roaming | I believe the 2600 also is limited to 6 decimal places of precision on the coordinate string.
To figure out if you need a null modem adapter, you need to know which pin is carrying the "transmit" signal from the receiver, and which pin is the "receive" pin on the 2600 harness. These need to match up. If this requires a null adapter, then you need one. If they match without the adapter, then you don't. :-) | |
