8407+ or 8410 hand controller (HC) works with a CEM40 mount. Shown in Figure 12 is an
8410 HC. The difference between an 8407+ and an 8410 is if there is a RS232 port on the HC for firmware
upgrade. The HC 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) at the bottom.
The CEM40 mount can be operated without the hand controller attached if it is controlled via a
SmartPhone/Tablet/Computer.
