#
# Measurement Computing Corp. CB-7050 digital I/O module
#
# This is "laboratory quality" power control as it requires wires 
# connected directly to motherboards and some hand tuning of delay values.  
#
# Ref: CB-7000 DIO User's Manual
# 
# Notes:
# - Important note: CB-7050 data lines are not isolated and share a common
#   ground.  Beware of ground loops!
# - Wire DI[0-6] to +5V side of reset header
# - Wire D0[0-7] (open collector) to +5 side of power switch header.
# - Wire the CB-7050 ground to moboard ground (send to reset/power headers).
# - CB-7050 is presumed to be at address 01
# - CB-7520 RS-232 to RS-485 converter connects to Cyclades TS at 115000 baud.
# - DO lines are "open" (0) at power on.  Writing 1 connects the line to gnd.
# - DI7 is n.c. on the CB-7050. Although plug 7 can be controlled via D07,
#   power state will always be "unknown" and on/off are effectively toggles.
# - [HDAMA] power on delay = 2s, power off delay = 5s.  Tune for your moboard.
# - This would be cleaner if we could call status_all from off|on scripts.
# - This would be cleaner if we had "whileon|whileoff" (no hard coded delays).
