2.2.4 Equipment start-up and Reset switch operation
HK-880 provide Reset switch, it can be used to recover plant setup manually without enter HK-880
Power start-up step on the equipment
Connect DC IN interface and 5VDC power plug, PWR red LED is bright, Ethernet LINK LED is bright, then break, after
about 10 seconds(under normal start-up), TX/RX serial interface LED are twinkle 3 times, the system have finished initializtion
process
Note; if you want to start quickly, you can set to high speed start-up
Reset operation step:
①press Reset key
②connect the HK-880 power, PWR red LED is bright
③Wait for about 10 seconds, TX/RX LED is twinkle frequently, it mean the parameter recovered to plant setup, then
break and reconnect
Chapter 3 Manager method
3.1 Equipment manager method
HK-880 series serial device server can used Web browser, Telnet and Console to collocate and maintain, it can choose
corresponding manager style according to the status
3.1.1 Web browser management
Confirm to HK-880 serial device server and net are connect normally and keep it in the same net range with the
computer what equipment you want to enter, if you don’t know the equipment IP, you can used Console control plate and
dummy serial software to search the equipment IP. Enter HK-880 IP to the Web browser then the enter interface occur as
below:
HK-880 default IP: 192.168.0.200, enter default user name: admin, and password: admin, then enter into collocation

3.2.1 Equipment collocation
Quick setup
HK-880 provide quick setup function, user can use the function to setup the serial device server step by step,
the operation is very easy despite you never used the serial device server product, use the function can collocate
HK-880 easy
Quick setup function divide into 4 steps:
Step 1: setup the IP, subnet mask, gateway and DNS server etc..
Step 2: setup the serial interface working style and speed etc..

Step 3: setup application mode, the system default mode is Real COM
Step 4: save/restart, save and release the parameter user collocated
After the 4 steps setup, serial device server can work normally, you just need install the driver on the terminal
such as computer, then it can communicate with the HK-880 serial interface through the net
Server setup
You can collocate the HK-880 equipment net parameter in the serial device server interface, they are included
equipment name, IP, subnet mask, gateway, DNS server1, DNS server2, DHCP and Ethernet work mode:

Auto is the default mode of Ethernet, user can set to 100M full/half and 10M full/half
If user need to use the HK-880 to access internet domain name, fill the main and secondary IP into the
DNS server 1 and DNS server 2 are necessary, so that can use the domain name server to explain the IP which domain
name you want to access.
Serial interface setup
Serial interface include :
Serial interface style:232/485/422
Baudrate: 110-460800bps
numeric bit data: 5~9
Stop position: 1、1.5、2
Parity check: None、Odd、Even
Flow control: None、CTS/RTS、DSR/DTR、Xon/Xoff
Inactivity Time: 5~5000 MSEL
Inactivity Time is exceed the value when HK-880 serial interface received the data, it can enclose the
data , then transmit. The system default value is 10 ms, you can set the time under 10 ms if you want
to increase the transmission, this need to according the actual status to set up.
Packing Length: 1~1024 byte
HK-880 will transmit the data packet immediately when the received data reach to value you set, the system default
value is 1024 byte.

Operation mode
Real COM
The each serial interface of the serial device server can reflect the serial interface of HK-880 to fictitious
serial interface local machine through the driver(Windows Virtual COM/Linux TTY）. Real COM collocate as
picture:
Data Socket
HK-880 serial device server provide normal Socket API net interface, user can used the Socket under
operating system which support TCP/IP to access to HK-880 server interface. TCP/UDP socket mode divide
into TCP Client, TCP server and UDP as TCP client, TCP server and UDP style
When two HK-880 product is used in pairs, you can collocate two equipment for TCP Clint and TCP
Server mode or UDP mode, The two side of HK-880 product connect RS-232/422/485 business interface,
the applied mode like this can connect two nonsynchronous terminal equipment through the IP transmission
network.
