2.5. Go2Nova
®
8407+ Hand Controller
The Go2Nova
®
8407+ hand controller (HC) shown in Figure 8 is the standard controller used on the
CEM40 mount. It has an integrated heater that ensures the LCD display will work at the temperature as
low as -20ºC(-4ºF). It has a large LCD screen, function, direction, and number keys on the front; a red
LED reading light on the back; and a HBX (6-pin) and a RS232 serial port (4-pin) at the bottom.
The CEM40 mount can be operated without the hand controller attached if it is controlled via a
SmartPhone/Tablet/Computer.
