Don't forget the Z3816A and the Z3805A. Both are seen with 24 VDC and 110 VAC options. The Z3816A (8 sats) has a DB9 RS232 port and the Z3805A (12 sats) has a DB25 RS232 port and both require a Null Modem adapter or cable.

Some are 24V. I doubt if you will find one for $200. EBay has one for $500 and another for $1000. A Trimble Thunderbolt needs +12, +5, and +12. EBay has one for $110 and 2 more for $250. In both cases, round up for an antenna. > I am willing to do some building and gathering to implement this, including > setting up a computer.

Neither the Z3801A nor the TBolt are setup to power the oven while the reset of the setup is powered down. -- These are my opinions, not necessarily my employer's.
