Prerequisites; Pc Modes; Active Mode; Passive Mode - Emerson SC2MDST User Manual

Prerequisites

1. Obtain and install the applications, drivers and files of the
cryptographic software (CSP) which corresponds to your
selected smart card vendor.
2. Obtain a smart card from your selected smart card vendor.
3. Verify that your smart card setup works correctly on each
PC using a standard smart card reader prior to connecting
the MDR.

PC Modes

The MDR has a built-in association mechanism which allows the
smart card to be concurrently mapped to multiple PCs. PC Modes
determines which of the associated PCs is set as Active, while others
are set as Passive. An Active PC has full (read/write) access to the
smart card which is inserted into the MDR. A Passive PC recognizes
the smart card but has no access to it until it is made Active. At any
given time only one PC can be set as Active.

Active Mode


The smart card is inserted into the MDR.

The PC Association LED is ON.

The PC Number LED is ON.

The MDR appears under the computer's operating system
device manager as a smart card reader.

The computer's OS and applications have full (read/write)
access to the smart card.

Passive Mode

15
Section 4 - Operation

The smart card is inserted into the MDR.

The PC Association LED is ON.

The PC Number LED is OFF.

The MDR appears under the computer's operating system
device manager as a smart card reader.

The computer's OS and applications have NO access to the
smart card..

MDR Operational Modes

Operational Mode settings determines how Active/Passive PC
Modes are set. For example, when the MDR Operational Mode is
set to Manual, the user has to manually press the PC Number
Button corresponding to the PC that requires access to the smart
card.
When the MDR Operational Mode is set to dynamic, auto-
association methods are used to determine which PC will be set as
Active. For example, when the MDR operational mode is set to
Activity-Detection Auto Association, the MDR will automatically
actively associate itself to the computer which requires smart card
access based on an activity detection algorithm.
To preset which MDR Operational Mode is in use (Manual /
Auto...etc), a hardware dual in-line package (DIP) MDR has to be
configured. See the MDR configuration settings in Table 01, column
DIP MDR.
