1. Web Management
Before configuring your Case Communications 3611, please make sure your PC has
installed the correct software as shown below
The lowest requirements of user PC is as follows:
▪Installation operation system (as Windows 10 / 8 / XP/2000, Windows 7etc)
▪Installation Ethernet card
▪Install Browser explorer (IE6.0 or higher version etc)
▪Install and startup TCP/IP protocol
1.1 Network settings
The 3611’s default IP address: 192.168.1.254, subnet mask: 255.255.255.0.
When accessing the 3611 server through the WEB browser. The IP address of the serial device
server and PC must be in the same Local Area network. You can modify PC’s or serial device
server’s IP address to make sure that they are in the same Local Area Network.
Follow the steps below
Modifying your PC’s IP address.
Step 1 Click Start->Control panel->network
connections->Local area Connection->Properties-
>Internet protocol(TCP/IP)Setting PC’s IP address: 192.168.1.X (X is expect 254, from 2 to
253).
Step 2 Click “OK”, IP address modified successful. Configure your IP Address in Windows as shown
below.:

1.3.2. Network Information
The 3611 supports 2 modes of operation for IP Addressing. DHCP and static IP address.
When using the DHCP function, the IP address of the device can be obtained from a DHCP Server.
If you need to connect to the Domain Name System, please fill in the Gateway and DNS address. As
shown below
IP Address
The IP address is a 32 bits length address. The device that connects to the Internet, IP address has
2 options configured:
•net-id
•host-id, IP address can set in static IP or DHCP.
Subnet Mask
The Subnet Mask is an IP address with32 bit number, that divides the IP address into 2 parts:
Subnet addresses and host computer addresses.
Default Gateway
The default gateway in the Host computer is usually called the ‘Default Route’. The Default
Route is the route chosen by the network when the destination address of IP packets is on a
different network. All packets not on the local subnet will use the default route.
DNS Address
The DNS is the Domain Name Server. It resolves the name of a destination to an IP address
internet can identify. If the 3611 needs to visit some Host devices, it needs to use the DNS server
to resolve an IP address.
Notice
If we need the 3611 to “automatically obtain an IP address”, please ensure the
DHCP Server is in the same network and can obtain an IP address. After
“automatically obtaining an IP address”, the 3611 needs to use the software
manager to search the device and obtain the IP address for the device.

Logon to the serial server’s Web interface, click [Serial Setting], choose the required
configuration in the corresponding drop-down menu.
Serial settings Web interface as shown below. When the serial server communicates with the
serial interface device, serial server’s setting is as follows:

These configuration options are explained below,
COM Mode: RS-232 full duplex/RS-422 full duplex/RS-485 half duplex
Baud rate: It is a parameter to check the communication speed. It shows to transfer how many
bits in 1 second. For example, 300 baud rate means have 300 bits transferred in 1 second.
Parity bits: It is a simple method to checkout fault in serial communication, have 4 types:
Even, Odd, Mark, Space
Data bits: It is a parameter to check the actual data bits in communication. The standard is 5,
6, 7, 8.
Stop bits: The last bit of the single Packet, Typical bit is 1, 1.5 and 2. Serial device server’s
stop bit is 1, 2.
Max frames: The frame length that serial interface data convert into Ethernet data, within the
range of setting time, it forwards when data is equal to or longer than the setting frames.
Available setting value ranged from1 to 1460.
Character Delay: The wait time when serial interface send data do not 1 data frames. If up to
this time and do not have data, then send automatic.
CtrlBreak default output time: Setting CtrlBreak default output time
