Protocol

The Hameg HMO series of scopes use SCPI as the communication protocol.

USB connection on OS X

To talk to the device over USB on OS X you need to ensure the HO720 interface card of the scope enumerates as a serial port. This does not happen automatically as the device ID of the HO720 card is not registered in the list of 'known devices' of the OS X FTDI driver.

To ensure you can communicate to the device, first install the - FTDI VCP driver for OS X.

Then, follow the instructions here and add the following section to the Info.plist:

<key>HamegScope</key>
<dict>
	<key>CFBundleIdentifier</key>
	<string>com.FTDI.driver.FTDIUSBSerialDriver</string>
	<key>IOClass</key>
	<string>FTDIUSBSerialDriver</string>
	<key>IOProviderClass</key>
	<string>IOUSBInterface</string>
	<key>bConfigurationValue</key>
	<integer>1</integer>
	<key>bInterfaceNumber</key>
	<integer>0</integer>
	<key>idProduct</key>
	<integer>60786</integer>
	<key>idVendor</key>
	<integer>1027</integer>
</dict>

Connect the cable, power on the scope, ensure the USB interface is enabled under Setup > Interface on the device. A new serial device will be generated and you should be able to get the device info with:

$ sigrok-cli --driver hameg-hmo:conn=/dev/cu.usbserial-xxxxyyyy --scan
