Working with the MDR

One completing the initial MDR configuration steps the MDR

is ready for use allowing simultaneous usage of a single

smartcard with multiple PCs.

Smartcard Removal Behavior

Removing the smartcard from the MDR immediately de-associates

the MDR from all coupled PCs. As a result, smartcard-aware

applications will notice the smartcard absence and respond

accordingly.

For example, a Windows PC that is configured to require

smartcards for user logon may be set to lock the user's desktop

once the smartcard is removed.

Re-associating the MDR after Smartcard

Removal

In order to continue using the smartcard (after it's been removed

from the MDR), the user has to insert the smartcard into the MDR

and complete steps 6-8 in order to re-associated the MDR with all

the corresponding PCs.

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 smartcard.

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),

there is a hardware dual in-line package (DIP) switch situated in the

underside of the base. See the switch configuration settings in Table

02, column DIP Switch.

Description

The user has to manually activate assosiation with the PCs for the first time, by

pressing channel buttons on the MDR. Once it is connected, it remains active and the

user can keep working with all the PCs.

The User will press the channel button each time for the MDR will associate itself with

the PC. Once the user presses another channel, the previous disconnects.

The User will press channel 1 only once and the MDR will associate itself to all the

connected PCs one by one automatically.

De-associating the MDR from a Specific PC

Long pressing a PC Number Button is the equivalent of removing

the smartcard only from the PC which corresponds to that button

without affecting other associated PCs. To re-associate that PC

with the MDR, press the PC Number Button to initialize the MDR

(as described in step 7).

The de-association option is useful in any case a user wants to de-

associate the MDR from a specific PC, without interfering with other

PCs which are associated with the MDR.

For example, when a user has to lock PC#1 by removing the

smartcard yet remain logged-on to PC#2, or when a certain PC is

not successfully associated with the MDR and the user wants to

re-associate it.

Reset

Hold one of the connected channel buttons for 7 seconds to reset

the device and its association with the PCs.

DIP Switch Configuration

1. To change the DIP switch settings, hold

the MDR with the underside facing you. In

this position, the DIP switch should be at

the upper right corner.

2. Gently remove the DIP switch cover.

3. The switch includes 8 slides numbered from

1 to 8, ordered from left to right.

4. When pulled down, slide status is OFF. When pulled up, slide status

is ON.

5. To activate an operation mode, pull down its corresponding slide.

6. Multiple slides can be turned OFF (pulled

down) at the same time.

7. Refer to Table 02 to adjust DIP switch settings with your work

scenario.
