information in the data field. The Neuron Chip continues to send the status request
command until it receives a frame with the RD/WR ACK bit set.
Network Connection
How you connect a Series 6000 device to a network depends primarily on whether the Series
6000 device contains an FT 6000 Smart Transceiver or a Neuron 6000 Processor. For FT
6000 Smart Transceivers, you use the FT-X3 transformer; for Neuron 6000 Processors, you
use an external transceiver and associated interconnect circuitry.
Connection for an FT 6000 Smart Transceiver
Figure 20 shows the preferred interconnection between the FT 6000 Smart Transceiver and
the FT-X3 Communications Transformer; the figure also shows the associated transient
protection circuitry. Connect pins 1 and 6 of the FT-X3 transformer to the FT 6000 Smart
Transceiver, as shown in the figure. The figure is not a complete schematic, because it does
not include the clock, reset, and power supply bypass circuits for the FT 6000 Smart
Transceiver. See Appendix C, FT-X3 Communications Transformer, for a schematic view of
the FT-X3 Communications Transformer.
