RACOM RE400 Quick Start Manual

Quick Start - RE400

6/1/2010

1. The first start of radio modem

• Don’t connect radio modem in your LAN before settings! Default IP address of radio modem may
be already used in your network.

• Do not switch on more than one radio with default settings at any one time! Only switch on the next
one after setting and storing IP parameters in the first one.

• Interconnect ETH connector of radio modem with your PC using standard cable.

• Switch on power (PoE or AUX). PWR and ETH LED have to light. After 20 sec. STATUS starts to
blink in green.

• Set IP and mask of your PC to 192.168.1.233, mask 255.255.255.0 (check user manual).

• Start www browser on address 192.168.1.2.

• Set radio modem configuration and Save it.

• Select a unique IP address of each radio modem within the network.

• When IP address is changed, conection with radio modem is lost. Next communication is possible
after change of IP address in www browser, possibly in your PC.

• Connect application to radio modem via ETH or SCC.

• Communication is indicated by LEDs (see manual).

• Before configuring the next radio delete table Art (Start, Run, arp -d) in the PC.

2. Connectors

2.1. Antenna

Fig. 1: Antenna connector SMA

There is a SMA-jack antenna connector on panel of radio modem.
On your antenna cable use only respective type of connector of
respective impedance: SMA-plug, 50 Ω. It is recommended to use
antenna coaxial cables like this: RG58 up to 10 m, RG213 up to
25 m, H1000 for longer.

• Radio modem may be destroyed when antenna or dummy load
antenna is not connected!

2.3. Ethernet interface

Fig. 3: RJ-45F

• Ethernet connector RJ-45 for 10BaseT and 100BaseT meets fully
standard of Power over Etrhernet IEEE802.3af.

• Radio modem recognizes standard or cross cable and adapts itself
automatically.

2.4. Power suply - possibilities

• AUX – via RS232 DSUB9 connector, using pins 5 and 9 (see Tab.1).
Voltage 10,5–30 V, nominal 13,8 V.

• PoE – via Ethernet connector RJ-45 using PoE standard IEEE802.3af. Voltage 38–57 V. Common
version of supplying:

plus to pins 4+5
minus to pins 7+8
the polarity can be inverted also

Other options with PoE adapter see the standard IEEE802.3af.

• ! Only ONE from above power possibilities can be used !

LED meanings

PWR Yellow – AUX (power via RS232)•

• Green – PoE (power via Ethernet)

TX Red - transmitting•

RX Green – RF sync•

• Yellow – there is a signal stronger then -80 dBm on radio channel

ETH Yellow – connected with 100 Mb/s speed•

• Yellow blinking – data transfer with speed of 100 Mb/s

• Green - connected with 10 Mb/s speed

• Green blinking – data transfer with speed of 10 Mb/s

232 Green – data receiving•

• Yellow – data transmitting

STATUS status of operating system•

• Green blinking with period 2 sec ON, 1 sec OFF – main mod

• Yellow blinking with period 1 sec ON, 1 sec OFF – Service mode

• Yellow blinking with period 0,2 sec ON, 0,2 sec OFF – Bootloader mode
