Installing a 2500
Firmware Update
The 2500 firmware will be updated periodically to add new operating
features. The update replaces the EPROM in location
U15
and/or
U43
on
the handler controller board.
CAUTION: To avoid possible damage to the system components, this
procedure should be performed only by a qualified service
technician. Observe all antistatic precautions while
performing this operation.
Follow these steps to install a firmware update to the 2500. To reduce or
prevent possible damage to these static-sensitive devices from ESD, wear
your antistatic wrist strap when performing this procedure.
1. Turn off the 2500 and remove the power cord.
2. Remove all devices from the tracks and all tubes from the tube
holders.
3. Unscrew the two corner screws that hold the main plate to the 2500’s
base.
4. Lift the main plate to expose the 2500’s interior, and remove the
internal device shield.
WARNING:To prevent the hood or main plate from accidentally
falling shut, be careful not to jar the 2500 when they are
raised.
5. Locate the U15/U43 EPROM on the handler controller board (refer to
the controller board layout in Figure 2-20 and Appendix C).
6. Use an IC remover tool to carefully remove the current DIP firmware
device from its socket.
7. Install the new firmware device in the socket, being careful not to
bend any of the device leads. Make sure that pin 1 is properly
oriented.
