4. Optional External Reader Wiring:

The MRDT supports the connection of a standard reader. This external reader is connected to J3 pins 9

through 14, see table 1. The power for this reader can be passed through from the 12Vdc input power of

the MRDT. D1/D0 and CLOCK/DATA signaling is supported as well as the LED and buzzer. This reader

port configuration is set via the host software. Door monitoring inputs and the door strike relay are

defined on another device (SIO), if required. The total cable length is limited to 500 feet (152 meters).

5. Hardware Configuration:

Jumpers:

J1, J5, J6 Factory use only. Always open.

Table 2-1

S1-1: Proper termination practices must be followed to insure proper operation. If the MRDT is the

last device on the RS-485 bus, termination should be set to ON.

S1-2: Used for testing. This switch forces RS-485, MSP1, 38,400 baud and address 31. The current

saved configuration is displayed when in the configuration mode.

S1-3: When set to ON, this disables the ability to use the keypad for changing the configuration.

This decreases the possibility of unauthorized persons from altering the configuration.

S1-4: Factory use only, set to OFF.

6. Software Configuration:

Firmware revision 1.62.0 and higher supports the following communication protocols:

* MSP1

* OSDP *

* Reader Port (TTL)

The MRDT displays the PowerUp screen when power is applied:

Press Two Key

For Set Up 

Press these two keys (F1 & F4) to enter the configuration mode, otherwise the unit will initialize normally.

Configuration mode:

0000047582-1.62B

EXIT Configure 

The first line displays the unit's serial number, firmware revision and assembly revision.

The second line prompts to EXIT configuration mode (press F1) or enter the CONFIGURE mode (press

F4).

Prompting sequence:

After you make your entry, wait (3 seconds) to be prompted to accept or change an entered value.

If a prompt is not responded to after 2 minutes, the MRDT will return to the PowerUp Complete screen.

Comm:

1=RS-485 Select RS-485 if the MRDT will be using MSP1 or OSDP * protocol

2=Rdr Port Select Rdr (Reader) if the MRDT will be connected to a Series 1 MR52 reader port

Protocol: (bypassed if Rdr Port was selected)

1=MSP1 Select MSP1 if connected to: - RS-485 downstream communications port. See note 1

- Series 2 MR50 or MR52 reader port. See note 2

- EP1501, EP1502 or MR51e reader port. See note 1

2=OSDP * Select OSDP if using OSDP communications protocol

Baud Rate: (bypassed if Rdr Port was selected)

1=9600 Select for 9600 baud (default for standard reader port using MSP1 or OSDP * protocol)

2=19.2 Select for 19,200 baud

3=38.4 Select for 38,400 baud

4=115.2 Select for 115,200 baud *

Comm Address: (bypassed if Rdr Port was selected)

Enter communication address: 00 through 31 (must enter two digits).

Use address 00 if connected to a standard reader port.

Use address 01 for the second OSDP * reader on EP1501's reader port 1.

Back Light:

Enter the number of seconds the back lights will be illuminated after the last key was pressed:

00-99 seconds (must enter two digits).

00 = always off

99 = always on

LED:

Selects the LED drive type to match the optional external reader connected to the reader port.

1-Wire: Standard 1-wire interface (High = Red, Low = Green)

2-Wire: Brown wire controls Red LED (High = Off, Low = On)

Orange wire controls Green LED (High = Off, Low = On)

(No Buzzer)

2W/Special:Use this mode when interfacing to Dorado (HID) reader model 780.

Save Configure:

Select Yes to save the configuration. The PowerUp Complete screen will appear and the MRDT will

initialize.

Select No to discard any changes to the configuration and go back to the PowerUp screen.

Note 1: The EP1501 and MR51e reader port 1 may be configured as a standard reader port or a RS-485

communications port. The standard reader port supports both MSP1 and OSDP * protocols. The

RS-485 downstream communications port only supports MSP1 protocol.

Note 2: Series 2 MR50: firmware revision 1.24.0 and higher. Series 2 MR52: firmware revision 1.23.0

and higher.

7. Status, Off-line, LED/Buzzer, and Downloading Displays:

Status Display *:

Pressing the arrow and command keys simultaneously while MRDT is running in the normal mode will

display the summarized information for ten seconds.

Status Display example:

0000074582 1621B

485MSP1 38400 05

The top line contains the 10 digit serial number, firmware revision, and the hardware assembly version.

The bottom line contains the communication type, baud rate, communication address.

Communication type: Rdr Port, 485MSP1, or 485OSDP

Baud rate: 9600, 19200, 38400, or 115.2

Address = 00-31

Off-line Display *:

When the MRDT is not communicating to the SCP/EP controller communication port or the reader port,

the following will be displayed:

“ooo “

“ ooo”

If the SIO of the reader port that the MRDT is connected to is off-line with the SCP/EP controller, the

following will be displayed:

“…“

“…”

Bi-color LED/Buzzer:

The LED and buzzer are controlled by the LED and buzzer input except as noted below.

Firmware Downloading Display *:

If the MRDT is power up with corrupted or missing application code the following message is displayed:

FirmwareRequired The application code must be downloaded to the MRDT.

When the MRDT is receiving downloaded firmware the following will be displayed:

“Downloading x”(x = period, lower case o, and zero animatedly displayed in sequence).

When in either of the above modes, the LED flashes: 0.1 second Green, 0.1 second Off.

After firmware download has completed the PowerUp screen will appear and the MRDT will initialize.
