6. UPDATING SOFTWARE

Every new SCR® Recycler supplied from CPI© contains “blank” (or vanilla) software.
As such, it will not function in normal operational conditions. Therefore, all software
for the SCR device (application code and required variant/billset) must to be
programmed prior to use. There are three methods in which to perform software
updates for SCR:

1. Cashflow® STS software tool

2. Field programming module called PPM Advance™

3. Protocol specific commands via software packages trough Serial (RS232) or
USB (optional) interface

Please note that an un-programmed unit will not communicate via serial

interface. The MMI panel will illuminate all 3 LEDs and flash simultaneously.

6.1 USING CASHFLOW STS TOOL FOR SOFTWARE UPDATE

Cashflow® STS support tool version 7.10 or higher is required for updating SCR
software. This tool also requires a license key, which can be from the CPI Technical
Support team, upon request. More information about the Cashflow® STS installation
can be found in STS User Manual.

Ensure that the correct USB drivers are installed for the SCR prior to use. Connect
to the SCR via the front USB port on the SCN acceptor head. Successful connection
will reveal a highlighted “Read” button and the SCR device Serial Number will
populate on the lower portion of the window (Image 37)

6.2 USING PPM ADV ANCE FOR SOFTWARE UPDATE

The SCR software can also be updated using the PPM Advance™. The SCR
application firmware, variant and/or configuration file(s) can be loaded to the
handheld device and delivered remotely with the need for a PC. For a detailed
description on how to load the required files into PPM Advance™ memory, please
refer to the PPM Advance User Manual. This document can be requested by
contacting CPI Technical Support.

Before starting the software update procedure, ensure that the SCR unit is connected
via the front USB service port to using a standard USB A-to-B cable. When
navigating through the PPM Advance™ device screen, select “BA Update” menu and
“SC Recycler” submenu to select the software file(s) for update. Press (OK) button to
send the file(s) to the SCR.

The PPM Advance firmware version must be 1.03 or higher to function

with the SCR. If required, an update can be performed using Cashflow STS
version 7.10 or higher.

6.3 USING SERIAL PROTOCOL FOR SOFTWARE UPDATE

The SCR software can be updated via a special set of protocol commands, which
can be integrated into the host machine’s application. This method can be
accomplished by use of one of the existing API libraries or direct protocol integration.

For more information please refer to Protocol Integration Manual and Protocol
Specification which can be requested from the CPI Technical Support Team.
