3 Chapter 3 EM-1240-DK Functionality This chapter includes information about the EM-1240-DK (carrier board of the EM-1240 Development Kit).
EM-1240 Hardware User’s Manual EM-1240-DK Functionality EM-1240-DK Function The EM-1240 Development Kit is a well-designed PCB board with complete layout. The kit helps users evaluate, develop, and integrate the EM-1240 Embedded Module into their systems and applications. Simply combine the EM-1240 Embedded Module with the Development Kit to start porting the relevant software, and create a solution for the applications you wish to implement.
EM-1240 Hardware User’s Manual EM-1240-DK Functionality Wiring Requirements This section describes how to connect the EM-1240 Development Kit to serial devices. You should heed the following common safety precautions before proceeding with the installation of any electronic device: y Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point.
EM-1240 Hardware User’s Manual EM-1240-DK Functionality ATTENTION This product should be mounted to a well-grounded mounting surface such as a metal panel. SG V- SG: The Shielded Ground (sometimes called Protected Ground) contact is the left most contact of the 3-pin power terminal block connector when viewed from the angle shown here. Connect the SG wire to an appropriate grounded metal surface.
EM-1240 Hardware User’s Manual EM-1240-DK Functionality Console Ports and Pin Assignments The serial console port on the EM-1240-DK is an RS-232 port with full modem signal. It is designed for serial console terminals, which can be used for local configuration. PPP is also supported to make it easy to set up a modem connection for long distance data transmission. You may use the Pin header of the serial console port to extend the serial port to other devices.
EM-1240 Hardware User’s Manual EM-1240-DK Functionality GPIO The EM-1240 Development Kit has 10 GPIOs. You may configure digital input channels and digital output channels by software. Note that the GPIO function will not work if you enable the SD signals function. Use the GPIO pin header for connecting with devices. See the following figure for GPIO pinouts.
