Installing foot pedals on Computer is Very Easy See Below Step by Step Method of Installation.

3 Types of Female Plugs used in Transcription Foot Pedals

Install 9 Pin / Serial / Com Port

Locate the com-port socket at the back of your computer as Seen in Picture Also called DB9 or 9 Pin.

1. Plug the pedals in and restart the computer.

2. Open Express Scribe. Open Settings and on the Control tab enable 'Use Foot Pedal Playback control'.

3. Select the correct COM port - e.g. COM1 (Serial).

4. Click the Foot Pedal Control Setup Wizard button.

5. Follow the instructions on the screen. If a Foot Pedal Hardware Error message saying 'Unable to open COM port' is displayed, the COM port you selected in Step 5 is not the COM port that the foot pedal is connected to. Select a different COM port and run the Foot Pedal Control Setup Wizard again.The pedals should now be correctly installed.

Install15 Pin / Joystick / Game Port

Locate the game-port socket at the back of your computer as Seen in Picture Also called DB15 or 15 Pin. It is probably in the sound card .

1. Plug the pedals in and restart the computer.

2. Once the computer has restarted go to Start - Control Panel in Windows.

3. Open 'Game Controllers'.

4. Select Add -> 2 axis, 4-button.

5. Select 'test' and 'test your pedals'. Pressing a different pedal should cause a different number to light up.

6. Close the control panel and open Express Scribe.

7. Open Settings and on the Control tab and tick 'Use foot Pedal Playback control'.

8. Select 'game port 1' (if you only have one game port)

9. Click on the 'Foot Pedal Control Setup Wizard'.

  • 3ESP Easy

The number of GPIO pins on the ESP module can be expanded with a IO Expander. We will use the PCF8574 that provides 8 more pins that can be used as input or output. This way it becomes possible to control an 8 channel relay board.

Each individual pin can be used as either input or output. It can also be helpful in improving system stability when using ESPEasy for actuators. It is an unfortunate reality that the ESP reboots randomly. This can be extremely annoying depending on your application. The PCF8574 keeps the GPIO states as the ESP reboots (as long as power is not disconnected).

The PCF8574 needs to be connected through the I2C interface. This chip is compatible with 3V3 and therfore can be connected to the ESP without levelshifters.

Connections

See below example for ESP01. It can be connected to any two GPIOs capable of runnning I2C (GPIO 1&3 on a Sonoff for example)

When using the PCF8574 be aware of the extremely limited current the GPIO pins can source. If LED or Relays are to be driven (even just the transistors) , make sure to use the GPIO to sink the current --> connect device to 3.3V VCC and GPIO. Switch device on by setting the GPIO to Low. If necessary 2 GPIO can be tied together (must also always be switched together) to sink more current.

Configuration depends on how you want to use a certain port on this device. Ports are numbered 1 to 8 (if you have a single PCF8574 connected)

Input

To have an input port act as an input switch device (just like with the default onboard GPIO pins) you need to edit a ESP Easy task and select the 'PCF8574 input' device.

You then select the portnumber and additional configuration depending on the controller type. For Domoticz, you enter the IDX that was allocated by Domoticz for this virtual switch.

Portnumbering depends on the I2C address used:

For the PCF8574:

A0:A1:A2:Address:Port range:
0000x201 - 8
1000x219 - 16
0100x2217 - 24
1100x2325 - 32
0010x2433 - 40
1010x2541 - 48
0110x2649 - 56
1110x2757 - 64

For the PCF8574A:

A0:A1:A2:Address:Port range:
0000x3865 - 72
1000x3973 - 80
0100x3A81 - 88
1100x3B89 - 96
0010x3C97 - 104
1010x3D105 - 112
0110x3E113 - 120
1110x3F121 - 128
