Add serial support for OWON HDS200 series oscilloscopes and likely many other pieces of OWON test equipment. OWON HDS200 series devices host two USB endpoints, designed to facilitate bidirectional SCPI. SCPI is a predominately ASCII text protocol for test/measurement equipment. Having a serial/tty interface for these devices lowers the barrier to entry for anyone trying to write programs to communicate with them. The following shows the USB descriptor for the OWON HDS272S running firmware V5.7.1: Bus 001 Device 068: ID 5345:1234 Owon PDS6062T Oscilloscope Negotiated speed: Full Speed (12Mbps) Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 0 [unknown] bDeviceSubClass 0 [unknown] bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x5345 Owon idProduct 0x1234 PDS6062T Oscilloscope bcdDevice 1.00 iManufacturer 1 oscilloscope iProduct 2 oscilloscope iSerial 3 oscilloscope bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 0x0029 bNumInterfaces 1 bConfigurationValue 1 iConfiguration 0 bmAttributes 0x80 (Bus Powered) MaxPower 100mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 2 bInterfaceClass 5 Physical Interface Device bInterfaceSubClass 0 [unknown] bInterfaceProtocol 0 iInterface 0 ** UNRECOGNIZED: 09 21 11 01 00 01 22 5f 00 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0040 1x 64 bytes bInterval 32 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x01 EP 1 OUT bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0040 1x 64 bytes bInterval 32 Device Status: 0x0000 (Bus Powered) OWON appears to be using the same USB Vendor and Product ID for many of their oscilloscopes. Looking at the discussion about the USB vendor/product ID, in the link bellow, suggests that this VID/PID is shared with VDS, SDS, PDS, and now the HDS series oscilloscopes. Available documentation for these devices seems to indicate that all use a similar SCPI protocol, some with RS232 options. It is likely that this same simple serial setup would work correctly for them all.
