IDSYMPTOMPOSSIBLE CAUSERESOLUTION
C100Unknown Device Type is displayed under Live Folder in Project Window. Possibly accompanied by a blue Drag Net shield with a question mark over it. Also may see [192.168.69.22] following the words Unknown Device TypeThe RPM's current IP address is incompatible with the PC's current IP address. 192.168.69.22 is the default Rane IP address we ship units with. It is normal to see this address with Unknown Device Type when your computer's IP address is not on the same subnet as the Drag Net device.Run the Configure Hardware IP wizard (Tools menu) to set the RPM's address. See "Connecting to a Live Device for the First Time" in Drag Net software's Help. TIP: If you set your computer's static IP address to 192.168.69.69 you should be able to poll and find your RPM Live Device.
C101Polling for Live devices fails to find any RPM units.Firewall software is blocking responses from the RPM. Or, anti-virus or system diagnostic software may be disrupting communication.Disable all firewall, anti-virus or system diagnostic software. Note: Windows XP includes a "hidden" firewall which may need to be turned off as well. To disable, right-click the desktop's My Network Places icon and select Properties. Right-click the Network Connection used with the RPM and select Properties. Click the Advanced Tab and uncheck the "Protect my computer and network by limiting..."
Windows may be Polling out the wireless NIC or another network adapter that is NOT connected or "talking" to the RPM device. (Yes, Windows does this often - even though your wireless is not connected and/or it's physically switched off! And no, we at Rane have no way to fix this except what's in the Resolution column to the right.)Disable your wireless NIC and any other network adapters that are NOT "talking" to the RPM device.
Incompatible Network Interface Card (NIC). Users have reported problems when using Xircom cards. Try another PC, or swap out for another NIC.
Two devices on the network (PC & RPM; two RPMs?) have the same IP address.Use a unique IP address for each device.
NIC card does not support 10Base-T.Force NIC card into 10 Meg speed.
Hub or switch on network between PC and RPM is 100Base-T only.Connect directly to RPM unit or use a hub or switch which is 10/100Base-T rated, (i.e. dual speed).
C102LINK light on rear of RPM or Network Interface Card (NIC) flashes intermittently or stops.Know issue with certain Xircom NICs.Try another PC, or swap out for another NIC.
C103LINK light on rear of RPM not lit at all.PC and RPM are connected using a straight-through Ethernet cable instead of a crossover cable.
Notice: Undefined variable: d in /var/www/html/dtchart08.php on line 71
Connect the PC and RPM directly using the crossover cable supplied with the unit.
Ethernet connector not fully seated on RPM.Disconnect and re-connect the Ethernet connector, ensuring a firm fit.
Network Interface Card doesn't support 10Base-T Ethernet.Replace NIC with one that supports 10Base-T. Most commercially available NICs are Dual Speed, supporting both 10Base-T and 100Base-T (Fast Ethernet) modes.
Possible bad Ethernet jack.Contact Rane tech support @ (425)355-6000.
C104While transferring from Storage-to-Live or Live-to-Stroage using Drag Net 4.0.x, I get an "Invalid Parameter" or a "Connection Lost" messageSome programs upon installation, some IT departments, or some ISPs alter the registry's "MTU" value which reduces the maximum Ethernet packet size a PC is able to transmit. (MTU = Maximum Transmission Unit). When MTU is set below 1500, truncated packets are transferred to or from Drag Net devices causing invalid parameters or lost connection messages. Get “DR. TCP”, and check the MTU setting for the NIC used with the Drag Net device. If the setting is under 1500, reset it to 1500. A reboot is required after changing the MTU. DR TCP: http://www.dslreports.com/drtcp
IMPORTANT NOTE: It may be if you've encountered this problem, that your Live device and/or your Storage file contains invalid and incomplete data (bad parameter settings). It is recommended that you re-create your configuration file from scratch (we know this isn't fun) to be certain you're not wasting your time with corrupt data in a Live or Storage configuration.(1) Download the DRTCP021.exe file from the above web site. (2)Run the DRTCP021.exe on the PC that's talking Drag Net. (3) Under "Adapter Settings," select the NIC you are using with the Drag Net device. This NIC's MTU setting appears on the lower right. (4) If it's lower than 1500, change it to 1500 and hit the Save button. (5) Close everything and Reboot
The Windows program that reads this MTU variable is called Winsock.exe. When sending Ethernet packets between two devices on a network, it is possible for winsock to learn from the network router that a different maximum number of packets is required by the router. This is independent from the MTU variable in the PC Thus, even if you (or Rane) sets the MTU to 1500, it’s possible for something (i.e., the router) transferring packets to truncate the data on us. Rane is working on this. We've seen no one with this problem, but it's possible.
