The 4XB Programmer Droid, a creation of Cybot Galactica, was engineered with the purpose of supervising and programming other droids. To accomplish this, 4XB units employed intricate electronic sound sequences to program other droids, which necessitated the inclusion of a CG1XB Translator Module in those droids. Frequently, a 4XB unit would be responsible for the routine management of automated mines, manufacturing plants, correctional facilities, and organizations dedicated to upholding the law. The prison settlement of Balis-Baurgh was managed by a 4XB unit.
