Upgrading the BIOS for the CRIND Logic Z180 PCA
Note: This Basic Input/Output System (BIOS) upgrade is needed for dual head card assembly
functionality. Contact the Gilbarco Technical Assistance Center (TAC) at 1-800-743-
7501 for the minimum version of CRIND BIOS required to operate the Dual Head Card
Reader.
Perform the following procedures to upgrade CRIND BIOS. This upgrade is initiated by
installing the U7 EPROM Integrated Circuit (IC), one per logic board, on CRIND logic
board(s) T17764-XX according to the following steps.
1 Locate the CRIND tray (Figure 26) inside the unit and pull the tray forward to expose the
CRIND Z180 Logic PCA (Figure 27).

Locate and remove existing EPROM IC at U7 (Figure 27) on CRIND logic board T17764-XX
using a grounded chip removal tool (Digikey K158-ND or equivalent, Figure 28).
A properly grounded ESD wrist strap must be worn during this procedure. Failure to use
electrostatic precautions may damage electronic components and void warranty.
