FEATURES
The M2 RC2800PRKX1SU is our Mid Grade rack-mount controller. The RC2800PRKX1SU was developed for "Commercial Grade"
Polarity Pedestal Models.
The M2 RC2800PRKX1SU uses a Microchip PIC18F2520-I/SP for Micro processing user commands, M2 software and EEprom for
memory. User modes include: (3) Operational / Run Modes and (10) programmable presets.
The M2 RC2800PRKX1SU uses PWM (Pulse Width Modulation) for speed control, allowing for full torque at the slowest input
speed. Location heading from the motor assembly is supplied via an Open Loop Circuit to the controllers' microprocessor.
The M2 RC2800PRKX1SU software also includes a full GUI software for setup and run modes and a Interface Control Document
(ICD) is supplied with the RC2800PRKX1SU.
Computer interface to the RC2800PRKX1SU is via an RS232 port.

Page 5: Run Modes
BASIC OPERATIONS / RUN MODE DESCRIPTIONS RUN MODES: Modes 0, 1 and 2 are all run modes capable of activating the positioner in both the CCW / DWN and CW / UP direction. MODE 0 = MANUAL OPERATION MODE: Pushing the CCW button activates the positioner in the Counter Clockwise direction, and the Heading count will go down. - Page 6 M2 SETUP UTILITY INSTALLATION & OVERVIEW MINIMUM COMPUTER REQUIREMENTS AND HARDWARE: 500 MHz Intel Pentium II or equivalent Computer (Preferably a Laptop) 256 MB of RAM / 1MB of Disk Space Windows 98 / XP / Straight through DB9 RS232 Serial Cable INSTALLING THE M2 SETUP UTILITY SOFTWARE: In most cases the controller will be pre-configured at the factory.
- Page 7 M2 SETUP UTILITY OVERVIEW CONTINUED... New Heading: Change or type the desired heading value and click on “Go.” The “Stop” command will immediately stop the current motion. Change ID: Changes the ID Byte as stored in the controller. This can be used to identify a specific controller board and controller based upon your usage.
- Page 8 AZIMUTH SYSTEM CONFIGURATION Each Axis of the RC2800PRKX3SU needs to be configured for a spectrum of use and position of limits. The programmable limits in the RC2800PRKX3SU control, give the ability to specify the amount of travel around a spectrum of use. The AZ/EL/POL 3 axis positioner has physical limits CCW / DWN and CW / UP. The limits provide physical stops for safety due to control box failure.

UNDERSTANDING MIN / MAX SPEEDS & RAMPS SPEEDS AND RAMP OVERVIEW: Depending upon your particular system needs, you may find it necessary to adjust minimum to maximum speeds and ramp time durations. EXAMPLE # 1 EXAMPLE # 1: If your system is a very large Dish or Phased Array with a lot of weight, wind area and inertia, it may be necessary to increase your maximum ramp up and ramp down duration. -
Page 15: Connections And Start Up
CONNECTIONS AND START UP CONNECTIONS: Once the Azimuth, Elevation or Polarity units have been wired up at the motor end, start the process of wiring the correct color wires to the rear of the control unit. Use the table below for proper wire color and terminal number. Each individual 12) position terminal strip, has been clearly marked to help with proper connection points. - Page 16 AZ/EL/POL PHYSICAL LIMIT SWITCH PRE TEST LSK-1000 OVERVIEW: The LSK-1000 limit switch kit is a physical hard backup limit. The standard control unit supplied with our AZ, EL or Polarity Unit has “Electronic Limits”, but the LSK-1000 limit switch kit, has been designed as a physical backup system in the event of a control unit failure.
- Page 17 AZIMUTH AXIS SETUP AND CALIBRATION AZIMUTH SETUP AND CALIBRATION: 1. Connect a straight through DB9 RS232 serial cable to the rear of the RC2800PRKX3SU controllers’ “Azimuth” port. Now connect the RS232 serial cable to your laptop or desktop computer being used for setup. 2.

Page 21: Troubleshooting Error Codes
TROUBLE SHOOTING / ERROR CODES ERROR CODES: E1 = No Motion. The controller has not sensed a movement of at least “1” degree within the Motor Time out Value (which is defaulted to “4” seconds) E2 = Range Error. This means that the controller is too close to the most CCW / DWN heading allowed by the software. -
