Controllers and commands
Legend domes are typically controlled from at least one controller keypad. See Starting from a keypad on
page 8 for a list of compatible keypads and controller protocols. Refer to your keypad’s manual for instructions
for operating domes.
Also, to help you understand the difference between actions versus commands and their priority, see Actions
versus commands on page 70.
Autopan limitations
When setting autopan limits, be aware that you must set both the right and left limit in the same tilt hemisphere.
You can set them in either tilt hemisphere, but you cannot cross tilt hemispheres, meaning that you cannot pass
the bottommost point or turn the camera upside down. Allowing the camera to E-flip will create an invalid set
of autopan limits that may cause unexpected camera performance. See
Speeds/Tracking page on page 72.
Remember that there is a positive and a negative hemisphere. Depending on what coordinates you selected
under
Setup | Preferences | Coordinates , the positive hemisphere will be identified by a tilt position of
0° to 90° or +90° to 0°.

Keypad limitations for calling up presets
Most keypads have a limited number of preset numbers they can call up. (When you call up a preset, you are
using a preset command to move the dome’s camera to a preset position.) If you have a GE KTD-405 keypad
with firmware v1.2.09 or later, and it is operating with Impac RS-485 protocol, then you can call up all 127
preset numbers (1 through 127) directly from the keypad. If, however, you have a GE KTD-405 keypad with
an earlier version of firmware, or it is operating with Digiplex RS-422 protocol, then you can use the keypad to
call up only the first 63 preset numbers (1 through 63). If you are using presets 62 and 63 for your left and right
autopan limits, then you have a total of 125 or 61 preset numbers that you can call up from the keypad.
To verify your keypad’s version, press and hold the mon key on the keypad, until the keypad beeps, then press
the key.
