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
