ML1 Description

Usage – ML1 may be used as Magic Module data bus data logger, as a parallel printer interface to print the
logged messages as the messages are logged or after they have accumulated, and as an external modem interface to
control and reprogram the Magic Module System.

Printer Interface – A printer with a parallel port connection may be connected to J6, a 25 pin D connector.
The printer may be programmed to print each logged message as they are entered or print all the messages upon
command.

Modem Interface – J4, a 9 pin D connector is a serial, RS-232 port to connect to a Hayes compatible external
modem running at 28K baud or faster. The modem will answer only and will request a password. The password can
be in two levels: User and Installer Level. The passwords are set when programming the ML1 with the
Elk Product’s Magic Module Development Software using the Code Writer in the ML1 Mode.

Logging – Over 5000 data bus events may be logged into the ML1’s EEProm memory and later printed to the
parallel printer port or downloaded to a PC by way of the RS-485 data bus or an external modem connected to the
ML1’s serial modem port.

RS-485 Data Bus – The ML1 constantly monitors the RS-485 data bus to find any data packets that match
criteria that was programmed into the ML1 to log data when the criteria was matched. Excellent articles are available
from the National Semiconductor Website on the proper way to install the RS-485 Data bus:

http://www.national.com/an/AN/AN-979.pdf
http://www.national.com/an/AN/AN-1057.pdf

Programming – Programming is done through the Code Editor and Code Writer programs, and then loaded
into the ML1 through the Transmit program by way of the RS-485 data bus. The program is transferred from the PC to
the ML1 using the PC’s serial port and a RS-232 to an RS-485 converter box (ELK Part # MB485). These programs
are available in the Elk Product’s Magic Module Development Software.

Reset - In the event that a defective program has been loaded into the ML1 memory and the data bus can no
longer be accessed for reprogramming, the module’s program memory can be cleared and reset by shorting the solder
pads located at “TP1” and “TP2”, then powering up the module.

Elk Products, Inc Page 5 ML1 Instructions rev. 1.0 L493

ML1 Board Description

+12 VDC may be supplied at four (4) locations on the ML1 PC Board:

1. RS-485 Data Bus Terminal Strip terminals 1 and 4 (TB1 and TB2).

2. RS-485 Data Bus Jumper Header J1, Pins 1 and 4.

3. RS-485 Data Bus Jumper Header J2, Pins 1 and 4.

4. J3 Power Connector for plug in power supply, center pin is +12VDC.

Data Bus Terminal Description

1. +12VDC (TB1 Left) - Minimum 100 milliamps. Will vary according to equipment connected to the ML1.

2. Data Bus A (TB1 Right) - RS-485 data bus. All “A” terminals must be connected together when the data bus

is in use.

3. Data Bus B (TB2 Left) - RS-485 data bus. All “B” terminals must be connected together when the data bus is

in use.

4. Neg (TB2 Right) - Common ground or power supply negative terminal.

Elk Products, Inc Page 6 ML1 Instructions rev. 1.0 L493

Data Bus Address Jumpers

Each ML1 connected to the RS-485 data bus must have a unique address set on each ML1. This address is set on
the ML1 PC Board with five (5) jumpers. The address is set with a binary code; each jumper has a value as follows:

Jumper 1 (left jumper) = 1
Jumper 2 = 2
Jumper 3 = 4
Jumper 4 = 8
Jumper 5 = 16
By placing the appropriate jumper(s) in the upper or 1 position, the address setting may be set by adding up the

jumper values.

Example: Set data bus address 5.
Jumper 1 and jumper 3 will be placed into the “1” position. Add up the value: 1 + 4 = 5.

Set data bus address 17.
Jumper 1 and jumper 5 is placed into the “1” position. Add up the value: 1 + 16 = 17.

Note: After changing the data bus address jumper settings, the power must be turned
off and turned back on before the new jumper settings will take effect.

