Connector DB-9F of RS-232 interface

Interface RS-232 of converters EDM106 has the standard 9-pin connector DB-9F. The pinout of the
connector is shown in Table 3.

LED Indication

The converters have three LED indicators:
RX – data reception,
TX – data transmission,
ST – indication of the connection of serial ports on TCP.
Algorithm of ST indicator operation:
Three timeslots of 1.2 s. for each interface (total - 3.6 s.):
Timeslot 1 – RS-232: one flash – 500 ms, pause – 700 ms.
Timeslot 2 – RS-485(1): two flashes – 250 ms each, pauses – 350 ms.
Timeslot 3 – RS-485(2): three flashes – 150 ms each, pauses – 250 ms.
Pause between the indication periods – 3.6 s.
