All,
This had nothing to do with the TS-RF2-AERO card, per se.
The problem here is that I had too many devices drawing power from the
TS-ENC720 enclosure's 5VDC voltage regulator. Installing the JP7
jumper cures the problem by providing much more power to the
peripheral devices by bypassing the on board 3.3VDC voltage regulator.
The description here could have been: TS-7260 +
TS-ENC720 + WiFi USB + USB Flash + P/C 104 Aerocomm Board + GPS =
Straw that broke the camel's back
The way I understand it, the 7260 ships with JP7 open, meaning that
one can supply 4-25 VDC to it. When shipped with the TS-ENC720
enclosure, the regulator on the enclosure's board is supplying a
regulated 5VDC to the 7260. Since JP7 is open, one is supplying a
regulated 5 VDC to 3.3 regulator, which then boosts it back up to 5VDC
before supplying the USB and LCD circuits.
By closing JP7, the regulated 5VDC from the enclosure is routed
directly to the USB and LCD circuits, a more efficient mode of
operation that makes more power available to the peripheral devices.
All of this is pretty clearly spelled out in Section 5.11 of the
TS-7260 Hardware Manual (p. 40). However, when my new computer
started rebooting spontaneously every 45 seconds or so, that wasn't
the first place I thought to look ;)
Once I installed the JP7 jumper, and plugged back in the full
compliment of devices, I powered both boxes up and they ran overnight
without rebooting.
Back on the AERO board:
On the two machines with AERO cards, I then
1. copied the tsuart-rf.o file from the flash into by Debian file
system (/lib/modules/2.4.26-ts11/kernel/drivers/serial/)
2. ran depmod
3. ran modprobe tsuart-rf (creates /dev/ttyTS0)
4. ran minicom, setting the serial device to /dev/ttyTS0, 57600 8N1.
Also deleted modem init string. Don't know if that was necessary
5. typed text into a minicom window on one machine and it appeared in
the other minicom window on the other machine. Reversed the procedure
by typing in the other window, which worked as well.
Thanks to Eddie and Engineers.
