ADR SD/RS232 Module Operating Manual 1

OVERVIEW

The Peek ADR-2000 SD/RS232 Module is designed to fit into Peek’s ADR-2000 Plus automatic data recorders, providing a new way to store, retrieve and transport traffic data. It allows an ADR data recorder operator to use standard SD (‘secure digital’) or SDHC (‘secure digital – high capacity’) memory cards. Cards that meet the SD standard use the logo shown in. Cards that meet the SD-HC standard, typically those with more than 2GB of capacity, use the logo shown in. The ADR-2000 SD/RS232 Module can use either type of card. The drive is able to access up to 4GB of storage space on any size SDHC card. Throughout the rest of this document, the use of the term ‘SD’ memory card will refer to both standard and high-capacity cards.

SD memory card technology used by the ADR-2000 SD/RS232 Module, offers high-performance in a reliable, easy to use format. The advantages of SD cards over older memory storage methods include:

Write protection for your data

.Ease of availability

Wider range of storage capacities (much higher than PCMCIA)

Lower in cost per kilobyte than any other type of memory

Easy to use "push-push" socket makes inserting and removing media simple

Portability and compact size

Interoperable SD cards offer flexibility in transferring data to other devices

Can be read from a standard card reader attached to a PC / laptop

Allows studies to be created that generate large sized data files (for example, you can use smaller recording intervals on binned files and perform PVR studies simultaneously with a binned study).

System Requirements The ADR-2000 SD/RS232 Module is installed internally in the ADR-2000 Plus. The spring-loaded SD memory card slot is accessible through a splash resistant cover on the front panel of the ADR-2000 Plus unit.

The firmware loaded into the ADR unit must be at version 6.12 or higher. This allows the host ADR to recognize the SD Drive, and allows an operator to assign file storage to SD cards that have been inserted into the unit.

Figure 4 shows the front view and side view of the ADR-2000 SD/RS232 Module in place, as the left-most drive installed in the backplane of the ADR unit. The SD card slot is accessible through the front panel of the ADR-2000.

ADR SD Drive Application The ADR-2000 Plus’s ADR-2000 SD/RS232 Module is installed internally, with the SD card slot accessible through the splash resistant drive cover on the front operating panel of the ADR unit, as shown in Figure 6.

The ADR SD Drive offers a variety of data transmission, storage, and retrieval options. An ADR2000 Plus with the ADRSD/RS232 module installed allows for data retrieval in three (3) ways:

Downloaded via central communications (i.e. TOPS or IQ Data)

Downloaded via Local Serial connection

Downloaded by physically removing the SD card and attaching to a PC using a standard SD card reader

Communication Ports An ADR 2000 Plus with the ADR SD/RS232 module installed has 2 serial communications ports:

COM 1 (Standard with the ADR 2000 Plus) provides:

Serial communications

Selectable baud rates between 300 and 19,200 bps

Provision for charging the ADR2000 Plus unit

COM 3 (SD/RS232):

Connection via a UL and CSA approved female socket

Supports TxD, RxD, and DTR data transmission at rates of up to 115,200 bps

Note Although the Although COM 3 port uses the same connector, it does not support charging, or the CTS signal

Upgrade an Existing ADR-2000 Plus The new ADR-2000 SD/RS232 Module can be installed in an existing ADR-2000 Plus unit. However, this is not a user-upgrade. The ADR-2000 Plus unit must be returned to the factory for service by our trained technicians. Contact the Peek Traffic Corporation Customer Service Center for information on ADR-2000 SD/RS232 Module upgrades for existing ADR-2000 Plus units.


Using the ADR SD Drive

The function of the ADR-2000 SD/RS232 Module is to allow an ADR operator to use SD memory cards as a memory storage location for files and data, to allow data to be retrieved from field locations, and to allow files to be transferred between ADR units. The SD card functions as a removable hard drive.

Selecting SD Memory Cards The ADR-2000 SD/RS232 Module is compatible with all

SD or SD-HC memory cards. This includes memory cards available from a variety of retail outlets, such as drug stores or electronics retailers, including higher capacity cards of greater. However, the FAT16 filing system used when the ADR-2000 SD/RS232 Module formats your card will only be able to address the first 4GB of the SD card’s capacity.

Figure 5 – A Typical SD Card

Another consideration when selecting an SD memory card is response time. There are differences in the speeds at which an SD card reads and writes data, which can impact how quickly they read back data for transmission. Generally all SD cards, regardless of the make or model, are sufficiently responsive to support the writing requirements of an ADR unit. It should be mentioned, however, that the SD card units sold by Peek Traffic have been specifically selected for their quick response times and their ability to handle the harsh environmental conditions to which a typical roadside traffic counter/classifier is exposed. The specifications for the Peek cards are listed on page 10.


Inserting an SD Card in the ADR SD Drive The ADR-2000 SD/RS232 Module’s card slot is a spring loaded mechanism. To insert a card, press firmly until the card clicks into place. The angled notch in the corner of the card should be toward the bottom of the ADR SD drive, and the metal connection pads should be facing to the left. Make sure that the Write switch on the SD card is unlocked.

A card can be inserted into the ADR SD Drive at any time, whether or not the ADR is powered.