S1 – Print Button and S2 – Pause Button

Toggles the Parallel Printer On and Off. If the printer is enabled to print as you go, and the printer is turned off
as indicated by the Printer Status LED being Off, the print messages to the printer may be stopped by
pressing the Print or Pause Button. Press the Print or Pause Button again to enable the printer as indicated
by the Print Status LED being On. Note: Most printers have a built-in buffer so several lines of print data may
be buffered in the printer to be printed after the Print or Pause Button has been pressed.

S3 – Abort Button

When pressed, the ML1 will reset the location in the logged data to start printing at the beginning of the
logged data file in EEProm. When the Abort Button is pressed, the Print Status LED will go out. Press the
Print or Pause Button to get a complete print out of the logged data. Note: Printing the logged data does not
clear the logged data out of the EEProm memory.

Clear Logged Data

All the logged data that is stored in the EEProm may be cleared with the following procedure:

1. Press the Print or Pause Button. Note that the Print Status LED will go out.

2. Press at the same time: Pause, Print and Abort Buttons.

3. Within 1.5 seconds press the Abort Button.

4. In approximately 10 seconds the Print Status LED will come on indicating that the log EEProm
memory has been cleared.

The ML1 selections may be saved with the File/Save As MLP Settings File, and the ML1 selections may be
retrieved with the File/Open MLP Settings File in the Code Writer section.

Modem Setup Screen

User Password – Up to 16 characters may be entered for the normal user password. The user is normally the end

user or person that should not have access to all areas of the Magic Module System. The user password is sent when
logging into the ML1 from an external modem. An incorrect password will cause the modem to hang up. The default
password is User. This is case sensitive, so type the characters exactly as entered.

Superuser Password – Up to 16 characters may be entered for the Superuser password. The Superuser is normally
the installer or administrator. This user may access all levels of the data bus and Magic Module System. The
Superuser password is sent when logging into the ML1 from an external modem. An incorrect password will cause the
modem to hang up. The default password is Superuser. This is case sensitive, so type the characters exactly as
entered.

Modem Setup String – Up to 104 characters may be entered for the modem setup string. This is the command that
must be sent to a modem to initialize it for proper operation.

The default modem setup string show above is for a US Robotics Sportster 28.8K baud external modem. Other
manufacturers may require different setup strings. Consult the modem manufacturers technical documentation to see
what setup string is required for the modem that you are using.

To change the modem setup string, highlight the area to be changed and type the new setup string data.
As new setup strings are found, they will be posted on our website: www.elkproducts.com

5. The data will appear on the list.

To edit a selection on the list, double click the list line. The data will appear on the edit line.
To delete a list line item, highlight the list line and click the Delete Button.

Logging – Search Order

The order in which the ML1 searches the incoming data to be logged may be changed in order to give certain data
more priority on the selection process. Normally changing this selection process is not required.

In the example above the search order of the incoming data will be the Command, Type To, Address To, Type From,
and Address From. When the incoming data matches the Log Filter Data, the data is logged into the log EEProm.

Elk Products, Inc Page 12 ML1 Instructions rev. 1.0 L493

Logging – Log Filter

The Log Filter selects what data is to be logged and what Printer String is to be used when the data is printed. Print
Strings can be from 1 to 254, with Print String 255 reserved by the ML1.

Note: Before making Log Filter selections, make sure the Printer String that you want
to use for the print out of the logged data is available.

Setup the data bus data to log as follows:

1. Select the Command to key on from the Magic Module Data Bus Commands section. If the Command is
a wildcard or don’t care then select –none-.

2. In the same way if desired, select the Type To, Address To, Type From, and the Address From. If any of
these selections are a wildcard or don’t care then select –none-.

3. Select the Printer String that will be used to print the logged data.

4. Click the Insert Button to store the data into Log Filter List.

Double Clicking any selection in the Log Filter List will place the data on the Edit Line to be edited.

To delete an item in the Log Filter List, highlight the list line then click the Delete Button.

Selections may be made that will not ever allow logging by clicking the Never Log Click Button after the edit line
data has been entered.

Example: Log the Access Key data every time an access card is used.

1. From the Magic Module Data Bus Commands, the key data will be broadcast on the data bus with

Command 50 (32h). 50 is the decimal value, 32 hexadecimal is denoted as 32h.

