Simple Telemetry?
Would it be possible to use a device such as this to remotely monitor the output of a DL-2 unit? The application would be in a FSAE vehicle on a course no larger than 100m in any direction from the pit area, so range would not be an issue. In theory, adding a null modem cable in the stream should not change the behavior of these transmitters.

hi Guys i perchased on ebay from hong kong Wirless Serial cards on 915mhz
these cards are limited to 19k2 transmission but i configured the DL1 down to 19k2 and hey presto i have wirless Telemetry they use 5V so conecting to the ref [5v] on the DL1 was easy and 5v is found on a laptop on the USB port so powering both devices is simple enough
the range tested so fare is almost 650 meters not bad concidering no line of sight so im impressed the cards cost me 75 quid for the pair a little wiring and soldeing of 9pin D sockets and total spent with small project box from RS was a little over 90 pounds
i have configured the monitor with a typical car dash look and all the data work live even at the slower speed of 19k2 i notice RT use 112k serial speeds i looked into Wirless serial cards with 112k speeds and WOW there exspencive over 300 pounds for the cards alone.
ill post some pictures of the cards and my installation at the week end as im working away
