| After updating the offered Arduino code and PC Application, it is possible to directly control the operation of up to 16 outputs from the PC |
| For Arduino boards: NANO -- UNO -- MEGA |
| Arduino pins are used: see connections (Active output state (Hi): ON = 5V OFF = 0V) |
| |
| Electrical note: (Recommendation: Use the following accessories for testing as well as for later use: Lnk1 - Lnk2 ) |
| Take care that the current load per each output Arduino pin does not exceed 10mA! |
| Some examples of hardware that can be connected to output pins (valid for PC USB power supply only): SSR1 - SSR8 |
| Other output elements can also be used, but take care of the power supply prescribed by the manufacturer user guide... |
| Note: Only the power supply of the device from the PC USB (total current consumption less than 300 mA)! |
| Recommended using an external voltage source 9V/1A (on dc plug or on VIN pin). |
| The last working state of all outputs is stored in the internal EPROM and when the power supply is interrupted (or RESET), the outputs are returned to the state before. |

| Download the HEX codes below, unpack and upload to the proper Arduino board (Use a free net tool for example XLoader) |
| 1. uc ATmega328-16MHz (MINI,NANO,UNO..): PCA116-m328 |
| 2. uc AtMega2560 (Mega(ATMEGA2560)......): PCA116-M2560 |
| |
| Description of HexCode commands ( You can test the uploaded code using some free serial communication software such as Termite (select: Append CR)): |
| AT command (ASCII characters + ENTER) - Baud 9600,8 Data bits, None Parity,1 Stop Bit - AT commands must be uppercase, lowercase invalid |
| AT - attention command (return OK) |
| I? - software code info (return ucAppName) |
| RKA - reading status of all outputs (return Kxx=X (xx=01-16 X=1/0) |
| RKxx - reading status of single outputxx (return Kxx=X (xx=01-16 X=1/0) |
| WKxxH - set single OUTxx at HI(5V) level (return Kxx=1 (xx=01-16)) - example: WK03H |
| WKxxL - set single OUTxx at LO(0V) level (return Kxx=0 (xx=01-16)) - example: WK16L |
| WKAH - set all outputs at high (5V) level (return Kxx=1 (xx=01-16)) |
| WKAL - set all outputs at low (0V) level (return Kxx=0 (xx=01-16)) |
