INTRODUCTION
This document describes how to factory field upgrade the CK721-A controller firmware to
Release 3.0. This is the only supported method for upgrading CK721-A controllers in the
field when a P2000 host update has failed and the controller constantly reboots (the
controller does not come back online with the host). For standard CK721-A firmware
upgrade procedures, refer to the CK721-A Version 3.0 Software Release Notes. The upgrade
method described in this document does not require the host.
SYSTEM REQUIREMENTS
The following hardware and software are required to factory field upgrade the CK721-A
firmware:
PC running Microsoft® Windows® XP Professional or higher, or Windows 2000
Professional
NOTE
You will be required to change various Windows settings on this PC. To
minimize any future issues you may encounter as a result of these
changes, we recommend using a substitute computer (i.e. not the PC you
use day-to-day).
RS232 Null Modem Cable (DB9F/F) – Black Box EYN257T-0015-FF or
equivalent
10/100Base-T CAT5 Ethernet Cross-over Cable (or a standard CAT5
straight-through cable if connecting to a hub/switch) – Black Box EVCRB82-0020
or equivalent

PC TO CK721-A CONTROLLER CONNECTIONS
To connect the PC to the CK721-A controller:
1. Connect the RS232 Null Modem Cable to the PC’s COM 1 or COM 2 port
(see Figure 1). Connect the other end of the cable to the CK721-A’s
RS232C A port.
2. Connect the cross-over Ethernet cable to the PC’s network port. Connect the
other end of the cable to the CK721-A’s Ethernet port. (Use a cross-over
Ethernet cable to connect the PC directly to the CK721-A. Use
straight-through Ethernet cables to connect to the CK721-A via a switch or
hub.)

PC CONFIGURATION
Once you have properly connected the PC to the CK721-A controller, you are ready to
configure the PC. Configuring the PC consists of the following steps:
Copying and running the CK721-A Version 3.0 self-extracting archive file (see
page 5)
Verifying file and printer sharing for Microsoft networks is enabled
Changing the computer’s IP address (see page 5)
IMPORTANT
If firewall software is installed on your computer, you must disable it before
proceeding with the firmware upgrade.
NOTE
Configuring the PC takes approximately 2 minutes and must only be
performed once. Once the PC has been configured, installing the CK721-A
firmware takes approximately 15 minutes per controller.
IMPORTANT
Before changing the IP address settings of your PC, write down the current
settings (see the following table). This enables you to re-configure the PC
with the original settings once you have finished upgrading the CK721-A
controller(s). Failure to revert to the original settings may result in PC
network issues or other problems related to the configuration changes.
The following table provides a quick reference of the required PC configuration changes:
PC Setting Current Setting Change to . . .
File and Printer Sharing for
Microsoft Networks
Enabled
IP Address 192.168.2.1
Subnet Mask 255.255.255.0
NOTE
Windows XP Professional with Service Pack 2 was used in the
development of these instructions. Older versions of Windows XP
Professional will differ.
