DS1202 Basic Programmable Controller

The DS1202 is a miniature BASIC-programmable controller designedprimarily for serial-over-IP and serial control applications. It comespreloaded with a fully functional serial-over-IP application.

The unique feature of the DS1202 is its multi-channel serial port.The device has a single DB9M connector and is priced as a single-portdevice, yet packs four independent serial channels. Have no use forthose DSR and DTR lines? Turn them into RX and TX of an additionalserial channel. Don't want CTS and RTS either? That's one more channel!In total, there are 15 different configurations to choose from.

• Sock — socket comms (up to 16 UDP, TCP, and HTTP sessions).
• Net — controls Ethernet port.
• Ser — in charge of serial channels.
• Io — handles I/O lines, ports, and interrupts.
• Fd — manages flash memory file system and direct sector access.
• Stor — provides access to the EEPROM.
• Romfile — facilitates access to resource files (fixed data).
• Pat — "plays" patterns on green and red status LEDs.
• Button — monitors the setup button.
• Sys — in charge of general device functionality.

Function Groups: Strings functions (21 in total!),date/time conversion functions, and hash calculation functions (md5 andsha1).
