KDE inc. EDM-4954设备无法获取IC卡ATR的技术求助

设备基础信息 #

• 型号：EDM-4954 VER: X1.01
• 类型：面向银行等企业客户的电动插拔式磁条卡+IC卡读写模块，带RS-232C接口
• 关联系列：EDM-4000、KDM-47XY、KDM-57XY

核心问题 #

设备上电后按INIT -> GET VERSION -> ENTRY -> STATUS REQUEST -> IC POWER ON流程发送指令，始终无法获取IC卡ATR，收到「IC CARD NO ATR」反馈，对应错误码为0X31 0X31 0X33。磁条卡功能正常，但需启用ICC EMV模式，尝试多款支付系统IC卡均出现相同问题。

待解疑问 #

1. 当前指令流程是否存在操作疏漏？
2. 该故障属于设备硬件问题还是配置缺失？
3. 如何正确启用设备的ICC EMV模式？
