The VPOS Model 316 External Trigger Modules are designed to provide RS232 serial interfacing to solenoid based cash drawers. This allows cash drawers, previously attached to POS printers and cash registers, to be connected directly to RS232 serial ports. A plug pack power supply is used to power the device. The interface module is designed to accept modular cash drawer connectors (RJ12). A string of characters sent to the RS232 port will trigger the cash drawer to open.
