xbee-adapter

[ddlawrence]

Hi. I want to interface 2 PlugaPodS together via
the stackable xbee adapter for a wireless control interface.
I believe I want a pair of xbee-adapter-ttl. The PlugaPodS talks
to the xbee via ttl DIN/DOUT on J3. Is that correct?
BTW, is the DIN/DOUT for the Serial Peripheral Interface?

Why is there a xbee-adapter-232? Is there some advantage
or feature? I would like to resolve this before I order them.

Do you sell other Maxstream stuff like RF cables & antennas?

thanks....don

The 'Pod talks to the XBee serially. It can do that at TTL levels, or it can do it at RS-232 levels.

BTW, is the DIN/DOUT for the Serial Peripheral Interface?

No, it is the SCI (Serial Communications Interface). This is the standard NRZ Asychronous Serial Port.

The SPI (Serial Peripheral Interface) is a Synchronous serial, basically a bi-directional shift register. Hence the word "peripheral" meaning something that can be added with a simple shift register interface.

Why is there a xbee-adapter-232? Is there some advantage or feature?

In the case of the 'Pod with one serial port, a version of the serial port appears at RS-232, and also at TTL. We also have other boards besides just the 'Pod's and some of the ARMs have two serial ports, and one is routed there. Having a RS-232 version and a TTL version allows either of the ARM ports to be used.

We can sell you anything you want in the line. We may not have the best prices, because if we don't order in volume, there isn't much in the way of discounts or margins we can get. But we will and do supply others with the antenna versions of the XBee's. We just don't show them on our website, as we are trying to improve volumes on the commonly used devices.
