I have a Tracvision S2 installed and was using the RCA DRD486SH which has apparently died. I read on the KVH website there are issues with the low speed data ports but, until this one died, it appeared to be working okay. I see Sadoun offers the RCA DRD435RH which looks to be similar. I want to confirm this will work with the S2 and the LSDP before ordering. I asked KVH support and they referred me to 2000 Networks is an Authorized Reseller of DirecTV Satellite TV hardware. and wouldn't answer the compatibility question above. Sadoun pricing is FAR better!

Any advice?
