DOCUMENT NUMBER 8DAJ000001 Sept 2020 Copyright © 2020 Hitachi ABB Power Grids. All rights reserved TRO620 Quick Start Guide 1. Quick Start The following section describes the procedure for setting up the TRO620. a. Connect and power up the router. Connect the DC power (7 – 32 VDC) with the appropriate power supply. The ‘Power’ LED should indicate that the router is now receiving power. b. Insert a cellular SIM into the SIM slot 1 located at the back of the router. A second SIM can also be inserted into the second SIM slot 2. 2. Setup a computer to access the Tropos Configuration Utility a. Connect an Ethernet (RJ45) cable from a laptop’s Ethernet interface to Ethernet Port 1 on the router. The LAN interface on the laptop should be configured with the following IP address and subnet mask: IP address: 192.168.167.160; Subnet Mask: 255.255.255.0 b. Open a browser (IE, Chrome, or Safari) and type in the following URL to access the TRO620’s Web interface: https://192.168.167.166 c. At the login prompt, type in the super-user username and default password. Upon initial login, the super-user password must be changed immediately. TRO620 super-user: Username: admin Password: tropos d. Navigate to the Cellular configuration page. Select the SIM slot to activate and configure the appropriate APNs for the respective SIM card. Confirm that the cellular interface has received an IP address from the cellular net- work and the appropriate LEDs are lit. Refer to the Router LEDs section in the Functions Guide. e. Once the cellular interface has been assigned an IP address, verify network connectivity to a well-known Internet address such as 8.8.8.8 or to a corporate IP address that is known to be reachable from the TRO620 router. f. In the case of a dual SIM configuration, where both SIM slots have a SIM inserted, check the IP address assign- ment, APN configuration, and connectivity for each SIM to establish that they are operating correctly and can acquire an IP address. g. Once the IP address is assigned and connectivity has been established, proceed with additional router configura- tion as required. 3.

HITACHI ABB POWER GRIDS ABB Enterprise Software Inc. 3055 Orchard Drive, 95134 San Jose, US Modular Approval Letter 2020-11-05 FEDERAL COMMUNICATIONS COMMISSIONS Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 Subject: Modular Approval Letter The Device, FCC ID: P9J-NEPTUNE24, is seeking FCC authorization as a modular transmitter. The EUT meets the requirement for modular approval as detailed in FCC Public Notice DA 00-1407. Compliance to each of the requirements is described below: Item Requirements EUT 1 The modular transmitter must have its own RF shield- ing. Device is equipped with Metal shielding to cover RF section. Refer to external photos 2 The modular transmitter must have buffered modula- tion/data inputs. All inputs to the modules are buffered through logic or mi- croprocessor inputs. 3 The modular transmitter must have its own power sup- ply regulator Internal power regulator. Re- fer to Block diagram 4 The modular transmitter must comply with the antenna requirement of section 15.203 and 15.204(c) Device is equipped with unique antenna connector. Refer to external photos 5 The modular transmitter must be tested in a stand- alone configuration i.e., the antenna, AC or DC power and data input/output lines must be connected to the module but, the module must not be inside another case during testing Device was tested inside a host device for Limited Modular Approval. Refer to setup photos. 6 The modular transmitter must be labeled with its own FCC ID number and if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed mod- ule. Label of the module has been provided. Refer to the Theory of Operations document. 7 The modular transmitter must comply with any specific rule or operating requirements and the manufacturer must provide adequate instruction along with the mod- ule to explain any such requirements. Refer to “User’s Guide” Exhibit Error! No text of specified style in document. 2/2 The modular transmitter is manufactured so that the user cannot influence the operation of the transmitter that will operate outside of the scope of the regulations. 8 The modular transmitter must comply with any applicable RF exposure requirements. Address compliance with the Commission's RF expo- sure limits in Sections 1.1310 and 2.1093. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF exposure compli- ance in accordance with Section 15.247(b)(4). RF exposure evaluation was performed on the module inside a host device in accordance with FCC 2.1091.
