1. Introduction
This manual is the reference when setting up the InduBox SM M4 modem for your
application. Because of the nature of this product and its field of application, some
degree of technical background knowledge regarding the application and data-
communication is assumed.
The InduBox SM M4 modem is a versatile communication device designed to provide
a flexible data communication solution for an industrial environment. The InduBox SM
M4 modem contains a number of options to accommodate different communication
speeds, power supplies and interfaces.
This modem has an extended TCP/IP stack implementation, and is able to connect non-
IP devices to an IP network over an Ethernet or SM link.
The main specifications of the InduBox SM M4 are :
InduBox wall mountable housing
Configuration, setup and monitoring via UI / HTML pages
8 x status LEDs
10/100 Mb Ethernet interface
full RS-232 DCE serial interface
galvanic isolated 2-wire RS-485 serial interface
galvanic isolated 3-wire RS-232 serial interface
1 x passive galvanic isolated digital input
Sierra Wireless HLx SM module
SIM card holder internally
FME antenna connector
powerful Cortex M4 processor
2Mb EEPROM [262.144*8 bit]
64KB FRAM [8.192*8 bit]
Thanks to the powerful Cortex M4 processor it's possible to add IP basic routing and/or
standard RTU protocols like IEC60870-104 or other customer specific protocol
demands.

2. Block Diagram
The block diagram below details the location and interconnection of the different
functional units within the modem. The most important units are briefly described.
AC/DC power supply
The mains supply (ac) must be connected to the InduBox SM M4 modem via a 2 pin
terminal block with screw contacts. Make sure the voltage supplied to the modem is in
the range of the InduBox SM M4 input voltage (see specifications for details on
voltage range).
Configuration Interface
The InduBox SM M4 modem has one complete (TxD, RxD, DCD, DTR, RTS, CTS, RI
and ND) RS-232 interface. This RS-232 interface is not isolated and can be used to
configure and/or debug tracing. This interface has a RJ-45 connector.
Ethernet Interface
The InduBox SM M4 modem has one standard 10/100 Mbit/s ethernet LAN interface.
This interface can be used to configure the modem via the HTML UI.

Isolated DTE interfaces
The InduBox SM M4 has 2 galvanically isolated serial interfaces :
3- wire RS-232 (RxD, TxD, G D’)
3- wire RS-485 (A, B, G D’)
Those interfaces are galvanically separated and can be used to connect a serial device.
Both interface connections are done through one RJ-45 connector.
The V' - pin can be used for external reset (V') or for powering (100 mA Imax) an
external device (+5V'), selectable via a JP6.
8x Status LED’s
The InduBox SM M4 has 8 status LED’s.
SM module
The InduBox SM M4 is using a Sierra Wireless CF3 footprint SM module as WAN
device. Thanks to the Sierra Wireless CF3 HL footprint for the WAN module, the InduBox
SM M4 offers the flexibility to easily migrate communication technologies, thus making
it future proof. Depending on the application, the modem can be provided with standard
3 PP cellular 2 PRS, 3 UMTS, 4 LTE, LPWA (low power wide area), LTE Cat-M1
or NB-IoT. LPWA with 3 PP 2 PRS fallback is also possible. Most modules are
available for global or NAM, EMEA and APAC only regions.
The following options are possible (Q3 2018) :
3 PP
HL6528 – quad band SM/ PRS & SM Data
HL6528RD – quad band SM/ PRS
HL8518 – dual band HSPA, SM/ PRS/ED E
HL8548 – quad band HSPA, SM/ PRS/ED E
HL7690 – FDE band LTE Cat-1 (*)
HL7692 – FDE band LTE Cat-1 with dual band SM/ PRS/ED E fallback (*)
LPWA
HL7800 – LTE Cat-M1, NB-IoT
HL7802 – LTE Cat-M1, NB-IoT with dual band SM/ PRS fallback
(*) only with 1-SISO antenna connection

1. Disconnect the mains power and DTE interface.
2. Open the InduBox SM M4 enclosure.
3. The SIM cardholder is placed in the upper right corner onto the PCB.
4. Slide the upper part to the LEFT position.
5. Rotate the SIM card holder upper part to the upright position.
6. Insert the SIM card into the upper part of the card holder.
7. Rotate back and close the upper part of the SIM cardholder
8. Finally slide the upper part to the right (LOCK) position.

5. Ports and Connectors
Before you start the installation, take a moment to become more familiar with the
possible connections to and from the InduBox SM M4 modem.
The InduBox SM M4 has three types of connectors; a mains terminal block screw
connector, two RJ-45 connectors and one FME connector.
Disconnect the mains power before connecting or
disconnecting the power and/or DTE plugs !
5.1 Mains Power Connection
PI
1 N
2 L1
Always disconnect the mains power before connecting or disconnecting the power plug.
Make sure the voltage supplied to the modem is within range of the InduBox SM M4
input voltage (see specifications for details on voltage range).
There is no fuse or circuit breaker built-in to the InduBox SM M4, this must be added
externally.
When the InduBox GSM M4 modem is connected via a standard mains plug, the
used mains socket must be directly accessible and easy reachable.

5.2 Isolated Serial DTE Interfaces
The isolated serial interfaces are galvanically separated from the main circuits of the
InduBox SM M4 ; the RxD and TxD lines are separated via an OptoCoupler, a second
5 Vdc power supply is created via an additional DC/DC convertor.
Two isolated serial interfaces are possible on the same RJ-45 connector :
RS-232 3-wire & '+V'
RS-485 3-wire & '+V'
