A-5DS was the first 5DS to be produced. Somehow, it ended being property of the Rebel Alliance, which modified it.
The Rebel command assigned A-5DS as an assistant to Ebranite operative Rith Tar'ak, who was to become a recruiter on her native Ebra. Tar'ak reprogrammed A-5DS so that it could help her to contact with Ebranite slaves on Grythsorin canyon.
