Section 3: System Management
3.1 Description
SW-DVI-16X16 can be managed by two different ways: RS232 or through Network (IP)
3.1.1 Control by RS232
1. Male 9-Pin D Connector:
Pin 2: RXD
(Receive)
Pin 3: TXD (Send)
Pin 5: GND
(Ground)
Other Pins: N/A
2. Baud Rate: 9600 bit/s, 8 bit, one stop bit, no parity bit
3. Protocol Format: SW-DVI-16X16 supports both the LIGUO hex protocol format (the A communication
format) and the B communication format.
4. Command:
Format of sending: 0xEB，Address，Command，Length of data，Data1，．．．，Data n，Redundancy.
0xEB Frame starting point, binary system showing：11101011.
Address： Code of the device, set before stepping off the product line, unchangeable,
all the devices of the same series have the same address.
Command： Show the commands by hexadecimal data.
Data length： The number of the bytes received or sent, only including those of from Data
1 to Data 4
Redundancy： Check whether it is right in the process of sending or receiving. It is
counted by the sending part when sending data and by the device when
send back the data. Method:
Redundancy= Address + Command + Data length + Data 1+…+Data n
If Redundancy=EBH, then Redundancy=14H;
If Redundancy has carry, ignore the carry and get Low 8 bits.
For example, EBH, 90H, 01H, 01H, F3H, 90H
Redundancy = 90H + 01H + 01H + F3H = 185H
Ignore the carry, e.g. Redundancy=85H.
3.1.2 Control by Network
1. Protocol: SW-DVI-16X16 supports the network control based on TCP/IP protocol, RJ-45 port offers
physical connect between the equipment and net. Actually, the equipment has a default IP address
that is 192.168.0.104 and the MAC address is labeled at the back of equipment. There are two
indicator lights reflect the net connecting state. The closer light shows the power is on or not. The
steady shining indicator light shows power on. The blinking light shows the net is working, the going
out light means the power does not connect. Another indicator light shining means connection of the
net port is common; otherwise the light going out is abnormal.
2. Set a new parameter of the IP address according to the existing one:
a. Make sure the net ready to work and the device connected to net;
