The DS1002SK is a starter kit containing the DS1002 (including its usual accessories, i.e. terminal block adapters, mounting kit and secondary cover), a U.S. power supply, a DB9F-to-DB9F null modem serial cable (for connection to PC), and a straight-through Ethernet cable.

The DS1002 is a 4-port programmable industrial controller designed primarily for serial-over-IP and serial control projects. It comes pre-loaded with a fully functional open-source serial-over-IP application.

The four ports of the DS1002 can be programmed for RS232, RS422 or RS485. Four terminal block adapters are included for you to use instead of the DB9 connectors built in.

A version of this controller with isolated ports is available — the DS1003SK.

The DS1002 is programmable in Tibbo BASIC and/or Tibbo C which also provides a complete IDE for debugging. The functionality of the DS1002 is determined by whatever Tibbo BASIC/C application it is running. It is perfectly suited for work as an intelligent serial controller, a serial device server, or a serial communications gateway.

It requires 10-18V DC power, which can be provided through a 3.5mm coaxial jack (center positive) or a two-pole screw terminal. The kit's included power supply will plug into the coaxial jack.

Other versions of this controller are available that add wireless connectivity in the form of GPRS, WiFi or both.

4-port Serial Controller Programming

Platform Objects

• sock — socket comms (up to 16 UDP, TCP, and HTTP sessions)
• net — controls Ethernet port
• ser — in charge of serial channels
• ssi — up to 4 serial synchronous interface channels (for SPI, I2C, etc.)
• io — handles I/O lines, ports, and interrupts
• 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 — accesses the internet over an ADSL modem
• ppp — accesses the internet over a serial modem (e.g. GPRS)
• pat — "plays" patterns on five status LED pairs
• beep — generates buzzer patterns
• button — monitors the setup button
• sys — in charge of general device functionality

Function Groups

• Strings functions (21 in total)
• Date/time conversion functions (8)
• Encryption/hash calculation functions (AES128, RC4, MD5, SHA-1)

Variable Types

• Byte, char, integer (word), short, dword, long, real, string, plus user-defined arrays and structures.
