CASHTILL # 6/1

1. Reason for change.

        EDP has introduced a new type of intelligent cashdrawer which will only open in response to a given character string
        from the system.

2. Change

2.1. The new type of cash drawer is identified by a green led, an 8 pin miniature din connector and a low voltage connector
        for the external psu on the rear. The cash drawer will be connected to the aux port of a VDU, using a unique cable.

2.2 mec identity

        Standard rs232 cashdrawer cashbas-rs232-scd

        New intelligent rs232 cashdrawer cashbas-rs232(i)-scd

        (tech serv ref 97/21)

3. Mode of operation

3.1.The intelligent cashdrawer has an interface board, which is

        Programmable by means of 10 dip switches.

        The standard setting is:-

        9600 8 data 1 stop none parity.

        To operate the cashdrawer, two "ctrl-g" are required.

        The solenoid is fired using a timed pulse, which should eliminate solenoid burnout experienced in earlier types of
        cashdrawer.

3.2 The cashdrawer is supplied with a short data cable; 8 pin

        Miniture din to double 9 pin d type, one male one female. An interface cable of appropriate length will be required, to
        connect into the VDU aux port. This cable will be 9 pin d type male to 25 pin d type male with the specification shown
        below.

3.3. the external psu is mounted in the 13 amp plug.

        It is rated 12vdc at 500ma.

        The connector on the cash drawer has a negative centre.

4. Setting up.

4.1 ensure all power and data are disconnected before proceeding.

4.1 access the interface board by:-

4.2.1 inverting the cash drawer and removing 4 screws in the feet.

4.2.2 remove the bottom plate.

4.2.3 release the interface board bracket by removing the two screws at the rear, located approx 2" either side of the low
        voltage connector.

4.2.4 gently withdraw the interface board a little as the solenoid is still connected to it.

4.3. ensure the dip switches are set as listed below.

        1 = closed = on0 = open = off

        12345678910

        1110000000

        Switches 1-7 set the ascii character to ctrl-g

        Switch 8 sets the two character mode.

        Switches 9-10 set the baud rate to 9600

4.4. refit the interface board and replace the bottom plate.

        Connect the data cables and the psu.

4.5. set the VDU aux port up for serial printer 9600 8 1 n.

5.testing

5.1. configure the VDU to output ctrl-g ctrl-g to the aux port.

        Ensure the cash drawer opens.

5.1.1.

        For WYSE 55 VDU.

        In VDU set up select f5 ports

        Change host ports from modem to aux.

        Save and exit VDU set ups

        Anything typed on the keyboard will now come out of the aux port.

        On keyboard typectrl-g

        Ctrl-g

        The cashdrawer should open.

        After test enter VDU set up and select f5 ports

        Change host port back to modem from aux

        Save and exit VDU set up.

5.2. when functioning normally (see annex a) or when testing from

        The system, the ctrl-g ctrl-g must be preceded by the

        "printer on" signal and followed by the "printer off" signal.

5.2.1

        For WYSEyse 55 VDU, 2020 VDU, 4000 VDU.

        (for other VDU's you need to check the VDU operations manual to find the printer on and off sequence).

        On another VDU, other than the one connected to the VDU/cashdrawer under test; enter sysprog unilink the line to the
        unit under test converse this line

        Enterctrl-r- printer on

        Ctrl-g{ open cashdrawer

        Ctrl-g{ open cashdrawer

        Ctrl-t- printer off

        The cashdrawer should open.

        Unconverse the line and link it up again.

5.3.the green led should illuminate when the mains adapter is

        Powered. If the led does not illuminate, check the adapter and power cable.

5.4.the green led should flash momentarily when the interface receives data.

6.servicing

        Servicing in the field will be by whole unit replacement.

7.multi operation

        One cashdrawer can be operated from 2 VDU's using the icjd, intelligent cashdrawer junction device. The connections
        and cable specification are shown at annex b and annex c.
