I have another Ethernet issue on an RCM6750. I power up the module with an Ethernet cable attached, it powers up fine. I then unplug the Ethernet cable, my app correctly detects the disconnected cable and brings Ethernet down. When the cable is plugged back in, the Net.Lib crashes and the module reboots. Here is what I do: void CheckCable() if ( !pd_havelink( IF_ETH0 ) ) { if (ifpend...

I have discovered an interesting mode of operation for the Ethernet interface on the RCM3900. With Ethernet configured for DHCP mode, either power up the module without the Ethernet cable plugged in, or unplug it after power up. You will find that after a few minutes the Ethernet controller chip (Asix) gets very hot. Hot enough that you can't keep your finger on the part without burnin...

I'm looking into developing a product for classroom monitoring that would communicate over ethernet and be powered by 802.3af compliant "Power Over Ethernet". Since I'm not trying to reinvent the wheel, I'm looking for a cheap microprocessor solution like the Rabbit modules where I can get the ethernet and web server aspect pre- built. The Ra

Just got back into some RCM6750 based work and am sorting out a little problem. I noticed that when I had my board plugged into a hub, every now and then ethernet connectivity would go away. Board was running other stuff, but nothing was making it out of the stack. Diagnosing this now, and I isolated the device's ethernet connection to a PC, run a homemade icmp flood on it, and I can ...

Hi, We r working on a project called icubec which is nothing but lighting controller.we have to use 10Base-T ethernet using RCM4000.So please anyone tell me which protocol we have to use for the ethernet as there is so many protocol like TCP,UDP,PPP,Telnet,FTP etc.I am confused which protocols to use for my application and plz tell me whether i can use sample code provided by Rabbit.Waiting for e...

Hello, I need to test performances of a RCM 3200 sending UDP datagrams on a LAN. In order to make those tests I need to exclude autonegotiation on the Ethernet, and manually set parameters like speed and duplex. How to do that? Any document to read for better explanation? My RCM3200 mounts an ASIX AX88796 as Ethernet controller. Thanks,

Hello, I have a working board that uses an RCM4100. I need to switch to RCM4000 due to the ethernet support. No problem no different pins, I checked the datasheet with my schematic. Anyway I have some difficulties: 1) the RCM4000 requires a 20MHz clock (not doubled) in order to get the ethernet working. With such a clock I'm not able to get the correct baud rate for serials (9600, 57600,...

Hi I am using a RCM2110. I code a small "server", it opens a Tcp socket in listen. Until a client connects to the Rabbit, it doesn't transmit/receive packets. So the application has to check the Ethernet connectivity. I unplug the Ethernet cable from the RCM2110 RJ45 socket, the network LED turns off, but the tw

Hello Friends, I have been using BL2600 for my projects to communicate with Touch Screen Panels via Modbus TCP. I used a cross over Ethernet cable so far because I used one to one connection. Now I tried to connect two BL2600s to one single Touch Screen via an Ethernet switch using straight through cable. This works fine, but when any of the BL2600 looses physical connection it cannot pic...

Hi, I'm in need for a VCP (Virtual Com Port Driver) for the Serial Ethernet Application Kit. I would like the driver to make an additional Com port on my computer that then connects to my development board. Then any serial program on my computer can send/receive information to the development board via ethernet. Would any one know if any exists?

Below is a posting I made on the Softools WinIDE group, I have posted it here because I think the possible fault may apply to DC as well as Softools as they or both based on the same TCPIP stack.

Hi everyone! I have a big problem with ethernet on my RCM3700 core module: even on its dev board, I can compile everything, and all works fine. But when I make an init, a sock_init for example, i.e. when I try to access the ethenet port, the software is regularry downloaded in the rcm flash, but when the sw goes in execution I have no power on the eth. sta

Hello all, I'm using the WiFi application kit, and I'm trying to figure out how I can change the IP Address at runtime. I have tried using the ifconfig function, but it just doesnt seem to work. The thing that confuses me is the first parameter of this function, IFETH0. This specifies the ethernet interface, but I'm not using ethernet - I'm usin

I'm trying to add Ethernet IP protocol as used in Allen-Bradley PLC's to my existing design. The Open DeviceNet Vendor Association has the protocol specifications and sample C code on their web site, but the code was written for the Microsoft Windows platform. I'm looking for anyone who might have already ported some or all of the code to the Dynamic C platf

Is anyone having reliability problems with the RCM3720? We have used several hundred RCM3720s in a product we build. After a few days to a few months the RCM3720 will lose the ability to connect via Ethernet, the on board Ethernet controller gets hot and the RCM3720 will not respond even to RFU.exe when we get the product back from the field. The RCM3720 operates in a benign environment:...

Hi, It seems that my RCM3200 module has problems connecting to my 10/100 Mb 3com switch. It auto switches to 100 Mb, though it does not establish a connection. If I use my (old) 10 Mb switch, it works ok. On the Rabbit semiconductors website I saw that there were some problems with the RCM2200 ethernet interface and a fix is available.

Has anyone attempted or been successful in adding IP routing functionality to the IP libraries on the rabbit? I want to be able to route packets back and forth between a serial PPP interface and the Ethernet interface on an RCM3000. It seems that it would require some tweaking to the IP.LIB and possibly some of the other libraries to implement this fun
