© Tibbo Technology Inc.
The above pin assignment is standard for all Tibbo devices with the universal port
(for example, see the serial port of the DS1102).
LEDs
There are eight LEDs: five red and three green. Red LEDs are connected to TX, RTS,
DTR, FD/-HD, and -232/422-485 lines. Green LEDs are for RX, CTS, and DSR.
All LEDs are buffered (with logic gates) and light up for the LOW state of
corresponding control lines.
