Amplifier Communication and Protocol, Octagon ISA CPU
Simulate Front Panel Input, Continued
Alternate Parameters (for Xicom's digital outdoor controller):
'L': Toggle Local/Remote.
'A': Toggle HPA/AC Power.
'H': Toggle HPA heater standby.
'!': Toggle HPA High Voltage.
'F': Fault Reset.
'8': Up Arrow.
'E': Enter.
'2': Down Arrow.
Notes :
If communicating with an amplifier via Xicom's digital outdoor controller, reference the alternate
parameter list. Otherwise, use the standard parameter list.
Rack amplifiers normally require that the enable key be pressed to process certain front panel
inputs. However, this is not a requirement for processing simulated front panel input.
Parameters 'I', 'J', 'K', and 'L' initiate Goto Power sequences (see commands 'D' and 'E', Goto
Power.) Goto Power sequences typically take several seconds for the power to reach the
desired level. For faster response, use parameters 'i', 'j', 'k', and 'l', which simulate encoder shaft
input. However, the HPA must be in the correct screen (i.e. Status1). The encoder shaft is also
used to scroll the fault log screen and to adjust settings on the linearization screen.
