Digitek DT4000ZC cable
The Digitek DT4000ZC (and the rebadged TekPower TP4000ZC) ship with this RS232 to 3.5mm stereo plug cable. The ring on the plug is left unconnected.
The cable works on the assumption that TX (pin 3) and DTR (pin 4) are at a fixed voltage and will not be toggled. TX should be below -3 V, and the resistor acts as a pull-down. DTR should be abouve 3V. The photodiode/phototransistor in the DMM will pull the RX pin above 3V when the IR diode is on.
Hardware:
- SMD resistor between TX and RX pins.
Works with:
Where to buy:
- The cable ships with the multimeter. It's unclear whether it can be bought standalone (without DMM).

UNI-T UT-D04
The UNI-T UT-D04 (see also uni-trend.com.cn) is a USB/HID cable for various UNI-T multimeters (and rebranded models) with PC connectivity.
There have been (at least) two versions of this cable, the older one with Hoitek HE2325U USB/HID chip, the newer one using a WCH CH9325 USB/HID chip.
See Device cables/Info#UNI-T_UT-D04 for more details (such as lsusb -v output) about the cable.

Voltcraft sells rebranded, UNI-T made DMMs, and also ships with the same USB/HID cable, but with a Voltcraft logo/marking on it. It is likely that Voltcraft also shipped both the old and new version of the cable at some point.

V&A VA4000
The V&A VA4000 is a USB PC interface cable for various V&A multimeters.
It seems there have been at least two different revisions of the cable. The older one used a Sunplus SPCP825 USB-to-serial chip (see here, here, or also check the drivers from here), the newer revisions use a Prolific PL2303HX chip.
See Device cables/Info#V.26A_VA4000 for more details (such as lsusb -v output) about the cable.
Hardware (old cable version):
- USB to serial chip: Sunplus SPCP825
- Crystal: ?
Hardware (new cable version):
- USB to serial chip: Prolific PL2303HX YR0903A
- Crystal: 12MHz

Sound level meters
Colead SL-5868P cables
Some distributors sell the Colead SL-5868P sound level meter with a set of two cables: one 3.5mm jack to female DB9, and one male DB9 to USB, which has a Prolific PL-2303 chip in the DB9. This cable does not work; the device's serial port needs a 2.5mm jack.
A really bad idea

- USB to serial chip: Prolific PL2303HX LFC10073A
- Crystal: 12MHz
Works with:
- Tondaj SL-814 (maybe other Tondaj gear?)
Where to buy:

Programmable electronic loads
M133
The M133 (vendor unknown) cable ships with the ATTEN ATZ9711 programmable electronic load. It's unclear whether this is a custom cable for this device, or a generic RS232 isolator cable.
The 28-pin chip is a standard Prolific PL-2303HX serial-USB chip.
The other chip is presumably an optocoupler, but the vendor/model is unknown.
