EM1206 and EM1206W Platforms

Top  Previous  Next

The difference between the EM1206 and EM1206W platforms is that the EM1206W additionally includes the Wi-Fi  (wln.) object (requires an external GA1000 add-on module). All other features of these two platforms are exactly the same.

Ethernet /WinPCap transport


1.The sock.allowedinterfaces property refers to the Ethernet interface as "NET", Wi-Fi — as "WLN", PPP — as "PPP", and PPPoE — as "PPPOE". Sock.targetinterface and sock.currentinterface properties rely on the pl_sock_interfaces enum, whose members differ depending on the platform.

2.Surrounding hardware may dictate which GPIO lines must be used as inputs and which — as outputs.

3.Default CTS/RTS mapping is different for each serial port. Notice that CTS and RTS lines in default mapping interfere with each other. Do remember to select meaningful mapping for these lines!




Port 1


0- PL_INT_NUM_0 (0- PL_IO_NUM_0_RX0_INT0)

Port 2


1- PL_INT_NUM_1 (1- PL_IO_NUM_1_TX0_INT1)

Port 3


2- PL_INT_NUM_2 (2- PL_IO_NUM_2_RX1_INT2)

Port 4


3- PL_INT_NUM_3 (3- PL_IO_NUM_3_TX1_INT3)


4.Mapping of GA1000 control lines is fully flexible on the EM1206W. However, if the EM1206EV board is used, then the following mapping must be applied:


15- PL_IO_NUM_15


14- PL_IO_NUM_14


12- PL_IO_NUM_12


13- PL_IO_NUM_13


11- PL_IO_NUM_11


5.Older EM1206 and EM1206W devices did not contain the serial number. To find out if your EM1206(W) has the serial number onboard, try to read this serial number with the sys.serialnum R/O property. If this property returns an empty string, then the serial number is not present. Sys.serialnum returns all 128 bytes of the serial number. First 64 bytes are one-time-programmable (OTP) with the sys.setserialnum method.

Supported Objects, variable types, and functions

Sock — socket communications (up to 16 UDP, TCP, and HTTP sessions);

Net — controls the Ethernet port;

Wln — handles the Wi-Fi interface (only available on the EM1206W platform, requires GA1000 add-on module);

Ser — in charge of serial ports (UART, Wiegand, and clock/data modes);

Ssi  — implements up to four serial synchronous interface (SSI) channels, supports SPI, I2C, clock/data, etc.;

Io — handles I/O lines, ports, and interrupts;

Kp — scans keypads of matrix and "binary" types;

Rtc — keeps track of date and time;

Fd — manages flash memory file system and direct sector access;

Stor — provides access to the EEPROM;

Romfile — facilitates access to resource files (fixed data);

Pppoe — provides access to the Internet over an ADSL modem;

Ppp — provides access to the Internet over a serial modem (GPRS, POTS, etc.);

Pat — "plays" patterns on up to five LED pairs;

Beep — generates buzzer patterns;

Button — monitors the MD line (setup button);

Sys — in charge of general device functionality.


These platforms support the standard set of variable types and functions (a.k.a. "syscalls").
