Display will stay on for [minutes]. If [minutes] =
0 display will stay on permanently. Maximum
value for [minutes] is 100.
Turns off display.
Loads new startup screen (40 characters).
Screen is saved for subsequent power ups.
Turns a general purpose output OFF. [gpo #]
may be from 1 to 6. See section 2.2 for further
details.
Turns a general purpose output ON. [gpo #]
may be from 1 to 6. See section 2.2 for further
details.
Value is write address and must be even, read
address is 1 higher.
Reads the module type. See table in section
6.1.9. This will return a 1 byte hex value.
Sets RS232 speed. See table in section
6.1.10 for values of [speed]
This is a one-time-use command which works
only on units without factory set serial
numbers.
Reads the two byte serial number of the
