Revision as of 01:31, 11 June 2005
Breakout board for Accelnet Micro Module
- for Copley Controls Corp models : ACK-055-06, or ACK-090-04
Contents
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
Designs
Reference
Errors
- Need to switch RxD and TxD on the RJ11 connector. Do this by cutting traces and adding jumper wires.
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 the 24 pins that I have
- zener diode across caps for shunting breaking current
- swap RS232 on RJ11
- 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
