This revision is from 2019/01/24 21:50. You can Restore it.

Manual IP switch MK2 is delivered with two parts - IP relay diver KIT (needs to assemble) and assembled IP control. Both parts have firmware installed and automaticaly pair in local network with available DHCP server.

Quick start guide in two step

IP Switch relay driver KIT

Assembly KIT by this instructions.
Connect ethernet to local LAN with available DHCP server
Connect 5V power DC adapter
Set NET-ID-sufix with BCD switch in the range 0-7, for example 0.

IP control

This part is assembled and tested.
Connect ethernet to local LAN with available DHCP server
Set NET-ID-sufix with bottom side BCD switch in the range 0-7, the number must be the same as on IP-switch relay driver.
Connect micro USB cable for power supply.
Wait to pair and start to use.

CONFIGURE INPUTS

Individual functionality is enable or disable with coment/uncoment preset line

First sets global frequency rules which they choose BAND number by frequency with a resolution of one Hz. Also may be use for partition one band to more subbands.

//Freq Hz from       to   Band number
     {1810000,   2000000},  // #1 [160m]
     {3500000,   3800000},  // #2  [80m]
     {7000000,   7200000},  // #3  [40m]
    {10100000,  10150000},  // #4  [30m]
    {14000000,  14350000},  // #5  [20m]
    {18068000,  18168000},  // #6  [17m]
    {21000000,  21450000},  // #7  [15m]

Input Serial

Activate uncomment line

#define INPUT_SERIAL

Not need any hardware settings, only send via USB to serial line ascii characters in preconfigured baudrate.

X,YYYYYYY\n

X - band output in range 0-14, if activate BCD output range is 0-10 because 11-14 reserved for BCD. 0 (zero) = no output will be turned on.
YYYYYYY - frequency in Hz - has no effect on the output relays, used if any CIV/CAT outputs activated.
\n - is LF Line Feed (0A in hex)

CONFIGURE OUTPUTS

You can uncomment more than one output, but not all combinations are worked.

Always usable - may all at once.

8 output driver - allways enabled
Yaesu BCD - allways enabled except activate Yaesu BCD input
Serial echo

Only one from (not available during active Frequency request option (available only one TXD line)

//=====[ Outputs ]============================================================================================
// #define SERIAL_echo        // Feedback on serial line in same baudrate, CVS format <[band],[freq]>\n
// #define ICOM_CIV_OUT       // send frequency to CIV ** you must set TRX CIV_ADRESS, and disable ICOM_CIV **
// #define KENWOOD_PC_OUT     // send frequency to RS232 CAT ** for operation must disable REQUEST **
// #define YAESU_CAT_OUT      // send frequency to RS232 CAT ** for operation must disable REQUEST **

8 output driver

Allways enabled.

How to expand outputs

Band decoder use internal shift register with 8 outputs. This is free expandable. You can connect next shift register to P5 output connector. Schematics module for serial chain linkink on picture.

And sets number of all shift register in firmware

internal = 1
internal + one external =2

int NumberOfBoards = 2;    // number of eight byte shift register 0-x

SERIAL ECHO

Activate uncomment line

#define SERIAL_echo

Requires setting

#define SERBAUD  9600

You can set rules to select BCD output, dependency to detected band input.
