If USB doesn’t work for you, then surely Bluetooth is another option.

Prolific’s download page lists the unending “roll-off” of driver support for older chips – quite a few present-day chips are slated to get the axe come Windows 11 which is sure to surprise many people – perhaps this means the U1173B is going to stop working too for no good reason.
#Build arduino usb host shield drivers
Sick of rolling back drivers only to have them auto-update and unreliable quirks when attempting to lock the drivers, I resorted to using a newer U1173B lead which works fine. I noticed in 2017 that the adapter wouldn’t work under Windows 10 due to Prolific’s driver changes even though an older version of the driver did work. Getting a connection to a PC is pretty easy (in theory) using the USB to IR lead, however the grey U1173A version comes with a trap which I wasn’t aware of when I purchased the lead – it uses a old PL-2303X chip. While there’s very little to configure, often all you want is to grab readings from the DMM and that’s not all that difficult with the FETC? or READ? commands (both are equivalent). These are not officially documented, but Sigrok has a good summary of most of the commands.

It is no great secret that the Keysight handheld DMMs actually use a bastardised version of SCPI commands. Sometimes, I find myself needing an extra measurement device here or there, but not having the budget nor inclination to purchase a benchtop DMM just to get that capability, I set off to make the Keysight handheld DMMs I have a little more useful. Support on mobile seems to have dwindled slightly as well, with warnings about incompatibilities when running on more modern devices.Īs a test and measurement user, I have grown dramatically both in skill and in needs and running multiple-instrument tests is no longer a dream – it’s my everyday reality. due to low battery) and an attempt is made to stop the log. Unfortunately, the software has become quite dated and have some frustrating limitations and quirks, one of which includes loss of recording data on the PC if the Bluetooth connection fails (e.g.

These handheld DMMs have served me well, with one of the drawcards being the Keysight Handheld Meter Logger software which allows logging on PC via USB or both PC and mobile via Bluetooth. In the intervening years, I also ended up with a Keysight U1242B, a close cousin which has a few more features, so similar that some have unlocked the U1241B to U1242B by some EEPROM modifications. It was many moons ago when I treated myself to a proper name-brand DMM with some decent accuracy, an Agilent/Keysight U1241B complete with a U1173 USB to IR interface cable and a few other accessories.
