Sonodyne AM21P - Manual (Page 15)

Command: Standby Mode (PGRN)
This command is used to get/set whether or not the amplifier is in Standby (power-saving) mode.
In this mode, the amplifier is shutdown. This parameter operates in a logic OR fashion with the rear
panel Standby input. If either the rear panel input is active or this parameter is active, Standby mode
is active.
%PGRN:xx<CR>
If xx = 00, then Standby mode is de-activated and the amplifier operates as normal. If xx = 01,
then Standby mode is activated.
When Standby mode has been changed (from either GUI or external comms), or the current
value has been requested, the amplifier will send:
%PGRN=xx<CR>
Where the return values are:
➢ 00 = Normal mode
➢ 01 = Standby mode
To request the current value, use:
%PGRN:??<CR>
Command: Amp Status (PAMP)
This command is used to get the status of an amplifier.
%PAMP:x??<CR>
Where x is the amplifier to select (between 1 and 4). The AMDXY00P will reply with:
%PAMP=xyy<CR>
When the AMDXY00P replies, the yy section of the command can range between 00 and 02.
These values should be interpreted as:
➢ 0x00 = Amplifier OK
➢ 0x01 = Amplifier in thermal shutdown
➢ 0x02 = Amplifier in fault shutdown
NOTE: that this command must be polled; the amplifier will not send out amplifier status
information on the RS232 port unless explicitly requested by sending the command.
Command: Version Info (PVER)
This command is used to get the device and firmware information.
%PVER:??<CR>
The amplifier will reply with:
%PVER=AMDXY00P,aabbcccc<CR>
Where XY can be 21, 22, 41 or 42 and represents the device model.
aa is the firmware major version number (can range from 0x00 to 0xFF).
bb is the firmware minor version number (can range from 0x00 to 0xFF).
cccc is the firmware revision version number (can range from 0x0000 to 0xFFFF).
