Breakout board for Accelnet Micro Module

• for Copley Controls Corp models : ACK-055-06, or ACK-090-04

Identification

• yellow tint PCB from AP-Circuits
• bottom side text label "medialab/copmm1.pcb", "06/06/05"
• dimensions : 3.36 x 2.21"

Connectors

• 7 position terminal block with removable screw terminal plug (may be 4 position)
• DB25 female
• RJ45 (8 pos) for RS-232 programming cable
• pair of female headers for mounting Copley motor amplifier

Indicators

• "V.MOT" is a dual red/green with intensity related to average motor voltage
• "HV.PWR" indicates the presence of the HV motor supply
• "+5V" indicates the presence of 5V from Copley motor amp

Errors

• Need to switch RxD and TxD on the RJ11 connector. Do this by cutting traces and adding jumper wires.

Designs

• SCH (REV-0) 06-06-05
• PCB top (REV-0) 06-06-05
• PCB bottom (REV-0) 06-06-05

• Gerber files and Tango DOS source(Rev-0) 06-06-05

• Preliminary schematic 06-02-05
• Preliminary PCB 06-02-05

Reference

• Copley Amplifier Datasheet

Future Revisions

• change LED to gull-wing such as P504-ND
• remove "gnds" from power header - see page 9 of Accelnet for grounding method

• RS232 connector over board edge by ~0.1"
• termblk header obscures 1/2 the lower line of text labels "CHS COM HV+...."

• DB25 plate mounting holes
• smaller copley connector is 22 pins - not 24pins specified in SCH and PCB

• zener diode across caps for shunting brakeing current
• swap RS-232 signals on RJ11
• add resistor across REF+- inputs

History

• Board submitted to AP-Circuits 6-8-05
• Ser #1,#2 built 6-10-05

• cut RxD, TxD traces on #1,#2 from RJ-11 ie swapped signals
