Modbus TCP, EtherNet/IP, BACnet IP and others. The RS422/485 side can connect to serial devices over long distances (up to 4,000 ft.). The GRID485 supports RS485 in 2-wire mode (half-duplex) or in 4-wire mode (full-duplex). The half-duplex or full-duplex operation is chosen in the device configuration.

120 Ohm resistors from the transmit and receive lines. Ethernet Connection The GRID485 has an RJ45 Ethernet connector that supports 10/100 Mbps Ethernet. There are 2 status LEDs for indicating the status of the network connection. The following table describes the LED functionality for the wired Ethernet connection...
Wire power to the GRID485 using the GND and 8-24VDC terminals. The GRID485 can use a DC power source from 8-24VDC. The current draw is determined by network activity and serial port communications. In general, a 2.5W supply will handle the load.
RS485 Connections The GRID485 has jumper terminals for adding a 120 Ohm termination resistor to the TX/485 and to the RX lines. Add these jumpers ONLY if you have long transmission lines and termination resistors are needed. Termination should be made only at the ends of the RS485 bus.
RX+ and RX- terminals. Make sure to match polarities when wiring to other RS422/485 devices. The TX pair of the GRID485 should be wired to the RX pair of the other devices. The RX pair of the GRID485 can be wired to the TX pair of multiple RS485 devices or only one RS422 device.
DHCP server. Finding the device on the network 1. Run the Grid Connect Device Manager software on a PC to find the GRID485 device on the network and determine its IP address which was assigned by your network’s DHCP server.
By default, the Soft AP mode is enabled with a SSID of GRID45ppp_xxxxxx, where ppp is a protocol designation and xxxxxx are the last six hex digits of the unique GRID485 MAC address. An SSID of GRID45MB_xxxxxx is used when Modbus TCP firmware is loaded. The serial number is derived from the module’s base MAC address which is provided on the MAC address label on the module.

Access Web configuration by opening a web browser and navigate to the IP address 192.168.4.1. Continue to the GRID485 Web Configuration section below. GRID485™ Hardware User Guide...
GRID485 WEB CONFIGURATION Web Manager Entry After navigating the browser to the GRID485’s web interface you should have the following prompt: By default you should leave the User Name and the Password blank. Click “Sign in” to access the Web configuration pages.
Note that the Wi-Fi Interface shows it is Enabled but not connected. Go to the Wi-Fi Configuration section and follow the steps to configure this interface. If you do not intend to use the Wi-Fi interface of the GRID485 then you should disable the Wi-Fi interface.
To communicate with the GRID485 device on your local Wi-fi network you will need to configure the wireless network interface. If you do not intend to use the Wi-Fi interface of the GRID485 then you should set the State to Disable Wi-Fi.

Parity: choose between Disable, Even and Odd parity. Stop Bits: choose between 1, 1.5 and 2 stop bits Flow Control: choose from the following options… RS485 control, Half-duplex – for RS485 2-wire half-duplex RS485 control, Full-duplex – for RS485 4-wire full-duplex GRID485™ Hardware User Guide...
Administrative Configuration The GRID485 module has an Administrative page for setting service options and updating firmware as well as factory reset, saving and restoring configuration settings. Select and click on the Administrative menu option (left side). Web/telnet user: sets the user name for configuration access via web manager and telnet.
The module will upload and store the new firmware. The upload may take around 30 seconds and may not display a progress indicator. After a successful upload the module will display a success screen and reset. GRID485™ Hardware User Guide...
OPERATION Asynchronous Serial The GRID485 device supports asynchronous serial communication. This serial communication does not require a transmitted clock signal (asynchronous). Data is transmitted one byte or character at a time. Each transmitted byte consists of a start bit, 5 to 8 data bits, optional parity bit and 1 to 2 stop bits. Each bit is transmitted at the configured baud rate or data rate (eg 9600 baud).
