6.1 iGEM Computer Board Replacement
When replacing the computer, see the IEC and NA software download sections of this manual
for procedures used to re-flash the pump code and load templates (NA). While the new computer
board may have pump code on-board, it may not be the latest code and, in some cases, new
pump code may not be compatible with the version of the dispenser template on your laptop.
Therefore, always use the latest version of pump code and the latest version of the dispenser
template (NA) to ensure compatibility. For NA regions, the latest versions can be downloaded
to your laptop from the Wayne ASONet.
1
Turn off power at the dispenser switch located to left of the iGEM board shown in 6.1. Also,
see WARNING statement on the previous page.
2
Disconnect J1 24VDC power cable to computer board.
NOTICE!
Bit Bus and Totalizer Cables
Interchanging the Bit Bus and EM Totalizers cables
will apply 24Vdc to the display board and likely re-
sult in damage to the display board, therefore:
3
Tag and disconnect the cables to J15 and J16. (Bit Bus A and Bit Bus B). +8Vdc.
4
Tag and disconnect the cables to J6 and J7. (E-M Tots Side A and Side B). +24Vdc.
5
Disconnect all other wiring to the board.
6
Disconnect cables from retainers and move all cables aside.
7
Remove (4) screws from corners of the board and pull board down under the bracket and
then down and out to remove.
Note!
For Helix dispensers, the iGEM board must have jumpers on each of the 2- pin connectors
SW13A to D, and SW14A to D. Eight jumpers (part number 4043601) are required. If these
jumpers are not in place, WIP communications through the Helix ISB board will be disrupted,
resulting in error code 59.
8
On the new iGEM replacement board, install jumpers as per the above Note. See iGEM board
photo in the Board Layout section for these jumper locations.
9
Install new board and reconnect cables — see note above.
10
Install new board using reverse procedure and reconnect all cables.
11
Re-flash the pump code and, for NA only, load the dispenser template as explained in the
Software Download sections of this manual.
