3.9.7 Power-Up State (17 58)
The Power Up State setting determines whether, when powered-up, a unit should be Muted, Operating, or in
the state it was when it was last switched off.
A single enumerated byte is sent or received in this message.
30: Power Up MUTED
31: Power Up with RF ON
32: Power Up with output set as it was when last powered down
3.9.8 Parallel Output Functions (17 59)
The functions of the eight outputs on the Parallel I/O module can be read and controlled. The following table
lists the functions available. “Serial I/O Code” is the hexadecimal value of the byte that must be sent in the
message to select the function, or that is returned when reading back the currently set functions. “Function”
describes the overall meaning of the Parallel I/O output. “Contacts” shows the meaning of contact closure for
the two positions of the Form ‘C’ contact set; “N.C.” = “normally closed” contacts that are CLOSED when the
relay is de-energized; “N.O.” = “normally open” contacts that are OPEN when the relay is de-energized.

3.9.9 Output Power Calibration Offset (17 5A)
The output level is calibrated at a single frequency at the factory. At different frequencies, there may be an
error in the Pout reading due to the frequency response of the detector diode and the coupler. The Pout Cal
Offset allows the operator to enter a correction factor (in dB) to compensate for this error when operating at
different frequencies, or to correct for losses following the SSPA (for example, the power delivered to the
antenna can be displayed, if an offset equal to the transmission line loss is entered.)