2. Enter 50 (32h) into the Command drop down box.

3. Since we do not care about the Types and Addresses, leave those box set to –none-.

4. The Printer String that we will use is Print String 254 or FEh.

5. Click the Insert Button to store the new Log Filter Data in the Log Filter List.

When a Command 50 (32h) is sent on the data bus, the data packet will be logged into the EEProm memory in
the ML1.

Magic Module Data Bus Protocol

Example Data Bus Command: *<31:1240300?30= This command requests the status of relays on a Magic

Module.

The Magic Module Data Bus Protocol is made up of the following elements:

Byte 0 -

* - Start Character. The “*” character marks the start of the Magic Module Data Bus Packet.
< - Length Character. This is the length of the data packet. In this case the number of characters until the

Byte 1 -

first digit of the CRC is 12. The first byte “*” is not counted. See Single Byte Characters below for
further information.

Byte 2 - 3 - Type To Character. This is the device type that the data packet is being sent to. In this case a type 3 is a

MM443 Magic Module. See Single Byte Characters below for further information. This is available to
the MM443 Magic Module as variable TypeTo.

1 - Address To Character. This is the device address that the data packet is being sent to. In this case a

Byte 3 -

MM443 Magic Module set to an address of 1 on the data bus. See Single Byte Characters below for
further information.

Byte 4 - : - Type From Character. This is the device type that the data packet is coming from. In this case a “:” or

type 10 is a PC computer connected to the data bus. See Single Byte Characters below for further
information.

Byte 5 - 1 - Address From Character. This is the device address that the data packet is being sent from. In this case

a PC computer set to an address of 1 on the data bus. See Single Byte Characters below for further
information.

Byte 6 & 7 - 24 - Command. This is the data packet command expressed in hexadecimal. In this case Command 24

hex or 36 decimal is a Request For An Output Relay State. See Data Bus Commands and Two Byte
Data below. This is available to the MM443 Magic Module as variable RCMD.

Byte 8 & 9 -

Byte 10 & 11 -

Byte 12 to 15 -

Carriage Return and Line Feed (13 and 10 decimal value) always terminate a data packet.

Single Byte Characters

Single byte characters have a decimal value from 0 to 31. We use the ASCII character set to represent these
characters as follows:

0 = value 0
1 = value 1
2 = value 2
3 = value 3
4 = value 4
5 = value 5
6 = value 6
7 = value 7
8 = value 8
9 = value 9
: = value 10

03 – Data 1. This is the data 1 expressed in hexadecimal. In this case it is the address of the relay to

request the state of. Address 00 is relay 1 and address 03 is relay 4. See Two Byte Data below. This
is available to the MM443 Magic Module as variable RDAT1.

00 – Data 2. This is the data 2 expressed in hexadecimal. In this case it is not used and a value of 00

is transmitted. See Two Byte Data below. Additional data bytes may be included in other commands.
This is available to the MM443 Magic Module as variable RDAT2.

?30= – CRC Value. This is the Cyclic Redundancy Check Value. It is a 16 bit or 4 character value

that insures the data that has been transmitted is correct. Four Single Byte Characters are combined
together to form the CRC Value. The value of the length character will always point to the first character
of the CRC Value. In this case ?30= value is equal to 62221 decimal and F30D hexadecimal.

; = value 11
< = value 12
= = value 13
> = value 14
? = value 15
@ = value 16
A = value 17
B = value 18
C = value 19
D = value 20
E = value 21

F = value 22
G = value 23
H = value 24
I = value 25
J = value 26
K = value 27
L = value 28
M = value 29
N = value 30
O = value 31

Elk Products, Inc Page 16 ML1 Instructions rev. 1.0 L493

Two Byte Data

Command and data are expressed in two byte characters, which are a hexadecimal value. A hexadecimal character
can be from 0 to F (0123456789ABCDEF), which has a decimal value from 0 to 15. When the two hexadecimal
characters are combined together with a hexadecimal range from 00 to FF, they have a decimal value range from 000
to 255. All of the command and data are expressed in hexadecimal.

