FOR USE WITH THE CECB4

9 September, 2003

GENERAL

The modem must have been purchased from VENDAPIN L.L.C.  Next take the CD and the Zoltrix manual and put them in a safe place.  These items will not be used in the installation because they are only to be used in a normal install for applications under windows.  It is best to do a boot of Windows before running VendaCom to free up enough memory for it to run and to make sure the communications port is properly closed and not still open with some other application (such as a PDA or mouse).  To really make sure all is correct, reboot Windows as well.

The modems have been designed to work properly at either the CECB4 or (PC) host connection.  

[Please do not alter the modem string or change the internal 4 megabyte program.   Any change to the internal program will destroy the loaded software communications program]

DIRECT CONNECT TEST

The CECB4 must be adequately tested under the Direct Connect mode with VendaCom before attempting connecting with a modem.   A different cable is used for Direct Connect than for the Modem connection.  The DB9 connector hoods are marked either 'MODEM' for modem and 'VC' for direct connect.  Note that the telephone wire has either 4 or 2 wires for use with the Modem telephone connection.

Under the Communications window, set the correct license number (usually 123456) in your Vendapin CECB4 processor.  Set the Password (usually 0) and the NEW and OLD Access Codes (usually AAAAAAAA).  At the same time set the Modem Init. String to null [             ].   It may be of the form 'AT…' before clearing it.

Using the SETUP pull down window, make sure the Direct Connect Comm Port has the correct port assigned.  Note that the direct connect and modem ports can be the same since they are not used at the same time.

Now the CECB4 can be tested with VendaCom using a direct connect cable.  Transfer data in both directions using Direct Connect and the Board (transfers to the CECB4) and Monitor Icons.  Only after the Direct Connect testing is complete can the modem test be performed.

MODEM TEST

Using the SETUP pull down window, make sure the 'Host Modem Init.' string is set the 'AT&Y0'.  Check (mark) the box for  'Overwrite Dispenser Info.'  Set the telephone prefix to any codes needed, e.g. '9*1727' where '9' is for an outside line, '1' for long distance and area code of '727'.

In the Communications window set the Vend Device Phone number to a seven digit number.  Note that this is an extension of the prefix just entered in SETUP.

VendaCom is now ready for the modem testing.  Use the special modem connect cable and make sure the cables are securely tightened.  Make sure that the telephone cable plugged from the wall telephone jack to the 'Live jack' at the modem is four conductor cable.  The cable plugged into the CECB4 J1 jack is six data communications flat conductor cable. 

Please make sure the cable hood marked 'MODEM' is used at the modem DB9 connection.   The DB-9/RJ-12 connector is not the same as the DB-9/RJ-12 that is used for serial communications.  You will note the telephone DB-9/RJ-12 connector is a male connector whereas the serial communications DB-9/RJ-12 used for the VendaCom direct connect is a female connector.

Press the Icon Button Telephone at the top to do the modem connect and transfers.  If all goes well, down in the bottom left a series of messages will appear, such as:

'Dialing 8456992'

'Waiting for Connect'

'Setting Send Mode'       OR  'Setting Receive Mode'

'Blocks'  (counts rapidly 1 to 22)

CAUTIONS

If a message of the form "… out of Memory" should appear in Vendacom when opening a dispenser, exit Vendacom and reboot Windows.  Do not ever use the window 'Dispenser Modem' under the 'Setup' pull down window.
