3. Detailed operation steps

Step 1. Initial Setup – Encrypt Card and Controller(AR-837-W)

Initial setup includes AR-837-W setting and encrypting both hardware and cards. That way, only encrypted cards can be read on the deduction device for consumption purpose and only encrypted devices could have deduction feature.

To implement below step, please prepare Mifare SOR Programming Kit, hardware, and tags ready

Before starting the operating steps, please prepare:
1. SOYAL Software--Mifare Key ►Introduction and Download of MIFARE Key Software
2. MIFARE SOR Encryption Card and Device Editor ► AR-725-P Product Introduction
3. Point Deduction Device (Controller) ►AR-837-W Product Introduction
(4) Mifare Card ► Card Product Introduction

1-1 SOR Authorization Card Setting

Using authorization card to save password (Key A/ Key B) and to set the permissions to strengthen the password the confidentiality. Authorization cards is a very important, please keep these cards in a safe place.

KeyA KeyB :

Key A / Key B is two 12 16 Hex value and Config Trailer composed.

Key A=12 16 Hex value, 0-9 and A-F
Key B=12 16 Hex value, 0-9 and A-F
There ard two kind Config Trailer: A: Decrement, A:Increment (Default) and A: Decrement, B: Increment.
A: Decrement, A:Increment (Default): Read and write data before must be checked SOR card and the SOR controller the key A.
A: Decrement, B: Increment: Read data before must be checked SOR card and the SOR controller the key A. Write data before must be checked SOR card and the SOR controller the key B.

※ Note : Card and controller Data transfer required check Key A /Key B and distribution Code.

STEP 12 : Selection 16 in "Source Block" field.

STEP 13 : Selection 00 in "Device TMP Buffer" field.

STEP 14 : Press "Execute" button.

STEP 15 : If status bar show "Copy Key from SIM(16) to Template Buffer(00) OK !" indicates UMI card block 16 has been successfully copied to Template Buffer 00.

STEP 16 : Selection 17 in "Source Block" field.

STEP 17 : Selection 01 in "Device TMP Buffer" field.

STEP 18 : Press "Execute" button.

STEP 19 : If status bar show "Copy Key from SIM(16) to Template Buffer(00) OK !" indicates UMI card block 17

Now your card has become SOR-LAM Card (encrypted)

Step 2. Add Value to the SOR cards

After the initial setup is finished, all of the encryption has been done and the steps left is to add value (points) for LAM-SOR card. One point is equivalent to one minute of electricity usage, that means if you add 100 points and only charge for one hour (60minutes), SOR tag still have 40 minutes left for next usage.

2-1 Launch SOR SIM Card

This step is required to obtain KeyA and KeyB of SIM Card for authorization before moving on Step 2-2

STEP 1 : Ending all SOYAL software and plug in AR-725-P's USB to PC open MIFAREKEY software.

STEP 2 : Selection COM Port.

STEP 3 : Selection controller item No. For example: AR-725-P.

For all Enterprise E series controller reader / Home H series controller reader, please select the model name of AR721x/AR881E.
For all Wiegand reader, please select the model name of AR737P/U

STEP 4 : Click "Connect" button to connect.

STEP 5 : If status bar show "Decice Login OK! " indicates successful connection

STEP 6 : Place SIM card to the AR-725-P the MIFARE software will show SIM icon.

STEP 7 : Selection "Store in SIM/CIM/UIM Data Block" write data to SIM/CIM/UIM block.

STEP 8 : Input the desired Key A / Key B (Key A=12 16 Hex value, Key B=12 16 Hex value).

STEP 9 : Selection A: Decrement, B: Increment in "Config [Trailer]".

STEP 10 : Selection 16 in "Dest" field ( Save Key A/ Key B to 16th Block).

STEP 11 : Press "Execute" button.

STEP 12 : If status bar show "Write KeyAB to SIM/CIM/UIM OK! " indicates that the data successfully written SIM card.

STEP 13 : Selection Config [Trailer] "Default(FF078069)" to set another Key A / Key B.

STEP 14 : Selection 17 in "Dest" field ( Save Key A/ Key B to 17th Block).

STEP 15 : Press "Execute" button.

STEP 16 : If status bar show "Write KeyAB to SIM/CIM/UIM OK! " indicates that the data successfully written SIM card.

2-2 Add Value to SOR-LAM Card

The card point ratio must be an integer and the total value must be less than 32,767.

STEP 1 : After putting the SOR-LAM Card, current balance will show on Value Block section. Enter final balance.

STEP 2 : After completing the settings, click the [Launch+++] button to update the remaining balance of the points on the card.

Step 3. Consumption & Balance Deduction

When you insert a card to AR-837-W it will show several information on the LCD such as

Note:

To deduct the balance press 2 digit points and end with #

Example: deduction for 15 minutes enter --> 15#

When you inserted the card, it will show current balance or else enter 00# to check card balance

3-1 Unable to charge when card balance is insufficient

When you card has insufficient, after entering how many minutes you want to charge your vehicle, the LCD will show insufficient balance on the LCD. At the same time 701ClientSQL will also show the correspondent event log.

Display on 701ClientSQL Event log

3-2 Successfully charging when balance is sufficient

3-2-1 Start charging

When you card has sufficient balance, after entering how many minutes you want to charge your vehicle, the LCD will show Balance Remaining and Current Consumption

Timer will also show the countdown on how many minutes left charger will keep on charging (relay ON). At the same time you will see that charger is working.

Example: A card that has a balance of 1600 Points available for deduction, enter 01# to deduct 1 point=1minute (example using smartphone charging)

Display on AR-837-W LCD screen :

B= Balance remaining for next deduction (916 Points)

P= Point deduction for current deduction

Timer: show how much time (hour/min/sec) left for until charging is finished

Display on 701ClientSQL Event log

3-2-2 While charging

After finished deducting the balance on the card, user can take out the card and controller will keep on charging and counting the time remaining until charging is finished.

3-2-3 Finished charging

After time out, controller will automatically stop charging and at the same time 701ClientSQL will also show the charging has been finished (relay OFF)（relay OFF）

Display on 701ClientSQL Event log
