Figure1-2 IP Modem principle chart
F2x16 consists of the following major components:
- A controlling unit made of a CPU (industrial 32-bit processor)
- WDT module
- Cellular module
- RS232/RS485 serial module
and the following physical Interfaces
- 1 x Power supply (+/-)
- 3 x LED indicators (ACT/Online/Power)
- 1 x RS232 port (RX, TX, GND) and 1xRS485 port(A,B)
-
2 x DI/DO + 1 x ADC (DI/DO can be customized to pulse c ounting)
The working principle is the following
After power on, the CPU controlling system functions will communicate with serial modules, it
will send AT commands to cellular wireless module and the wireless module will dial up to
connect to public internet. After device Dial up, online led will turn on, and F2x16 will provide
data transmission for serial devices connected to the switch module and the devices conected to
GPIO interface.
Any configuration is set using the user interface module which can also access to the power
module powering the unit. Power Interface has a standard 3.5mm terminal block interface and
built in phase reversal and over voltage protection, while SIM/UIM standard SIM card slots
support 1.8V/3V SIM/UIM cards and have built in 15KV ESD. This together with its casing
grants good immunity to power spikes, installation mistakes and e.m. discharge, for the safety of
users.
Modems can be set either using AT command or configuration software provided with the modem.
