FreeWave Technologies Ethernet Addendum

V204
Description:
This is an addendum to the manual for the FreeWave Modems (the
"Main Manual"). It covers details applicable specifically to using
FreeWave Ethernet modems to create an Ethernet Bridge. Please use
this addendum in conjunction with the Main Manual. The Data Port in a
FreeWave Ethernet Modem is a 10Base-T RJ45 connector, to be used
as part of an Ethernet LAN (Local Area Network).

In order to conserve the available bandwidth, the FreeWave Ethernet
Modems have a MAC address filter. Each packet received by the
Ethernet interface from the LAN is checked for the destination MAC
address against the filter table. If the address is contained in the table,
the packet is not forwarded across the radio link. If the address is
unknown, or known to be across the radio link, then the packet is
forwarded. An address is only added to the filter table after the Ethernet
interface positively determines that the MAC address in question is not
across the radio link. Each entry in the table has a lifetime of 4.5
minutes, to facilitate changing network conditions, and roaming across
networks.

Front Panel:
The modem has 2 rows of LEDs. The bottom row of LEDs is described in the Main
Manual. The top row has 7 LEDs that indicate the state of the Ethernet Interface.
The Modem has 2 ports: the Ethernet port (the Data Port) and the radio link; and it
includes 2 devices: an Ethernet Interface and a Radio Modem.

The TX and RX LEDs in the
top row show the activity
between the Ethernet Interface
and the Radio Modem.
The LEDs on the bottom row
show the status and activity of
the Radio Link.
LINK: green = the modem is connected to its LAN.
TX: green = the modem is transmitting to another modem over the radio link.
RX: green = the modem is receiving from another modem over the radio link.
LTX: green = the modem is sending data to its LAN.
LRX: green = the modem is receiving data from its LAN.
COL: red flash = the modem saw a collision on the LAN.

Setup: To program the modem, proceed as described in the Main Manual, with the following
exceptions:
•Capital U on the diagnostics port brings up the setup menu.
•You must use the diagnostic port (there's no RS232 Data Port in this modem)
•You must select the following settings.
Menu 1
This is neither the data rate of the Radio Link , nor the data rate of the Ethernet 10Base-T
connection to the LAN. This just sets the protocol internal to the Modem, between the Ethernet
Interface and the RF modem.
SET BAUD RATE
Modem Baud is 230400
(0) 230,400 Must be selected (for best throughput)
(1) 115,200

(B) MODBus RTU 0 Must be "0" (Disabled)
(C) RS232/485 0 Must be "0" (TTL)
(D) Setup Port 2 Must be "2"* (Diagnostics port used for Set-up)
(E) TurnoffDelay 0 No effect
(F) FlowControl 1 Must be "1" (CTS flow control)
Menu 0, Submenu F
Ethernet/IP Radio Setup
(0) Ethernet Mode 1 Must be set to "1"*
(1) Half/Full Duplex 0 You may select full or half
(2) Slave IP Stack 0 Set to “1” if not hooked up to a hub or switch
(3) Slave UDP Mode 0 “1” for UDP Connect Mode
(4) IP Address 255.255.255.255 Used for slave radios for I.D. in UDP
(5) Port Address 4131 Default Port Address
(6) IP Address 2 255.255.255.255 Default IP address that the radio calls in UDP
mode upon initial power up
(7) Port Address 2 6535 Port Address associated with IP 2
*NOTE: Once you set the "Ethernet Mode" to 1 (Menu 0, Submenu F, Item 0), you can no longer
change the "Set-Up Port" (Menu1, Item D). Therefore, first change the "Set-Up Port" to "2", then
change the "Ethernet Mode" to "1".

Installation:
To install the modem, proceed as described in the Main Manual, with the following
exceptions:
•Connect the modem to the LAN with a CAT5 RJ45 Ethernet cable.
•Use the "Normal/Crossover" switch to select the polarity of the Ethernet
connection. If connecting to a switch, router or hub, select "Normal". If
connecting to a NIC or a modem, select "Crossover". However, if you are
using a crossover cable, then use the opposite settings of the switch.
•If required, use the top row of LEDs for troubleshooting the Ethernet Interface.
Troubleshooting:
To troubleshoot the modem, proceed as described in the Main Manual. Additionally,
use the top row of LEDs in this Ethernet modem as troubleshooting tools.
•No data is being passed between the LAN’s.
Upon power up, the ethernet interface’s MAC filtering table can become
corrupted, and must be reset, or allowed to timeout. After power up, press
the reset button on the back of the FreeWave ethernet, or allow 4.5 minutes
to pass and the table time to reset.
•The LINK LED is off:
The Modem is not successfully connected to the LAN.
Make sure that the Modem is powered On.
Make sure that the Ethernet device connected to the Modem is On.
Make sure the Modem and the Ethernet device are connected with a good
Ethernet cable.
Try flipping the "Normal/Crossover" switch to the opposite position.
Check that the Ethernet device attached to the Modem is either set for auto-
detect, or for 10BaseT.
•The TX LED stays on:
Data isn't going from this modem's LAN to the other modem's LAN.
Make sure the radio link is working (see Main Manual).
Make sure both modems are linked to their respective LANs (the modems'
LINK LEDs are on).
•The RX LED stays on:
Data isn't going between this modem and its LAN.
The Ethernet device to which this modem is connected isn't receiving data.
•The COL LED flashes:
There are collisions on this modem's LAN
This is normal when the modem's connection to the LAN is through a hub (it
simply means that two Ethernet devices tried to send data through the hub at
the same time). The Ethernet network is designed handle such collisions.
This doesn't happen when the modem's connection to the LAN is directly
through a switch, or to a NIC, or to a router.
•The ERR LED flashes:

A data buffer is getting full.
This typically only occurs if the settings in the radio are incorrect. This also
occurs when the radio link, or the LAN link are not present. Check the radio
settings, the Radio Link, and the LAN link.
Try pressing the push-button on the back panel to reset the Ethernet
Interface.
