- Page 2 Modbus gateways used to simply forward Modbus RTU requests and responses to Modbus TCP, and vice versa. Most Control Solutions gateways involve mapping, and the gateway itself contains registers or objects which hold copies of data found in other devices. This intermediate data buffering is what allows access to the same data from multiple protocols.

Page 3: Important Safety Notice
By using ANY Control Solutions, Inc., product, the user has agreed to assume all risk and responsibility for proper system design as well as any consequence for improper system design. - Page 4 2. Connecting the Gateway for the First Time file:///C:/AAA_CSI/Literature/2015 User Guides/BB2-6010-GW User G... Follow these steps to make the initial connection to the BB2-6010-GW. (a) Connect power. Babel Buster BB2-6010-GW: Apply +12 to +24VDC or 24VAC to the terminal marked “POWER”, and common or ground the the terminal marked “GND”.
- Page 5 2. Connecting the Gateway for the First Time file:///C:/AAA_CSI/Literature/2015 User Guides/BB2-6010-GW User G... (b) Connect a CAT5 cable between the RJ-45 jack on the gateway, and your network switch or hub. You cannot connect directly to your PC unless you use a “crossover” cable. (c) Apply power.
- Page 6 2. Connecting the Gateway for the First Time file:///C:/AAA_CSI/Literature/2015 User Guides/BB2-6010-GW User G... (e) Open your browser, and enter “http://10.0.0.101/” in the address window. You should see a page with the “Babel Buster BB2-6010” header shown above (or as applicable by model). From this point, you will find help on each page in the web site contained within the product.

(h) Most changes are stored in an XML configuration file in the device’s Flash file system. Only a few are stored differently, and the IP address is one of those. Normally, clicking Update on any configuration page only stores that configuration information to a temporary RAM copy of the configuration file.
- Page 8 3. Configuring Gateway as a Modbus RTU Master file:///C:/AAA_CSI/Literature/2015 User Guides/BB2-6010-GW User G... The gateway is configured based on which side is Modbus master. If your Modbus TCP master wants to get data from Modbus RTU slaves, then configure the gateway with Modbus TCP as master. If your Modbus RTU master wants to get data from Modbus TCP slaves, then configure the gateway with Modbus RTU as master.
- Page 9 3. Configuring Gateway as a Modbus RTU Master file:///C:/AAA_CSI/Literature/2015 User Guides/BB2-6010-GW User G... Select baud rate and parity from the drop down list. Click either Master or Slave buttons to select type of operation. Enter timing parameters or address as applicable. Click update to register your changes. IMPORTANT: Set timeout to something long enough for the device(s).
- Page 10 3. Configuring Gateway as a Modbus RTU Master file:///C:/AAA_CSI/Literature/2015 User Guides/BB2-6010-GW User G... When Modbus RTU is master, you need to tell this gateway what IP address is mapped to which RTU slave address. If there is a one to one correlation between RTU slave address and Modbus TCP address, enter them as illustrated below.
- Page 11 3. Configuring Gateway as a Modbus RTU Master file:///C:/AAA_CSI/Literature/2015 User Guides/BB2-6010-GW User G... There are instances where a Modbus TCP device contains several unit numbers at the same IP address. This is common in a multi-channel device where unit specifies channel number. Since RTU does not have the luxury of this sort of multi-layer addressing, your RTU master will need a way of seeing each channel as a separate RTU slave address.

A. Hardware Details file:///C:/AAA_CSI/Literature/2021 User Guides/Errata Updates/BB2-6... Appendix A Hardware Details Wiring Wiring for the Babel Buster BB2-6010 is illustrated below. Wiring for the Babel Buster SPX is illustrated below (see section A.4 for SP). 1 of 6 4/8/2021, 8:54 AM... - Page 15 A. Hardware Details file:///C:/AAA_CSI/Literature/2021 User Guides/Errata Updates/BB2-6... Wire the gateway as illustrated. Follow all conventional standards for wiring of EIA-485 networks when connecting the Modbus RTU EIA-485 (RS485) network. This includes use and termination of shield, termination of the network, and grounding. IMPORTANT: Although EIA-485 (RS485) is thought of as a 2-wire network, you MUST include a third conductor connected to GND or common at each device so that all devices are operating at close to the same ground potential.
- Page 16 A. Hardware Details file:///C:/AAA_CSI/Literature/2021 User Guides/Errata Updates/BB2-6... Babel Buster BB2-6010 and SPX request/reply LEDs reflect RTU traffic while the Ethernet activity LED will indicate TCP traffic. To see TCP errors, one needs to look at the Errors page in the web UI. Babel Buster SP: Since there is only one LED available, it simply indicates Modbus traffic.
- Page 17 A. Hardware Details file:///C:/AAA_CSI/Literature/2021 User Guides/Errata Updates/BB2-6... Operating as Modbus Slave, flashes if an exception code is sent (meaning the received request resulted in an error). Ethernet link LED is the yellow LED integrated into the CAT5 connector on BB2-6010 and SPX, and green on SP.
- Page 18 A. Hardware Details file:///C:/AAA_CSI/Literature/2021 User Guides/Errata Updates/BB2-6... The "Init" jumper on the server module should only be used when advised by tech support. Installing this jumper prior to power-up causes the server to go into firmware update mode. Babel Buster SP DB-9 Connector & DIP Switch Pin connections are shown below.
- Page 19 A. Hardware Details file:///C:/AAA_CSI/Literature/2021 User Guides/Errata Updates/BB2-6... In addition to connecting wiring as indicated above, you need to change the DIP switch settings to select what type of port you are configuring. 6 of 6 4/8/2021, 8:54 AM...
