Product Features
The FlexOM Gateway V2 is an IoT cloud-based gateway that allows the integration of
various hardware and system scenarios
Connect multiple CPS inverters and other devices to a single RS485 daisy chain
RS485 pass-thru allows third-party controller to act as a client in parallel with the FlexOM
Gateway V2
Enables diagnosis of RS485 wiring issues through the CPS FlexOM portal
Modbus TCP pass-thru (Third-party controllers can read/write commands to CPS inverters
through Modbus TCP.)
Easy mass deployment and configuration via the CPS Connect Pro app using built-in BLE
Reduces the need for truck rolls via remote firmware updates

Caution:
If the length of either the cable connecting to the RS485 port or the AUX port
of the gateway is over 1000 meters, the switch for the 120 ohm terminating
resistor corresponding to the port must be set to ON.
Power Switch
POWER ON
Caution:
Before configuring the gateway,
ensure the power switch is set to ON.

Note:
Confirm the gateway model by checking the model number and SN listed on the label on top of the
gateway card.
The FlexOM Gateway V2 cards must have an Internet connection to enable remote data
communications via the CPS Portal.
The standard FlexOM Gateway V2 requires an Internet connection via the Ethernet port.
The FlexOM-4G Gateway V2 includes a pre-installed SIM card and 5-year 4G cellular plan.
The FlexOM-4G Gateway V2 may not use, be configued with, or be activated with a third-party
SIM card.

The FlexOM Gateway V2 requires a connection to the Internet using Ethernet. Any LAN
firewall ports must be opened before commissioning the FlexOM Gateway V2.
The following ports must be opened both ways (for incoming and outgoing
communications):
TCP 1884 with destination IP 47.254.52.209

Internet Interface: Ethernet (FlexOM Gateway V2)
Internet Interface: 4G (FlexOM-4G Gateway V2 only)
The FlexOM-4G Gateway V2 includes a pre-installed SIM card and is compatible with
AT&T, T-mobile, and Verizon networks. The standard 4G cellular data plan period is 5
years.
Once the FlexOM-4G Gateway V2 is powered on and the 4G antenna has been installed
(see page 26), it will automatically select and connect to the provider network with the
strongest or most stable signal.
