1. Default PLL state after the external reset depends on the PM pin of the EM1000(W).

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

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

4. Default CTS/RTS mapping is different for each serial port:

5. Mapping of GA1000 and WA2000 control lines is fully flexible on the EM1000W. However, if the GA1000 or WA2000 module is installed on top of the EM1000, then the following mapping must be applied:

6. Older EM1000 and EM1000W devices did not contain the serial number. To find out if your EM1000(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. This property returns all 128 bytes of the serial number. The first 64 bytes are one-time programmable (OTP) with the sys.setserialnum method.


Supported Objects, Variable Types, and Functions


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