can cause data corruption.
Termination resistors also reduce electrical noise sensitivity due to the lower
impedance, and bias resistors (120 ohms for twisted pairs) are required. The
value of each termination resistor should be equal to the cable impedance.

2-Wire RS-485 working model with termination resistor:
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. Resistors should be added near the receiving side.
Note: Termination resistor near the receiving side.
Manufacturer default jumper setting is OPEN (disable 120ohms termination
resistors across the two wires)
Please refer to the following table to enable or disable 120ohms termination
resistor for each COM (RS-422/485) port. Each COM port is controlled by a
pair of DIP Switch.
