{Espanol} No discrepar con David Nelson, pero DH+ requiere generalmente un tercer alambre para el protector trabajar óptimo. Usted no menciona qué procesador y qué distancia aparte son. Si usted puede comprar y funcionar el alambre entonces considere Ethernet, ControlNet o DH+/DH485. {English} Not to disagree with David Nelson, but DH+ usually requires a third wire for shield to work optimally. You don't mention what processor and what distance apart they are. If you can buy and run the wire then consider Ethernet, ControlNet or DH+/DH485. Edited 2 May 2006 by BobLfoot
