FIRMWARE RETROFIT KIT

1. DESCRIPTION

Kepco KIT 219-0529 contains two identical PROMs used to upgrade the firmware for the GPIB interface of two
BOP 1000W power supplies. The upgraded GPIB interface firmware is more reliable in multiple unit operation,
streamlines operation, adds recording of errors and provides for recovery of all errors reported by the GPIB.

This KIT applies only to

• Models BOP 50-20MG, BOP 72-14MG and BOP 100-10MG, all revisions

• Models BOP 10-75-MG, BOP 20-50MG and BOP 36-28MG, revision 5 and higher

• Models BOP 10-75-MG-26566, BOP 20-50MG-26828 and BOP 36-28MG-26567

NOTE: The 10V, 20V and 36V models below revision 5 which are NOT marked with 26566, 26828, 26567,

respectively, must first be upgraded using KIT 219-0491 which must be ordered separately.

When the upgrade is complete, a five digit number is added to the Model number of the modified unit to identify the
upgrade(s) installed.
