Attaching The TC35 Terminal can be attached with two screws. Use screws approx. The TC35 Terminal can be attached to a top-hat rail using an additional fixture see the following page. Page 12 Installation Mounting kit for top-hat rail installation The TC35 Terminal can be attached to a 35mm top-hat rail using this mounting kit. There are two screws that are used tofix the top-hat rail adapter to the TC35 Terminal.

The module has a reasonable power consumption of approximately mA during calls and mA when idle with SIM card registered on the network. This article will summarize my experiment with this GSM module and describes some interesting findings.
Board layout Top view: Bottom view: The module has four 2. The onboard MAX is connected directly to the 5V power supply while the rest of the board works with 3. The onboard battery sockets also have some pins reserved for connection to external RTD sensors for battery temperature measurements. This makes sure all signals having the same ground reference. Upon applying power, the reset switch on the board must be pressed to power up the module.
The process is described in the Power-On section of the datasheet. If your microcontroller cannot communicate with the TC35 board despite apparently correct connections, try to reverse the TX and RX pins — some cheap TC35 boards might have incorrect labelling for some of the pins.
When the LED blinks at a pattern of 75ms on and 3 seconds off, this means the TC35 modem is ready to be used. In the above example, we are reading message 1 and message 2. For more information on AT commands, read this Wikipedia article.
