EM-1220 Embedded Module Functions
The EM-1220 Embedded Module is designed to be integrated directly into the user’s system and application.
The module has two software-selectable RS-232/422/485 serial ports, dual 10/100 Mbps LAN ports, 1 RS-232
console port, and GPIO/SD signals. In addition, the EM-1220 uses the Moxa ART ARM9 32-bit 192 MHz
communication processor, which ensures excellent performance for data transmission.
The pre-installed μClinux Kernel 2.6.9 makes it easy for users to develop programs for a variety of applications.
The EM-1220 is an ideal solution for manufacturing automation, intelligent transportation monitoring, and
remote device control.
RS-232/422/485 Serial Ports
The EM-1220 Embedded Module has 2 software-selectable RS-232/422/485 serial ports. Pin assignment
diagrams are shown in a later section. The ports can be configured by software. Please refer to Software User’s
Manual for details.
Console Port
The EM-1220 Embedded Module has 1 console port for onsite configuration. The port supports TxD, RxD, GND,
and TTL signals.
LAN Ports
The EM-1220 Embedded Module has 2 10/100 Mbps LAN ports that can be used to set up a redundant Ethernet
network for non-stop operation, and the on-board transformer provides 1.5 KV isolation protection.
SD Signals
The EM-1220 Embedded Module provides SD signals for storage expansion. Designers can use these signals to
create an SD socket. Note that you can use a Secure Digital (SD) memory card compliant with the SD 1.0
standard to provide up to 1 GB of additional memory space. However, the SD signals share the same
mechanical layout with the GPIO. When you enable the SD signals, the GPIO function will be disabled, and vice
versa.
GPIO
The EM-1220 Embedded Module provides 10 software-selectable GPIOs. Note that users can choose to enable
either the SD Signals or the GPIO function, but not both. When you enable the GPIO function, the SD Signals
will be disabled.
Pin Assignments
There are two 34-pin pin headers on the EM-1220 embedded module. To use the EM-1220 Embedded Module
to develop your own independent system, refer to the following tables for the pin assignments of jumpers J1
and J2.
