should either switch to the new frequency immediately, or stop briefly and then become operational
with the new signal. Otherwise, the risk exists that something such as a frequency sweep could
trigger off a new preset briefly or cause the device to misinterpret other signals, e.g. signals
intended for the Commander 1220. This could have undesirable consequences for the operational
status of the device.
The idle state of the RS-232 interface lies between –3 V and –15 V. However, in practice, 0V is
sufficient, as the switchover threshold on normal receivers lies 0.8V. The highest level of
the squarewave signal should lie b3 and +15 V in line with the RS-232 norm.
Preset Command Byte Frequency

1 0x80 600Hz
2
0xC0 685 Hz
3
0xE0 800 Hz
4 0xF0 960 Hz
The Preset 0 “SCRATCH“ should not normally be used to for remote control of the
ZOMBIE, as it is altered with every configuration through the COMANDER 1220.
