A UPBv2 and Pocket Powerbox Advance expansion accessory from Pegasus Astro.
The external motor controller (XMC) was designed to expand the focus capabilities of the “Ultimate Powerbox v2” (supports a 2nd focus controller) and adds focus functionality to the “Pocket Powerbox Advance“. The device does not require a USB cable and can be attached directly to the EXT port of the Powerboxes. It can drive a large bipolar or unipolar stepper motor with high precision.
Microstepping
Controller support micro-stepping which can be configured via software to Full / Half/ 1/4 step and 1/8 step. This provides additional precision and a smooth rotation from the stepper motor.
Supported Motors
Pegasus Astro has successfully tested and controlled the following stepper motors:
| STEPPER MOTOR | CABLE TYPE |
| Pegasus Motor Focus (v1 & v2) | Straight RJ45 Network Cable (included with XMC) |
| Starlight HSM 25 / 30 / 35 | CMOT-HSM |
| Starlight MSM 25 / 30 / 35 | CMOT-MSM |
| Starizona Micro-Touch | CMOT-MSM |
| Rigel nStep Motors | CMOT-MSM |
| Moonlite Stepper Motor | CMOT-RJ45DB9 |
| Robofocus Stepper Motor | CMOT-RJ45DB9 |
| Lakeside Stepper Motor | CMOT-RJ45DB9 |
| Lacerta Motor | CMOT-LCRT |
Please note that each motor requires its own cable due to different pin-out selection of each manufacturer. Unless noted otherwise, these cables are not included and are sold separately.
No USB port is required
You do not have to occupy a USB port as the controller does not require a USB connectivity. Just plug the RJ12 port into the EXT port and the controller will be recognized from the powerbox software. Simple as that!
Second EXT port available
A second EXT port allows you to daisy chain future equipment or connect your environmental sensor.
Protections
The controller is fully protected against under-voltage, over-current, and over-temperature events.
Specifications:
- Supply Voltage: 12V DC Preferred. Accepts 8.2V to 24V – depends on the motor
- Drive Current: 1.6 Amps per motor coil
- Motor Compatibility: Unipolar and Bipolar Stepper Motors
- Motor Output: RJ45 Socket
- Connectivity: RJ12 Socket (Straight RJ12 to RJ12 cable)
- Power Input Connector: 2.1mm Center Positive Socket
- Dimensions: 66mm x 66mm x 28 mm
