MOUNTING INSTRUCTIONS IN STEPS
Before you start mounting the DIG-M, read carefully “Safety and Precautions” and
follow these steps:
1. Slide the unit along the guides of a standard 35 mm DIN rail and fix it to the rail
by means of the black locking clip on the enclosure. Mind the correct position and
mounting dimensions shown in Fig. 1 Mounting dimensions and Fig. 2 Mounting
position.

2. Connec t the Sentera slave devices via Modbus RTU on the lef t RJ45 socket.
3. If applicable, the BMS or external Modbus RTU master can be connected via the
right RJ45 socket.
4. e DIG-M unit needs PoM (24 VDC). So either, the Slave or Master channel must
be powered with 24 VDC.
Do not connect both circuits with PoM 24 VDC power supply simultaneously!

Bootloader
anks to the bootloader functionality, the device firmware is updated via Modbus RTU
communication. To enter ‘Boot mode”, put a jumper onto pins 3 and 4 of the P1 header
and restar t the power supply (see Fig. 4). Once ‘Boot mode’ is activated, the firmware
can be updated via SM Boot application (part of 3SModbus software suite).

VERIFICATION OF THE INSTALLATION INSTRUCTIONS
■
Green LED1 indicates that the unit is supplied and that the Modbus RTU
communication with slave devices is ac tive.
■
Green LED2 indicates active communication with the Internet. i.e. DIG-M
successfully communicates with the Sentera Web-Server sending parameters
to the Cloud.
■
Slowly blinking red LED3 indicates system error (connection to the Cloud has
been lost).
■
Fast blinking LED3 indicates that bootloader mode has been entered (see Fig. 6).
■
Blinking LEDs on the RJ45 sockets indicate that packages are transmitted via
Modbus RTU.
■
If this is not the case, check the connections.

ATTENTION
e status of the LEDs can be checked only when the unit is energised. Take the
relevant safety measures!
TRANSPORT AND STORAGE
Avoid shocks and extreme conditions; stock in original packing.
WARRANTY AND RESTRICTIONS
