SMSC EVK-2074/84 SOFTWARE OPERATION MANUAL Revision 1.1 (03-31-06)
CircLinkTM EVB Software Operation Manual
1 Overview
This manual explains how to install and operate the CircLink
TM EVB Software. This software is used
to control a TMC2084 IO Node from a TMC2074 Host Node. This software was written using Visual
Studio VC++ 6.0 and is intended to run on a PC with a Windows 2000 or Windows XP operating
system. This software does not use interrupt handling. Editing this software requires a Visual Studio
VC++ 6.0 development environment. Correct operation of this software requires a CircLink evaluation
environment consisting of the following:
îš„Exactly one host node, consisting of a PCM-2074 evaluation board with TMC2074 Dual Mode
CircLink Controller installed.
îš„At least one IO node, consisting of an EVB-2084 evaluation board with TMC2084 IO Node CircLink
Controller installed. The CircLinkTM EVB Software comes configured for two IO nodes.
This application does not access the PCM-2074 directly, but indirectly through a device driver. For
instructions on installation of this device driver, refer to Chapter 4.

SOFTWARE OPERATION MANUAL
2 Operating Instructions
Operating instructions for the CircLinkTM EVB Software are described below. The screenshots are from
Windows 2000; however, they apply to Windows XP as well.
2.1 Starting the CircLinkTM EVB Software
The CircLinkTM EVB Software is started by invoking EcTest.exe. The screen shown in Figure 2.1 is
displayed, showing that the CircLinkTM EVB Software has started and is in the idle/configuration state.
This screen is the Main Screen for the CircLinkTM EVB Software. From this screen, the host and IO
nodes can be configured, along with CircLinkTM EVB Software operational parameters.
The CircLinkTM EVB Software is designed to be used with one PCM-2074 Host Node and a maximum
of 14 EVB-2084 IO Nodes. The table below shows allowed values for various configuration parameters
for the host and IO Nodes. Note that for some parameters, the PCM-2074 has possible values that
are not allowed when it is used with EVB-2084 devices.

Table 2.1 Configuration Settings for CircLink Nodes
NO PARAMETER ALLOWED SETTINGS NOTES
1 Node ID 1-15 (16-31 not allowed) Each node must have a unique Node ID
2 Max ID 1-15 (16-31 not allowed) Must be the same for all nodes.
3 Clock Master ID 1-15 (16-31 not allowed) Typically is the host node ID
4 Page Size 64 or 128 (32 and 256 not allowed) Must be the same for all nodes.
5 Speed 312.5 Kbps to 5Mbps Must be the same for all nodes
