Section1 - Introduction System Features • • • • • • • With only 2 wires (no polarity) throughout the whole installation, the 2-wire DT system is a simplified installation system with minimum wiring and powerful features. The minimum wiring drastically reduces installation times and errors. By means of FM video modulation and ASK data transmission technology, system provides better protection against interference, which guarantees best color quality at all points of the installation.
Villa Application Although the DT system is mainly designed for the small apartment system usage, it can be used in villa or villa group applications. Multi Monitors can be installed in a family with the same User Code, or many houses can be connected as one system, and all of these Monitors can have calling conversation each other. 2 2 2 Apartment Applications This is the most common way that the system is used. One building or multi buildings can be connected as one system.

Step 1: Run the DT CONFIG software. Connect the USB-485 Convertor to the DMR11 Door Station and the PC, double click the software to make it running on the PC, then click the Namelist tap, the screen will be showed: Step 2: Edit the namelist. In the name input field, there is a Room No. column and a Name Label column, each User Code has a corresponding Room No. and a Name Label.
Camera Auto Switching When multi Door Stations or CCTV cameras are installed in the system, Monitor can display the video one after another. The Monitoring time for each Station or Camera must be set by the DT-CONFIG software manually to enable the Auto Switching function(DT-CONFIG-- >Parameter-- >Camera Switching Time). Also, you can touch the icon on the screen to monitor a specific camera only. Color Picture Memory Total 128 pcs picture can be stored in the Monitor.
User Code Setup In the DT system, every apartment must have a unique identification called User Code. The DIP switches are used to configure the User Code for each Monitor. • • • Bit-1 to Bit-5 are used to User Code setting. The value is from 1 to 32, which have 32 different codes for 32 apartments. When multi Monitors are installed in one apartment, these Monitors have to use the same User Code setting, and the Master/Slave mode should be set on the Monitor.

Section3 - Cables and Connections General Rules for Installation Connecting the Connectors Before screw the wire to the plug-in connector, it's important to process the wire in the correct way. See the following steps to connect the wire. 1. Strip the wire 2. Twist and bend it ~12mm 7~8mm 3. Put only the insulation-free part in the terminal Installation Height The recommended installation height of both Door Station and Monitor is from 160~165 cm.
Table of Cables and Distance The maximum distance of the wiring is limited in the DT system. Using different cables may also affect the maximum distance the system can reach. The farthest monitor DBC B C DPS When Monitor quantity < 20 Cable Usage A B C Twisted cable 2x0.75 mm2 60 60 30 Twisted cable 2x1 mm2 80 80 40 PS5 A When Monitor quantity > 20 Cable Usage A B C Twisted cable 2x1 mm2 70 30 20 Twisted cable 2x1.

Busy State Management Calls and busy state are managed according to the programmed system times • • • • • Pick-up waiting time: this is the duration from when a call is made from a Door Station to when the called Monitor is picked up; the system will cut off the call after this period of time.(the default setting is 30 seconds) Maximum talking time: this is the duration time that the indoor user can talk to the out door visitor.
Door Station Function 1. Call Forwarding: Every call button on the Door Station has a button ID,which is associated with a Monitor ID(Monitor address or code). When a call button is pressed on a Door Station: • • Door Station free: the Door Station will output the call forwarding tone (a long beep(Di~) in every 3 seconds) and the nameplate light will blink. The Door Station will output an end of conversation tone at the end of the communication.
System Setup What’s User Code In 2-wire DT system, each Monitor installed in system must be programmed with a calling address or calling number, which is User Code. For Monitor, User Code is defined by 1~5 bits DIP switchers on the connection board, according the User Code rules. For example, if you want to program the Monitor’s User Code to be “03”, the Monitor’s 1~5 bit DIP switchers should be set as: ON, ON, OFF, OFF, OFF(please refer to User Code table at section2-Monitor).
What's Slave Address 2-wire DT system is capable of connecting up to 4 Monitors in one apartment, which means they will have the same User Code, and will be called simultaneously. In this condition, the Monitors should be programmed as below: • • • • 1. All the Monitors of same apartment must be programmed with the same User Code on the DIP switches. 2. There is only one master Monitor in the one apartment, and the Slave Address of the master Monitor is set to 0. Each Slave Monitor should be set from 1~3.
Online search Online search function is designed for the purpose of getting a quick view of the Monitors installing situations, or to check if each of them works or not. This is very useful for installation maintain. There are 3 different ways to use the Online Search function, manually search, use the ID tab and use the DT CONFIG software. When the Online search is acting, the Door Station will search every Monitor with the User Code from 1 to 32.
2. Use ID tag The Door Station will be equipped with an Online search Card with a card number of 16666666, which is designed for the online search only. Show the Online search card on the card window one time within 3 seconds, the Door Station will start to search the Right column Monitors; show the Online search card on the card window twice within 3 seconds, the Door Station will start to search the Left column Monitors 16666666 3.
Section5 - DT CONFIG Software Introduction DT-CONFIG software is a powerful configuration and debug tool to setup the 2-wire system. As simplified software tools, DT-CONFIG allows installers to check and program Door Stations rapidly, which is especially useful in complex installation. DT-CONFIG allows you to view device properties, modify parameters, re-locate Call Button and establish Name List in a PC and then download to the Door Station.
Interface Preview 1. Main Menu (Information Menu) The Information tab shows the product Model, Hardware Version, Software Version, Serial No. , Access Control, Access Card Number information. On the Installer's Information tab, user can input the Project Name and Block Name for this Door Station. Note: Series No. is a unique number programmed in factory and used for tracking. Refer to the software document in the disk for detail information. 2.
3. Name list Setup This menu is for the name list input and download operations. All user namelist can be input and download to the Door Station and the Door Station will send the namelist to every Monitor in the system. 4. Access Control The Access Control tab included two sub tabs, Device Operation and File Operation. The Device Operation is used to add/delete user cards or master cards.
5. Debug Tool The debug tool is very useful when trouble shoot or maintain the system: • • • • • • User Code Range: To change the User Code start and end address, only set valid range will save more time. Online Check Button: Use this button to start Online searching, and the result will be showed in list window.(Online search function is designed for the purpose of getting a quick view of the Monitors installing situations, or to check if each of them works or not.
