Applications

Control Module Inc (CMI) has manufactured time and attendance clock systems used in commercial and industrial workplaces for employee time tracking. The 2040-002 Comm Snap Module is an add-on accessory for the CMI legacy time clock product line, enabling the clock to communicate over RS-232 or RS-485 serial connections. RS-485 in particular supports multi-drop wiring, making it well suited for environments where several time clocks need to report back to a central data collection point over a single cable run. These communication modules were commonly used in manufacturing plants, warehouses, and other facilities running CMI time and attendance systems that required centralized payroll data collection. This type of snap-on modular design was a cost-effective way for operators to add or upgrade communication options on existing CMI clock installations without replacing the base unit. Facilities maintaining legacy CMI time clock infrastructure will find this module a direct replacement part for restoring or expanding serial connectivity.
