1,2 = relay, 2A @ 28VDC or 0.5A @ 125VAC
      100 million operations w/no load,
      100,000 loaded
3 =   I/O 0
4 =   I/O 1
5 =   I/O 2
6 =   I/O 3
7 =   +5V regulated, 50mA dedicated power
8 =   Ground

Setting Direction of I/O Line(s)
--------------------------------
# Set Direction of I/O Line(s)
mbus /dev/io w 3,[direction]

where "w" means "write command", "3" means
"set direction" and "direction" is a value from
0-15 representing the four I/O lines,
1=input 0=output

0 = 0000 = all four lines set to output
1 = 0001 = line 0 is input, lines 1-3 are output
2 = 0010 = line 1 is input, lines 0,2,3 are output
3 = 0011 = lines 0,1 are input, lines 2,3 are output
...
15 = 1111 = all four lines set to input

# Example, setting all four I/O lines to input
mbus /dev/io w 3,15


Set I/O Lines (on lines configured as output)
----------------------------------------------
# Set I/O
mbus /dev/io w 1,[line]

where "w" means "write command", "1" means "set I/O"
and "line" is a value from 0-15 representing the
four I/O lines, 1=set 0=clear

# Example, setting line 0
mbus /dev/io w 1,0


Read I/O Lines (on lines configured as input)
---------------------------------------------
# Read I/O
mbus /dev/io w 2 r 1

where "w" means "write command", "2" means "get I/O",
"r" means read byte

A one byte value is returned. Only the low 4 bits
are valid, each bit representing the I/O lines 0-3

# Example, reading state of lines
mbus /dev/io w 2 r 1

If returned value is:

0, all lines are low
1, line 0 is high, rest are low
2, line 1 is high, rest are low
3, lines 0,1 are high, rest are low
...
15, all lines are high


Trigger Relay
-------------
# Trigger Relay
mbus /dev/io w 4,[relay]

where "w" means write command, "4" means "set relay"
and "relay" is the relay setting, 0=open 1=closed

In a typical setup, a closed value (1) would turn on a device
such as a lamp (see voltage/current limitations near top of
this document).

# Example, closing relay
mbus /dev/io w 4,1
