The Lcd Screen - iOptron CEM40 Instruction Manual


STOP/0 Key: Stop the mount during GOTO. Also toggling between starting and stopping
tracking.

HBX (Handbox) port: connect the HC to the CEM40 mount using a 6P6C RJ11 cable.

Serial port: connect the HC to a computer via a RS232 to 4P4C RJ9 cable. The pin-out of the
serial port is shown in Figure 9.

2.5.2. The LCD Screen

The 8407+ HC has a large 8-line, 21-character per line, LCD screen which displays information on the
status of the mount as shown in Figure 10.The user interface is simple and easy to operate.
1. Target Name/Mount Position: displays the name of the target that telescope is currently pointed to
or the current mount position.

Zero Position: The reference position for GOTO. The mount can move to Zero Position
using "Goto Zero Position" or "Search Zero Position" command;

User Position: The mount is pointed to a user defined position, which could be a particular
celestial object or simply a position determined by pressing an arrow key;

An object name, such as "Mercury" or "Andromeda Galaxy": Name of the star or celestial
object that the mount is currently slewing to or tracking.
2. Target R.A.: Right Ascension (R.A.) of the target object.
3. Target Declination: Declination (DEC) of the target object.
4. Right Ascension: Current R.A. of the telescope.
5. Declination: Current DEC of the telescope.
6. Altitude: Altitude of the telescope (degrees vertical from the local horizon - zenith is 90º).
7. Azimuth: Azimuth of the telescope (north is 0º, east is 90º, south is 180º, and west is 270º).
