osys — in charge of general device functionality

(1)

owln — handles the Wi-Fi interface1

Function groups: String functions, trigonometric functions, date/time conversion functions,

encryption/hash calculation functions, and more

Variable Types: Byte, char, integer (word), short, dword, long, real, and string, as well as user-

defined arrays and structures

Notes:

1. These platform objects are either new or have new features (as compared to the EM2000).

2. TLS1.2 with RSA-2048 cryptosystem, supported on a single outgoing TCP connection.

Power Arrangement

The WS1102 can only be powered through the power jack.

The power jack accepts "small" power connectors with a 3.5mm diameter.

On the power jack, the ground is "on the outside," as shown in the figure below.

Serial Port

The WS1102 features a multimode RS232/422/485 port. Physically, the port is implemented as

a single DB9M connector.

Note: See Definition of RS422 and RS485 Modes for information on how these modes are

implemented on the WS1102.

Port pin assignment

In the RS232 mode, the serial port of the WS1102 has three output and three input lines. In the

RS422 mode, you get two output and two input line pairs. The RS485 mode offers one output

line pair and one input line pair. These are not independent — they operate in the half-duplex

mode.

The serial port of the WS1102 is controlled via the ser. object (see the TIDE, TiOS, Tibbo BASIC,

and Tibbo C Manual).