Figure 6 – Inserting an SD Card into the ADR-2000 SD/RS232 Module’s SD Drive

Formatting an SD Card Formatting an SD Card is performed exactly the same way it is for any other memory location attached to an ADR. Insert the SD card into the slot, activate the ADR interface, and navigate to the Format Media screen. The SD card can be selected by using the left or right arrow buttons, at which point you will see the drive shown like this:

SOURCE MEDIA SD CARD 08 FREE MEMORY 01948Mb <>CHG; ENTER SELECTS

Figure 7 – Navigate to the Format Media screen on the ADR

It is strongly recommended that you format your SD cards to be used with the ADR within the ADR unit itself before attempting to use it for data storage. This is true even if it came preformatted or you formatted it from a PC prior to installing it in the ADR unit. The reason for this is file capacity. An SD card that was formatted on a PC may only allow 500 individual files to be stored on the card, while the formatting done within the ADR guarantees that the SD card will accept up to 7000 files at once. (Complex, long duration studies can create large numbers of data files.)


Removing an SD Card from the ADR-2000 Plus SD Drive It is important that you follow the steps below for removing an SD card from the ADR-2000 SD/RS232 Module’s SD card slot. This will eliminate the possibility of interrupting the ADR as it writes data to the SD card. The data transfer to the SD media must be complete and the card closed before it is removed. To remove the SD card, follow these steps:

1. Open the ADR-2000 Plus interface, and press ESC to enter the menu system.

2. Use up and down arrow buttons to navigate to QUIT REC. The selection screen will appear, as shown in Figure 8. Press the ENTER key to select QUIT REC.

[1] CHECK QUIT REC* [4] CONFIGURE [5] FILES

Figure 8 – Navigate to the Quit Recording screen on the ADR-2000

3. Display will show QUIT REC, ARE YOU SURE?, NO. Use the left or right arrow buttons to change to YES, as shown in Figure 9. Then Press the ENTER key to confirm. The current recording file will be closed.

QUIT REC ARE YOU SURE? YES <> CHG: ENTER SELECTS

Figure 9 – Quit Recording Confirmation screen

The display will reflect that the system is “IDLE”. You may now remove the SD Card. The correct method to remove the SD card is to firmly press the card into the slot and release it. You should hear a click (indicating that the card is disengaged from the spring clip) and the card should pop partially out of the slot.


Setting the SD Card as an ADR File Location To use the SD card as a file/data storage location, you will need to tell the ADR how to use it. This means assigning files types and percentages to the new memory location provided by the SD card.

1. Insert an SD card into the ADR-2000’s SD card slot.

2. Open the ADR-2000 interface and press ESC to enter the menus.

3. Go into the Configure menu (Keyboard button ‘4’ or scroll and ENTER.)

4. Scroll down and select File Storage. You will see the File Storage selection window, as shown in Figure 10.

FILE PRIMARY MEDIA BIN CPU MODULE 00< PVR CPU MODULE 00 SETUP CPU MODULE 00

Figure 10 – Setting the SD card as a File Storage location

5. Move the cursor down to the type of file you want to change to the use of a SD Card. Navigate by using the ENTER key. To select the Primary media for that file type, use the left (F3) or right (F4) arrow keys. This allows the primary media to be changed between CPU MODULE 00 and SD CARD 08. Once SD CARD 08 has been selected, press the ENTER key to move to the screen shown in Figure 11.

FILE MEDIA % BIN 00 100 PVR 08 100 STP 00 100

6. Allocate the percentage of memory to be written to the primary media selected in the previous step by using the numbered keys for your selection and pressing the ENTER key to move to the next file type. Once percentages have been entered for each file type, the ENTER key will exit to the previous FILE STORAGE screen.

7. You may now define a study. Any data generated of the file type selected, will be stored on the SD Card.

Figure 11 – Defining where files are stored


Transferring Files from the SD/RS232 To retrieve the data off of an SD card, there are two possible options:

Retrieve the Data Remotely This is done in exactly the same manner currently used, except you select the SD card as the source of the data files. Note that the speed of the data transfer may become an issue, since some of the data files can potentially become extremely large.

An ADR 2000 Plus with an ADR SD Drive has 2 COM ports:

COM1 has a baud rate of 19,200. The unit may be charged through this port.

COM 3 supports data transfer speeds of up to 115,200 bps and should be used for data retrieval.

Retrieve the Data Physically

The other method to retrieve data from the ADR is to physically travel to the site and remove the SD card from the ADR SD Drive. The Data files on the SD card can then be read by any standard SD Card reader, and the files can be transferred directly to the PC.

Note Follow the correct procedure described page 6, to remove the SD card from the ADR unit without causing data loss,


ADDITIONAL GUIDANCE

For more guidance on the configuration and use of the ADR-2000 SD/RS232 Module, refer to the following information, documents and contacts.

Troubleshooting

These are some suggested steps to follow if your ADR SD Drive is not working as it should. It’s best to work your way from the top to bottom of the table until you find the problem.

Table 1 – Troubleshooting checklist

Symptom Possible Causes/Resolutions Make sure you have a version of the ADR firmware that supports the ADR SD Drive. The firmware should be at version 6.12 or higher. Verify that the write-lock mechanism on the side of the SD card is not in the ‘locked’ position. Try a different SD card in the slot and see if a capacity number shows up in the ADR interface. If a card does not work, it may need to be formatted. This can be done using the ADR interface, under the FILES menu.

SD Drive doesn’t show up as an option in the ADR screen interface. The check equipment screen shows that the SD Drive is in place, but the card capacity is shown as ‘?’

If you cannot get an SD card to be recognized in the slot, even though the drive itself is recognized by the ADR interface, you may have a faulty drive. Arrange to return the ADR-2000 Plus unit for repair or replacement. The RMA process is described on the Counter/Classifier Support page on the Peek Traffic website: www.peektraffic.com/ptdataspt.htm
