INSTALLATION

Perform the following steps to connect the converter to your network and your

RS-232/RS-485 device.

1. Place the Converter near the device you want to control.

2. Using the included 9-pin RS-232 cable, plug one end into the RS-232 port on your

device, then plug the other end into the RS-232 port on the Converter.

3. If you intend to use a wired connection to the Converter, plug one end of the

included Ethernet cable into the LAN port on the Converter, then plug the other end

into an available LAN port on your router.

Alternatively, if you intend to use a Wi-Fi® connection to the Converter, attach the

included Wi-Fi antenna to the Antenna connector on the Converter.

4. Plug one end of the included AC power adapter into the Power connector on the

Converter, then plug the adapter into a nearby AC power outlet.

5. Depending on whether you are using a wired or wireless connection, perform the

steps in one of the following sections to connect to the Converter using your web

browser.

Wired

1. Open a web browser and connect to your router using the instructions found in your

router's user's manual.

2. In the router's user interface, check the DHCP client to determine the IP address of

the Converter.

3. Enter the IP address into the address bar on your browser and hit ENTER to access

the Converter's Web GUI Login screen.

Wireless

1. Create a wireless connection to the converter using the following Wi-Fi® settings:

SSID: HLINK

Password: 12345678

2. Once you are connected, open a web browser, type 192.168.16.254 into the address

bar, and hit ENTER to access the Converter's Web GUI Login screen.

Wi-Fi® connection and login parameters.

You can change the NetMode setting, but we recommend leaving it at Default.

System Settings

Click HLK-RM04 > Serial2Net UART 2 Settings to get this screen, which allows you to change

many network connection settings. The parameters in the Current column reflect the current

settings, while those in the Updated column are the new settings. Make changes, as desired,

then click the Apply button to save your changes.

Following are details about the entries.

•Serial Configure: Sets the serial communications parameters. The values are Baud

Rate, Data Bits, Parity, and Stop Bits, separated by commas.

•Serial Framing Length: Sets the Serial Framing Length, which is 64 by default and

usually remains unchanged.

•Serial Framing Timeout: Sets the amount of time (in milliseconds) for the Serial

Framing Timeout, which is 10 by default and usually remains unchanged.

•Network Mode: Select Client, Server, or None.

•Remote Server Domain/IP: Sets the IP address of the Remote Server Domain. This can

only be changed if the Network Mode is Client.

•Locale/Remote Port Number: Sets the port number. This can only be changed if the

Network Mode is Client or Server. When Network Mode is set to Client, this specifies

the port number of the remote server. When Network Mode is set to Server, this

specifies the local port number.

•Network Protocol: Select TCP, UDP, or None. For most configurations, set it to TCP.

•Network Timeout: Sets the amount of time (in seconds) of no data transmission

before the server disconnects. Set it to 0to never disconnect.
