If the NS or NET LED is not solid green then check the recommendations below:

1) For networks running at 57k6 or 115k2 bauds it is necessary to have 150 ohm resistors on each end of the network (for 230k4 use 82 ohm resistors)
2) Ensure that at least 10' or 3 meters of cable is used between gateway and any surrounding nodes
3) Ensure that the outer braided shield has been grounded in one place to reduce noise
