Statement of Work Use existing autonomous controls of
chargers Implement optimized charge profiles Implement a GUI IAW previous profiles Charging technician to monitor, but not
expected to interfere with the charge

What We Have Learned RS 232/485 Previous Attempts Board Operations / Capabilities SCPI (Standard Commands for Programmable
Instruments) Schematic

Serial Interface Card Layout
No GPIB Header PWR Supply
J4: RS- 232/485
Support
For GPIB

What We Have Accomplished
Purchased a serial communications board produced by MOXA
Determined the required connections to the charger’s interface card
Connected to an individual interface card that is used inside the chargers
Received a positive communications response
RS-485 =>
GND P5 to J4P7
Data- P4 to J4P5Data+ P3 to J4P4
7
Our Plan Communicate with the chargers using the
RS 485 or RS 232 ports on the ICS 4861 board currently installed within the chargers
Connect the ICS 4861 boards to the PC using a Moxa CP-118EL serial board
Create a simple GUI to convert the SCPI commands programmed into ICS 4861 board into an easily used touch screen program

Specifications Able to control chargers from single work
station Control includes (for two chargers):
Remote charger startup and shutdown Query and display:
output current/voltage Front panel indications
Ability to change output levels

Timeline See Gantt Chart
Future Works (Spring 2010)
Code program with the ability to:1. Configure 4861 board with network
address. (Used for RS 485 multi-drop)2. Manually send SPCI commands3. Change voltage/voltage trigger4. Change current/current trigger5. Stop charger.6. Query voltage and current from charger.
