NS-Link Driver Troubleshooting
This table includes some tips related to NS-Link drivers.
NS-Link Condition Explanation/Action
Need to program IP
address into the
device.
Before programming an IP address it is critical that the
unit be operational and passes the power on tests when
configured for the MAC address.
Note: If the unit is NOT operational, do NOT attempt to
program or use an IP address with the unit.
This is a general procedure for drivers on Microsoft
operating systems.
1. In the Comtrol Setup, highlight the Comtrol device.
2. Select Properties.
3. Select IP Programming.
4. Select Retrieve and confirm or modify addresses as
necessary.
Note: Enter in all 3 categories. The unit must have
Address, Mask and Gateway IP values entered.
If you do not have a default gateway address, try
using the ID number assigned to the PC that has
the NS-Link driver installation.
5. Select Program.
6. Select Reset - power LED should begin blinking.
7. Select Device Setup.
8. Uncheck MAC.
9. Check IP and enter IP number that you configured
earlier.
10. Select Ok (several times) and reboot the system.
IP addressing will now be in effect.
Cannot open port
1. Verify that MAC address in the NS-Link driver
matches the address on the Comtrol device.
2. Verify that you are using the correct NS-Link driver. If
necessary, remove and reinstall a new driver.
3. Isolate the unit from the network (see Page 81).
4. Check to see if another program or computer is active
on this port.
The Comtrol device
has a lower
limitation of network
bandwidth
requirement of 64
Kbps.
At this speed the entire available bandwidth is required for
the purpose of uploading the firmware from the driver to
the Comtrol device. At lower speeds, timing issues will
prevent the firmware from being successfully installed to
the Comtrol device, thus preventing the device from
normal operation.
When using the Comtrol device over a WAN link that is
less than the recommended 64 Kbps, a timing modification
may be made that will allow uploading of the firmware.
Load the driver locally to the device for the purpose of
getting the firmware installed. The PC on the other side of
the slow link can then “share” the port. The sharing may
be exclusive as the firmware loader PC may not need to
access the ports.
