4.2. The LCD Screen

The 8401 HC is designed to use for both iOptron’s equatorial (EQ) mount, such as the SmartStar®-PR GOTO German Equatorial Mount and the GOTONOVATM Equatorial Kit, and AltAzimuth (A/A) mount, which includes all SmartStar® GOTO mounts and telescopes. It consists of a large 8-line LCD screen, which displays all the information as shown in Figure 18. The user interface is simple and easy to learn.

•GPS status: When the power is turned on, it shows “GPS ON”, which means a GPS receiver is connected. When the GPS receiver finds the satellite and receives GPS signal, it shows “GPS OK”. The “GPS OK” may turn off after few minutes.

•Slew speed: It has 9 speeds: 1X, 2X, 8X, 16X, 64X, 128X, 256X(1º/sec), 512X(2º/sec), MAX(4º/sec).

•Tracking speed: It has 4 speeds: Cel (celestial), Sol (Solar), Lun (Lunar), Def (user defined)

•Mount Type: EQ is equatorial and A/A altazimuth.

4.3. Connection to a Computer

The GOTONOVA hand controller has a USB port which can be connected to a computer. This will allow Firmware Upgrading, Database Updating, or Planetarium application. A USB2COM driver is needed to simulate the USB port to a RS- 232 serial port. (see Appendix D)

The MiniTower ProTM can be controlled by a number of popular astronomy software programs. For astronomy software that does not have an embedded iOptron mount driver, an ASCOM driver and related platform are needed. Please refer to Appendix F for more information.
