Section 4. Programming the SDM-SIO4

testio [test#]

This is used by Campbell Scientific for test purposes.

Each test command is carried out for 2 seconds. Test# can be in the range 0-255; only five test numbers are currently valid, as shown below.

testio returns

test 0 DTR,RTS,IO=LOW

test1 DTR=HIGH,RTS,IO=LOW

test2 DTR=LOW,RTS=HIGH,IO=LOW

test3 DTR,RTS=HIGH,IO=LOW

test4 DTR,RTS=LOW,IO=HIGH
