FREQUENTLY ASKED QUESTIONS
6) Can a PPM be used to update software for PROM CASHFLOW SC83 ® units?
No. A PPM can only be used to download software into Flash CASHFLOW SC83
®
units.
7) How can I tell the difference between a Flash and PROM CASHFLOW SC83
®
unit?
There are two ways to determine the difference:
1) The STS Program can be used to determine if a unit is a PROM or Flash.
2) You can remove the yellow cover on the acceptor. If a PROM is in the socket, it is a
PROM unit. If no PROM is present, it is a Flash unit (Refer to pages 19 thru 21 on PROM
units).
8) What are the MMI Diagnostic Error Codes (Green, Yellow and Red LED)?
Please refer to page 24 of this operation and maintenance manual for the MMI Diagnostic
Error Codes.
9) Can a CASHFLOW SC83
®
unit be calibrated in the Field?
A CASHFLOW SC83
®
unit can not be calibrated in the field. The CASHFLOW SC83
®
is
designed not to require field calibration. Calibration is only required after certain repairs
that are done to a CASHFLOW SC83
®
unit. Therefore, only an approved CASHFLOW
SC83
®
Service Center are trained to calibrate a CASHFLOW SC83
®
unit.
10) What are the differences among model #’s?
SC6602 is a Flash unit made to interface to IGT’s Netplex/SPC machines. It uses the IGT
ID024 interface and SPC USB interface.
SC6604 is a Flash unit made to interface to various machines. It uses MEI Opto Isolated
EBDS Interface.
SC6607 is a Flash unit made to interface to various machines. It uses MEI RS-232 EBDS
Interfaces.
11) What are the differences among interfaces?
MEI EBDS (Extended Bi-Directional Serial) Protocol is a proprietary MEI protocol
specification used to accomplish two-way serial communication between the bill acceptor
and a host machine. It is not used for interfacing to IGT machines. Open collector EBDS
uses opto isolated interface hardware. RS-232 EBDS uses RS-232 level interface hardware.
IGT Netplex (Serial) Protocol is proprietary IGT interface used to communicate
between the IGT host machine and the Bill Acceptor.
IGT SPC (USB) Protocol is proprietary IGT interface used to communicate between the
IGT host machine and the Bill Acceptor.
