The PCB mounted inside the desktop housing is the 13.8v to 10v voltage regulator which provides a stabilized supply to the Pan & Tilt heads positional potentiometers.Īn external 13.8v supply is required in order to drive the high current motors of the Pan & Tilt head. The ERC-M kit is the top left PCB, the desktop housing is also a kit comprising of the LCD display and front panel buttons. The LCD display is showing the position in degrees, the number after Az or El is the feedback from the Pan & Tilt head, the numbers on the other side of the > are the output from the software, the ERC-M compares the two values and energises the appropriate relays which in turn operate the motors in order to keep the values aligned. The two yellow LEDs on the left hand side indicate the signal to the auxiliary relay. The main controller is a ERC-M USB kit which interfaces with the PC and programs which are running, the Rotorcard relays are controlled by the ERC-M, the Rotorcard also provides a positional feedback to the ERC-M.įront panel of the Desktop housing for the ERC-M, the front panel has manual buttons for up/down tilt & left/right pan, LED’s also show when a signal is sent to the Rotorcard relays. This blog is an update of this – Pan & Tilt Orbitron Interface post as I’ve added some pictures of the kit used and I have finally got round to putting the Rotorcards in a decent enclosure.
