Introduction Introduction This operating manual serves as the primary document for familiarising users with the parameters of the radio modem, its properties, modifications, and with the parameters of connecting parts. In order to master all the functions of the radio modem and the MORSE system you should refer to other documents.
Radio modem RE400 1. Radio modem RE400 RE400 is a transparent radio modem for wireless data transfer with a modern, digital solution of the radio part (Software Defined Radio). It provides a wide tuning range including software-configurable channel spacing. It is equipped with Ethernet and RS232 interfaces, Powered over Ethernet (PoE) or via pins on a serial interface connector. Configuration is performed via an ordinary Internet browser.
Description 2. Description 2.1. Compatibility Firmware version 2.1.x.x is not compatible with older versions 2.0.x.x. Older fw needs to be upgraded with the new version 2.1.x.x, see Section 2.7, “Firmware upgrade”. 2.2. Operation modes There are 3 possible operation modes: • Main mode – mode of a standard operation • Service mode – mode for firmware download • Bootloader mode – mode for downloading bootloader 2.2.1.
Description Communication over an Ethernet bridge The data received on ETH channel are sent immediately to RFC. The packet received during RF transmitting is discarded. The operating with the Repeater when the parameter NoR has a nonzero value is a exception. The input buffer of depth 1 packet is used here. It allows accept the response from ETH device connected in the short time after receiving the packet from RFC. The RFC transmitting is suspended at that time, see the article Repeated packets.
Description Compression There is built in compression on the RF channel. Its final efficiency depends on the data structure, of course. Fragmentation It is possible to set a threshold on the radio channel from which transmitted packets begin to fragment. The receiving modem transmits a packet to the interface only when all fragments are received successfully. This also applies in a Repeater for transmission of a packet to the RF channel. From fw 2.1.3.
Description 2.3. First start of radio modem 1. Two radiomodems having the same address must not be in the common network neither radio nor ethernet. Parameters of each radio modem are set during production with default values : IP address 192.168.1.2, mask 255.255.255.0. It is strictly forbidden to connect a radio modem to LAN before setting up the appropriate IP address and mask.
Description 2.4. Radio modem configuration ON LINE The radio modem is connected to your PC as described in Section 2.3, “First start of radio modem” and its parameters can now be set: Fig. 2.1: Settings menu Product Diagnostics Radio 12 • identification data can’t be changed: • Type: RE410 — specific type for specific frequency range, see Section 5.2, “Labelling of Radio Modems” • Product No.: 7347743 — unique production number (it is used for a Ping test, for example) • FW version: 2.1.7.
Description • Fragment threshold— the threshold, from which the packet fragmentation in RFC starts exert (50 - 1480 bytes). See Section 2.2.1, “Main mode” • Repeater — repeated transmitting, store and forward transmitting.
Description TX_FREQ=402125000 RX_FREQ=402125000 SPACING=1 RFPWR=0 REPEAT=0 REPEAT_NO=0 SBITS=2 IDLE=10 SIZE=4000 HANDSHAKE=0 FRS=1480 Note: Check whether the set frequency is within the range for the specific type of modem; it doesn't work for off line configuration. 2.5. Diagnostics Fig. 2.2: Diagnostics menu Pings are used for testing response times and signal strengths from remote radio modems. • Ping address: 7353743 — product No.
Description • Stop — stops transmitting • Refresh log — updates the Ping activity log • Ping activity log — standard information + RSS (received signal strength). The message rss NA (> -73dBm) is caused by signals stronger than -73dBm. There are separate records for transmitted and received pings. 2.6. Error log When the radio modem is in operation packet processing messages are generated: Fig. 2.
Description The serial number of the fragment does not correspond to that expected. • Fragment - total number error Information about the total number of fragments does not correspond to the previous fragment. • Fragment - source address error The received fragment is from another source address (serial number of radio modem) than the previous fragment.
Description 2.7. Firmware upgrade There is fully functional firmware in the radio modem from production. When a firmware upgrade is required, take the following steps (example for fw version 2.1.7.0). It is necessary to use user account with administrator privileges. Remember switch off the firewall in the PC. Install application trloader to your PC a. 1 Download installation package , e.g.: 2.1.7.0/trloader-win-gui-0.1.3.0.exe here: www.racom.eu/Download/Archive/ECONOMY radio modems/ b.

Connectors 3. Connectors 3.1. Antenna There is an SMA-jack antenna connector on the radio modem panel. Use only the respective type of connector of the respective impedance on your antenna cable : SMA-plug, 50 Ω. It is recommended to use antenna coaxial cables like this: RG58 up to 10m, RG213 up to 25m, H1000 for longer. Fig. 3.1: Antenna connector SMA Important A radio modem may be destroyed if an antenna or dummy load antenna is not connected. 3.2. Serial interface Tab. 3.

Radio modem installation 6. Radio modem installation 6.1. General description Racom radio modems feature robust, metallic casing. They are used in different applications in different environments, ranging from air-conditioned offices to heavy-industry plants. Information in this chapter describes the standard method of installation, used in common industry applications. It is based on regulatory standards which apply to the equipment and on the long-term experience of our engineers.
Radio modem installation 6.3. Supplying power to the equipment A power supply has to meet technical specifications of the equipment powered, see Section 4 Table of Technical parameters. Radio modem can be powered either over the Ethernet interface according to the PoE (Power over Ethernet) standard or over the SCC (RS232) interface by DC voltage 10.8-30V (13.8V nominal). When powering over SCC we recommend one of the MORSE power supplies, e.g.

Appendix Appendix A. Appendix Setting IP addresses in your PC It is necessary to set the respective IP address in your PC for radio modem configuration, e.g. 192.168.1.233. It is supposed your PC is using DHCP as a primary configuration • Open menu Start, Settings, Network connections, Local Area Connection • When window Local Area Connection Status is opened, click Properties • Next window is opened.
Appendix • The next window is opened • Select General (recomended) and choose Use the following IP address • Insert IP address 192.168.1.233 • Set Subnet mask to 255.255.255.0 • Confirm OK in this window and in the previous also • • The automatic choice is a second possibility. Then the General uses e.g. DHCP server setting and the Alternate the IP address 192.168.1.233. This works more slowly and not quite reliably.
Appendix • Confirm OK in this window and in the previous also When you are not using Windows XP follow the instructions in your manual for setting the IP address. IP address check in PC While using Windows, proceed e.g. like this: 1. Click menu Start, Run… 2. Write the command cmd 3. Write ipconfig and read the IP address in PC and the mask: Check the connection PC - radiomodem using Ping While using Windows, Ping is executed like this: 1.
Appendix 4. Write ping 192.168.1.2 and press OK 5. A window will appear with a message: When communication doesn’t work properly you will get a Timeout expired message. If the communication between web browser and radiomodem does not work although, check the browser setting. In the menu File there is the item Work offline which must not be marked off. © RACOM s.r.o.
