Gasboy SDI CAT Interface - Manual (Page 9)

2 SDI/Wayne CAT Interface SC II and CFN3
Gasboy CFN Series
Installation
Set the CAT address to match reader address, regardless of what the FIRST_ADDRESS
parameter is set to. CAT number 1 responds as reader number 1, number 2 as 2, etc.
If a Master Security Module is used, connect it to the Wayne 485 loop along with all the
CATs. Connect this to the SDI box DB25 connector using the supplied cable. You must use the
Master Security Module if you need data encryption for debit cards.
Connect the Gasboy RS485 loop into one of the phone-type jacks in the SDI box. Other
Gasboy devices, including additional SDI boxes can be connected to the same Gasboy loop. The
Gasboy loop is the only connection that can have more than one SDI.
There can be only 1 SDI per DB25 loop. A single SDI unit can handle up to 6 CATs and
one security module (if DES encryption is used). A second SDI box is needed to handle each
additional 6 CATs. If more than one SDI is used, a security module is also required for each
additional SDI.
The CAT display is 2x16, you will also need the Merit/CAT driver in the operating system.
Setup
In order to support the Wayne CAT interface, a version of the SDI driver which is a subset of the
actual driver in the Site Controller has been included. Use the commands ENABLE SDI,
DISABLE SDI, DOWNLOAD SDI, and SEND SDI.
TABLE.BIN
Set the number of SDIs to be polled by setting the number of SDIs in TABLE.BIN. For one SDI
you must leave at least 236 bytes of free space as reported by TABLE.BIN. For each additional
SDI you must leave 118 bytes more.
Application files
For each Wayne interface you need an application binary file and a parameter file. These are
stored in the root directory of the Site Controller. For a Site Controller II, the location would be
C:XBIN. For a CFN3 the location would be C:/SC3/XBIN.
Application Binary file
The application binary for SDI #1 will have an extension of ‘B01’. For example, CAT.B01 would
be a correct application binary name for SDI #1. There should only be one file that has B01 in the
directory. A second SDI (SDI#2) will have a binary file called CAT.B02. The files are identical
with two different names. If you need to create the CAT.B02 for the second SDI, copy the
CAT.B01 file and name it CAT.B02. Examples follow on how to copy and name your files.
