Hi - Working with XBee and RS485, successful sending data between radios, so they're paired. But if I try to send data through a shield instead of Digi's RS485 Adapter it doesn't work. So, it works if I talk through Digi's XBee RS-485 adapters at both ends but not with one Adapter at the (End Device/Router) <--> Shield at the Netduino (Coordinator).
Target configuration is:
Netduino
XBee Shield
XBEE COORDINATOR RADIO(XBP24BZ7, firmware 208C)
- talks to -
XBEE ROUTER RADIO
Digi XBee 485 Adapter ZB PRO S2B
RS485 Device
Using Digi XCTU for radio config, I suspect that the Netduino's XBee (Shield Radio, Coordinator) needs DIO7 & DIO6 set to "Digital Input" to tell it to expect to talk through the Digital Pins 0 & 1, rather than "RS485 Enable HIGH" (or LOW) as works when going through the RS485 transceiver.
Any insights anyone? Thanks in advance.

Since nobody is jumping on this, let me simplify the question:
When using an XBee shield on Netduino, what are typical XBee settings to talk through COM1 Digital Pins 0 (RX) & 1 (TX)?
In the above post/question, you can essentially disregard what device is attached to the radio at the other end. Basically if the radios are paired and you sniff the COM at the other end the data will get there. Whether the receiving (ROUTER) radio successfully sends the data it receives from the COORDINATOR out to an attached device (Netduino, computer, RS485 device or whatever) is a separate matter.
Trouble is, I don't see that the Netduino XBee shield (COORDINATOR) is sending out at all.