C105I can Poll and find the device, but when I try to update Firmware, I hit Transfer and nothing happens. No progress meter, no nothing.You're using an IP address on the device that contains a zero. ( NOT OK = xxx.yyy.0.1 or xxx.yyy.1.0 )Change the IP address of the RPM so all numbers are between 1 and 254. A single zero in any IP address field makes firmware updates impossible since we use a different protocol for firmware transfers versus Polling & device editing. Neither computer NIC or RPM unit can have a single zero ( 0 ) in the IP address. TIP: Using 192.168.69.69 for your PC network card static IP address should allow you to poll for and find an RPM unit without having to run the "Configure Hardware IP" wizard in Drag Net.
C106I'm using the same computer I did before when I setup the RPM, but now when I poll I cannot find my unit, just an Unknown Device Type.

IP address on computer was set to DHCP, (resulting in Windows automatically using 169.254.1.1) during original installation.
Always check to be sure you are not running DHCP in Windows (98 & 2000), when using Drag Net. The Configure IP Wizard lists in the 4th column if your NIC is running DHPCP. If this column says "Yes" - change your IP to Static (Use the following IP Address). TIP: Anytime you see the IP address 169.254.x.x the network device in question is running DHCP and using the fallback address.
Different version of Drag Net or firmware being utilized.Update firmware to necessary version (the latest firmware is always included within the Drag Net application) or use correct version of Drag Net. TIP: If you are going to change Drag Net version, you MUST uninstall the old Drag Net, before installing another version.
Crossover cable (the one supplied with the RPM) used, not connected directly to RPM.Correct network wiring. Use supplied crossover cable to connect directly from computer to RPM OR use a standard straight through cable to connect RPM to network along with Drag Net computer.

C107XP Pro IP SETUP TIP: I need to "Obtain an IP Address automatically" (use DHCP) on my PC when at my office to get email, etc., and I'm tired of manually typing in the numbers to "Use the following IP address" (Static IP) AND I have Windows XP Pro!Windows XP makes IP address setup and editing more difficult than Time-Life book's "do-it-yourself" Home Surgery guides.If you have Windows XP Pro, you can setup your IP address settings so that you “Obtain an IP address Automatically,” this allows your computer to obtain an IP Address from your network’s DHCP server when you’re on the network and you’ll be able to get email et al. Then, in XP, there’s an Alternate IP you can type in which is used when your computer figures out that its DHCP server is not there (i.e., when you’re not on your computer network at a job site). Setting it up this way saves you the time of manually having to toggle back and forth between DHCP (auto IP) and Static IP (type a specific IP address in).
C300Double click on Live device and the error message says: "Can't communicate with device at address -1, please check your RW485 connection."
Notice: Undefined variable: d in /var/www/html/dtchart08.php on line 71
You've changed the IP address of the PC and have not rebooted.
Reboot.
C301Polling finds the Live device, but Configure Hardware IP lists no Live units?You've recently changed the IP address of the PC and have not rebooted. (yes, even in XP which is supposed to not require rebooting; now it does for reasons beyond the intent of this troubleshooting chart)Reboot. Or, to save time, run the following DOS command from a DOS Shell: "arp -d xxx.xxx.xxx.xxx". [where xxx is the IP address of the Live device.]
C302I'm having trouble loading a configuration into my 2nd (or another) Live RPM device?You've recently unplugged the Ethernet cable from one RPM into another and have not Polled anew.Poll each time you plug into a new RPM. [You can also run the "arp" DOS command discussed in the above listing since this clears the MAC Address to IP Address table that's tracked by Windows.]
Hint: add the "arp" DOS command as a Shortcut in Drag Net's Project window to save mouse clicks and typing time. Or, get a 4 port network switch for your tool kit to talk to mulitple RPMs from a single PC without unplugging & replugging.
C303Once Polling for devices begins, the lower right hand Polling meter (green) lights only for a fraction of a second then Polling stops. The Polling button only appears to remain in the down/pressed position for less than one second.Your network IP address is not setup yet, or not working. You may have just plugged in the Ethernet cable and quickly started polling. Doing this without waiting until the computer has had time to recognize it's plugged in to a network and that a valid IP address has been established can cause Polling to stop very quickly.Wait until your network connection has had time to become valid before polling. This should only take one minute at most, but usually only takes a handful of seconds.
If your computer runs DHCP (Obtain an IP Address automatically), it can take up to a minute for your network connection to receive a valid IP address.Wait until your network connection is enabled and a network connection is found and valid before Polling.
