Title: AJ102 Data Concentrator Unit User Manual Ver. 1.4 Page: 9 of 23 4 Function Characteristics 4.1 Clock Management DCU has a RTC which complies with IEC 62052-21/62054-21. At reference voltage and reference temperature (23°C), clock accuracy is better than ±0.5 s/day. The RTC supports leap year, day light saving time. In case of power off, clock of DCU is active for at least two years after manufactured with battery support. DCU automatically synchronizes its clock with SNTP server every day.

Title: AJ102 Data Concentrator Unit User Manual Ver. 1.4 Page: 13 of 23 5 Communication Interfaces The DCU provides following communication interfaces: Function Local WAN LAN Interface Baud Rate Protocol Optical port 9,600 bps DLMS/COSEM HDLC profile RS-232 115,200 bps 3G Downlink transfer: max. 85.6 kbps Uplink transfer: 42.9 kbps DLMS/COSEM TCP/IP Profile. RJ-45 Ethernet 10/100M DLMS/COSEM TCP/IP Profile.
Title: AJ102 Data Concentrator Unit User Manual Ver. 1.4 Page: The 3G communication parameters are generally programmed in the factory. It is also possible to change the communication parameter remotely or locally. Refer to LED indicators chapter for the communication status indication. 5.2.2 Ethernet Communication DCU supports one Ethernet port which can also be used for remote communication. 5.
Title: AJ102 Data Concentrator Unit User Manual Ver. 1.4 Page: 6 Security 6.1 Physical Security The DCU has two seals for the terminal cover, one seal for the RF antenna box. It is impossible to access the DCU internal part unless physically and transparently destroy the seals and the DCU face or terminal cover. The DCU records the main cover removal event and terminal cover removal event in both power on condition and power off condition. The DCU detects the meter dismantle/removal event. 6.
Title: AJ102 Data Concentrator Unit User Manual Ver. 1.4 Page: 16 of 23 7 Transportation and Storage The DCU should be placed on pallet and the height should not exceed 5 layers. The storage condition should be clean, with an environmental temperature of between -25°C and +85°C, relative humidity of less than 95% and with an absence of rusty matter in the air. 8 DCU Installation 8.1 Installation Environment DCU should be installed at a dry and well-ventilated place.
Title: AJ102 Data Concentrator Unit User Manual Ver. 1.4 Page: 8.4 Installation Guide 8.4.1 What You Need To install DCU, you should prepare: Screw driver: FD3 screw driver for main terminal screw. Fixing screw and Hook screw: M5 slotted countersunk (flat) head tapping screw. Electric drill with M3 broach for metal meter box installation. Electric drill with M5 broach and plastic plug for concrete wall installation. 8.4.
Title: AJ102 Data Concentrator Unit User Manual A: Hook, Ver. 1.4 Page: 18 of 23 B: Fixing hole Step 3: Install RF antenna 1) Remove the RF antenna cover 2) Connect tightly the RF antenna to the RF antenna connector 3) Remove the cut-out of the RF antenna cover 4) Install the RF antenna cover, the RF antenna cable should pass through the cut-out 5) Fix the screw 6) Seal the RF antenna cover. Note: Before install the RF antenna, you may need to fix the RF antenna on the cabinet of the DCU.
Title: AJ102 Data Concentrator Unit User Manual Ver. 1.4 Page: 19 of 23 Step 5: Install 3G external antenna Tightly connect the external 3G antenna to SMA connector on the 3G module. Note: 1) It’s better to install 3G antenna without removing the 3G module from the DCU. 2) Before install the 3G antenna, you may need to fix the 3G antenna on the cabinet of the DCU. Make sure the 3G antenna is fixed at the bottom of the 3G module, and as show in figure shows are as follows.
