The LD02 is Tech Edge's new standard wideband AFR/Lambda display unit. The LD02, with digital accuracy (via RS232 connection), replaces the LD01's simpler analogue connection (bypassing the digital - analogue - digital conversion stages). LD02 is field re-programmable and has the potential to be used as a general purpose display for other projects. LD02 is also available as a DIY kit. See some of the other displays we offer. Note : The LD02 comes standard in bright RED which we recommend, or a dimmer GREEN (see below). |
LD02 has two buttons that are used to cycle between possible display modes (top button) and to stop and start on-board logging (bottom button). The LD02 User's Guide describes the current button functionality as this can change from firmware release.
Due to demand, we have made LD02 available in GREEN too. At the moment we have not sourced superbright green LEDs that we are happy with. Therefore we don't recommend the GREEN option as the display is much dimmer, but still usable except when the display is used in bright sunlight. Be aware that the GREEN option may be too dim for dash top applications except when used at night.
Here's another image of LD02 showing the 1.8 m cable and RJ45 connector that goes directly to WBo2's RS232 connector. Note that the cable shipped with units may be black. Click on the image to see the face (zoom).
As with a number of other Tech Edge products, LD02 is also available as a DIY kit that you build yourself. More detailed technical information on how LD02 operates, including schematics, is available on the DIY kit page.
LD02 is a display device for all WBo2 units and was designed to be field re-programmable. This means that bugs can be rectified as well as new features added to the basic firmware. To do this a PC is connected to LD02 using the interface adapter. The FLASH.exe program, running on a PC, downloads new code to LD02. Additionally, various display parameters can be set up with the PC CONF.exe program and these parameters saved to LD02. This and other topics are described in detail in the LD02 User's Guide.
Detail technical information on the digital frame (RS232 data) from WBo2 is available in the WBo2 logger data frames section.
The RJ45/RS232 splitter shown at right is used to connect both a PC and LD02 to a WBo2 unit at the same time. If you already have a splitter and have been using it with an LD01, then the splitter may require simple modifications to now operate with LD02. This is described here.
