SYSTEM PREFACEUSER MANUALSample Text here sample text here sample text here sample text here sample text here sample text here sampleGENERAL INFORMATION OF SYSTEMThis version of the OE5JFL tracker is based on the original version from Hannes OE5JFL.It was intended to be a DIY version with some extra features added by Hannes over the years.This “stripped down” single PCB version is mainly for use with the Megatron MAB encoders.It also uses external High power H-Bridges for more motor current.SYSTEM OVERVIEW Tracking of moon,sun,Cygnus,Sagittarius,Cassiopeia,Taurus,Leo and Aquarius Azimuth and elevation motor controlling for all targets plus two free choice positions Transmission of antenna position via LAN cable from antenna down to the controller in the shack Standard interfacing with absolute encoders : 10.12bit , MAB25,ETS25,MAB28,HH-12 With optional hardware: USdigital A2-S-S, Prosistel inclino,incremental encoder Selectable stepsize for tracking Selectable offset for azimuth and elev. up to /- 9.9 deg Motor control output cw/ccw up/down, including soft-start and soft-stop (by PWM) Local operation by 4 buttons at controller, non volatile storage of all parameters Real - Time – Clock 4 x 20 character LCD – display DC motor H-bridges for AZ and ELUSER MANUAL
NEW FEATURES Automatic calibration of the encoders by Sun or Moon position Support of new encoders (MAB28,ETS25,Positel inclino) PWM speedcontrol in manual mode with CW,CCW,UP,Down buttonsPCB overview A single layer PCB (large tracks wire jumpers) DIY External H-bridges (high power, low cost) USB to serial converter PCB headers for external buttons and leds All new features present on PCB headers Almost all components thruehole & DIL Megatron encoders via a PCB header (use own connectors) IC buffered inputs and outputs (encoders & H-bridges) LCD via PCB header (large LCD possible 4x20)USER MANUAL