To convert a hexadecimal two byte value to decimal use the following procedure:

1. Multiply the left character value from the Hexadecimal Value Table below times 16.

2. Add the right character value from the Hexadecimal Value Table below to the value in step 1.

Hexadecimal Value Table
0 = value 0
1 = value 1
2 = value 2
3 = value 3
4 = value 4
5 = value 5

6 = value 6
7 = value 7
8 = value 8
9 = value 9
A = value 10
B = value 11

C = value 12
D = value 13
E = value 14

F = value 15

Printer String Commands

A Printer String is used to format the logged data into a readable string that makes sense when printed on the printer.
The ML1 stores the data in the EEProm in a different format from the way it was received from the Magic Module
System data bus.

Log Storage Locations

All logged data is stored as a single byte in the following logged data locations:

Log Storage Byte 9 = Type To, range 0 to 31 (1Fh)
Log Storage Byte 10 (Ah) = Address To, range 0 to 31 (1Fh)
Log Storage Byte 11 (Bh) = Type From, range 0 to 31 (1Fh)
Log Storage Byte 12 (Ch) = Address From, range 0 to 31 (1Fh)
Log Storage Byte 13 (Dh) = Command, range 0 to 255 (FFh)
Log Storage Byte 14 (Eh) = Data 0, range 0 to 255 (FFh)

…

Log Storage Byte 25 (19h) = Data 11, range 0 to 255 (FFh)

These values are used as the Offset value in the Printer String Format Codes.

Printer String Text

Text may be added at any location in the Printer String. The text may be individual ASCII characters separated by
commas 49, 50, 51, or strings of text delimited by brackets [and]. Example: [Relay is On] is printed by the printer as

Relay is On.

Format Control Codes

As data is logged into the ML1’s log memory, it is useful to retrieve the data and format it various ways before it is sent
to the printer. The Format Control Codes enables the programmer to specify how the data is formatted and sent to the
printer for any of the ML1’s logged data.

Format Code Definitions

¾ Offset – The log storage byte as explained in the Log Storage Locations above. Range 9 to 25.
¾ Value – The data value found at the Log Storage Location referenced by the value Offset. Range may be an

8 bit or 16 bit value. 0 to 255 or 0 to 65536

¾ Variable – A value that can be used for comparison or a fixed value. Range 0 to 255.
¾ Adder – A value that can be added to the logged data value. Range 0 to 255.

Elk Products, Inc Page 17 ML1 Instructions rev. 1.0 L493

¾ Count – A value that is used to count the number of cycles. Range 0 to 255.
¾ Shift – A value that denotes the number of times to right shift some value. Range 0 to 7.
¾ Mask – A value that is used to mask out bits of a value. The Mask value is Anded with some value. Range 0

to 255. Example: A value of 255 and a Mask value of 3 will equal 3.

¾ Compare – The compare string value that selects which type of compare string to use and which text message

to use. Easiest to express as a hexadecimal value with the left digit selecting which type of comparison of
eight (8) types to use. Range 0 to 7. The right digit of the hexadecimal value selects which text string to print.
Range 0 to 7. See the Compare String Section below. Range 00h to 77h hexadecimal value.

Compare String Control Codes

Compare Strings allow the printer output to print text messages according to numeric data that is received on the data
bus. For example: The state of a relay should be printed as “On” or “Off”. The value of the data on the data bus is
“00” or “01”, so a conversion with a compare string is necessary.

There are eight (8) types of comparisons, which will print combinations of the nine (9) Compare Strings as listed on the
screen below. Each type of Compare Strings have associated with it eight (8) text messages. As seen below “If
Binary Comparison is True” then text message #0 = “On” and text message #1 = “Closed”. The eight (8) text
messages for each type of Compare Strings may be accessed by clicking the click button to the left of each type of
Compare String.

Output an Ascii decimal representation of the unsigned Value added to Adder. The decimal

From the Data Bus Commands, we see that the address of the relay is at location 14 (0Eh). Since the relay
address ranges from 0 to 3, an Adder value of 1 converts the address to a range of 1 to 4, which is what the Magic
Module Relays are referred to as.
