1. 7 apc casi brawe Model 484A SerialPRO II Interface User s Guide Functional Description The 484A SerialPRO II Interface provides a dedicated easy to use and economical RS232 serial connection to APG cash drawers This interface will plug directly into the RS232 serial port of the host device computer terminal etc It has diagnostic lights to assist in installation and troubleshooting The unique design of this dedicated interface allows you to select 4 different levels of security for the drawer opening sequence significantly reducing the chance of unauthorized openings that result from noise associated with power up and power down of the system The DIP switches for selecting the opening sequence are conveniently located on the bottom of the cash drawer unit near the cable exit These DIP switches also allow for the selection of drawer status reporting location as well as other setup and diagnostic functions This interface is designed for standard RS232 implementations where DTR and RTS are held high while the port is open In most situations it is powered by the serial port eliminating the need for an external power supply An external power supply can be used in situations where DTR and RTS are not consistently held high as is the case with Windows NT The interface includes a cable for connection to the serial port As a standard product this cable is equipped with a 9 pin female DB9F connector and a 25 pin female DB25F to2. 9 pin male DB9M adapter cable I Configuration and Use This Guide assumes the user has some technical experience connecting computer peripherals 1 Verify DIP switch settings are applicable to the system The DIP switches see Figure 1 below on the electrical interface board are accessible from the bottom of the cash drawer unit Connect the cash drawer to the appropriate dedicated RS 232 serial COM port on the host device Open COM port and wait twelve seconds to charge drawer first time only before transmitting the opening sequence Open the cash drawer through the software or refer to step 5 below Transmit a BEL character from the host to open cash drawer See Section II and Section III for examples If cash drawer openings occur on power up down a higher level of noise immunity should be used This can be done by setting DIP switch 9 and switch 10 off switch 8 on and send any sequence of characters such as UU that produce a minimum of 8 pulse edges Refer to Chart 1 for more details DN Wily Switch Settings Description 1 Diagnostic Tool off Power Test disabled ON Power Test enabled Do not use until instructed 2 Extended Security ON RTS Disable set off RTS Disable released Do not use until instructed 3 4 Signal Source ON off PC operation enabled DB9 contact 3 DB25 contact 2 off ON Terminal operation enabled DB9 contact 2 DB25 contact3 5 CTS RTS Handshaking ON hands
