Rabbit Forum – I need lots of TTL in and some drivers out. I would like to hook up about four rabbit net I/O cards 🙂 . However, it seems there is no hub product yet, and the “network wiring” appears to be point-to-point. 😕 “A typical RabbitNet system consists of a master single-board computer and one or more peripheral cards.” (The BL2500 handles one and BL2600 handles two max.) With all due respect Steve, perhaps a more descriptive name would be “rabbit ambilical”. $250 is high overhead for each master controller… What can I do? I desire 10 feet between nodes, comms rs485-like characteristics. What is in the near future? kindest regards, \*the other brian ---

There is a RabbitNet Hub available, but not made by Rabbit directly. It is made by a third party partner and can be found at: [http://www.rabbitconsulting.com/partners/prod.cfm?id=109](http://www.rabbitconsulting.com/partners/prod.cfm?id=109) There is also the option of building a hub into your product using the new RIO chip. This chip has the ability to be configured as the heart of a RabbitNet hub, and only needs the RS-422 transceivers and a clock source as external components to create up to a 7 port hub.
