I PRODUCT SHOWCASE I Intelligent nicad battery charger Using a microprocessor-based smart algorithm, the System 90 range of battery chargers, analyse, discharge, charge & condition nicad batteries at the press of a button. The System 90 is suited for batteries used in 2-way radio equipment, cellular phones or video equipment. A liquid crystal display gives information on the capacity and voltage of the pack under test. The System 90 allows testing of up to six batteries at the same time, either of the same type or all different types. Unlike dedicated chargers which can become obsolete as models change, the plug-in adaptor modules of the System 90 will enable new battery models to be charged. New modems have 16-bit processors Netcomm has announced a new range of SmartModems which have 16-bit processing and a surface mount board. This has enabled more features to be included while maintaining the present size. The new design combines V.42 er- Mercury-free batteries from Panasonic Panasonic now has a range of cells which are guaranteed to be free of mercury and thus won't release this noxious metal into the environment at the end of their life.

This includes the soldering and accessory tips, including a hot air tip for heat shrinking, and a small stand. All this goes for $64.95 which is a very good price. Both packages are available from your nearest Jaycar Electronics store. Butane soldering irons at a low price Jaycar has two new butane soldering irons which are selling at an attractive price. If you have not used a butane soldering iron before, you will find that they are very useful and convenient. For example, if you working in the back of a TV set or other confined space where you don't want trailing power cords, they are a boon. For service technicians working on airconditioning control panels or security panels, they are great. They are also very handy to use if you are working on your car - no need to have trailing leads from the battery. By the way, although they use bu- tane (ie, cigarette lighter fluid) as the fuel, they do not have a flame. Instead, the tip itself has a catalytic burner which produces the heat. The iron is adjustable so that you can have the equivalent of an iron rated anywhere between 10W and 60W and a tip temperature up to 400°C - equally handy for those delicate or heavy duty soldering jobs. You can buy this new soldering iron in two packages. First, there is the iron by itself which has a 2.4mm tip and a built-in gas lighter (in the cap). The case is transparent so you can see how much fuel is available and you can refill it quite simply. This unit is priced at just $38.95. Better still, you can go the whole hog and buy the complete carry case Compact soldering station from DSE This new temperature controlled soldering station represents a big saving on conventional soldering stations. It is quite small and is intended mainly for soldering components on PC boards. The soldering iron tip temperature is fixed at 310°C and the power consumption is low - 6W at idle and 12W when the element is continuously energised (eg, during temperature recovery after soldering). The soldering tip has an iron cladding which stops erosion (due to copper being dissolved in the hot solder), so you should seldom need to dress the tip. There is one small point that we think should be fixed and that relates to the exit point of the mains cord ANTRIM TOROIDAL TRANSFORMERS New range of thermistors for transformer protection • Now made in Australia. • Standard range 15VA to 2kVA. • Large ex-stock quantities available. • Competitive pricing available for OEMs & resellers. • Simply the best transformers all round.

Mitsubishi training seminar to be held at Wrest Point The Electronic Technicians Institute of Australia (TETIA) has arranged with Mitsubishi Electric AWA to hold a training seminar at the Wrest Point Hotel Casino. To be held on the 13th and 14th March 1993, the seminar will include sessions on servicing CD players, fax machine theory and servicing, TV and VCR servicing, microwave ovens, and cellular phone theory and practice. Normally, this seminar would only be open to TETIA members from Tasmania but on this occasion it is open to service technicians from all states. According to the organisers , an enquiry to the Taxation Department has indicated that attendance at the seminar is tax deductible as a training expense, including travel, accommodation , meals and registration fees. You will need to check with your accountant on this aspect. For further information on registration and travel arrangements, contact Cliff Townsend, 27 Alma Rd, Orford, Tasmania 7190.

SC IOtech The Personal488/NB is a compact external IEEE 488.2 interface that enables 170 Kbyte/s IEEE 488.22 control of up to fourteen IEEE instruments from a notebook PC via its parallel port. A virtual PC plug-in board in terms of speed and performance, the Personal488/NB is compatible with both IOtech 's DLL driver for Microsoft Windows and with its DOS subroutinestyle and device driver software. The Personal488/NB also supports third-party data acquisition software packages, such as DADiSP and Labtech Notebook. The Personal488/NB uses FPGA (field programmable gate array) technology to permit simultaneous instrument-control and printer transactions via its connection to a notebook PC's parallel port. The unit can draw power from a notebook PC's keyboard port, a 7 to 15 VDC voltage source, or a standard A/ C voltage source via an included power supply. Portable and Remote Applications. As notebook PCs decrease in price and increase in functionality and power, many engineers are finding them practical, easily transportable alternatives to cumbersome desktop PCs. The Personal488/NB enables engineers to use notebook PCs in IEEE instrument control and data acquisition. It is well suited for vehicle testing, such as aircraft and automobile testing, where physical space is at a premium, and is also ideal for users who require a portable computer, such as test-instrument sales engineers, who can now use notebook PCs to demonstrate IEEE 488 instruments on customer calls. The Personal488/NB is also useful for engineers who need to analyse acquired data away from the test site because it enables the same notebook PC to be used both on-site for data acquisition, and in the lab for subsequent data analysis. This eliminates the time-consuming data transfer processes and cross-platform incompatibility problems sometimes associated with using one desktop PC for testing and another for analysis. ::;CIE TIFIC DEVICES AUSTRALIA PTY LTD ~ Melbourne (03) 579 3622 Fax (03) 579 0971 Sydney (02) 344 5200 Fax (02) 349 2602 Adelaide (08) 281 3788 Fax (08) 281 4194 Product names listed are trademarks of their respective manufacturers' company. ]ANUARY 1993 75
