• You want to display figures clear and widely visible?
• You want to use the display board for outdoor use (all weather conditions)?
• For example numerical data as time, speed, width, height, marks, points, weight, price, winning numbers, rates of prices, and so on.
• ALGE display boards have well stood their test in large numbers of pieces and under roughest conditions.

The new generation GAZ4 has the following outstanding features:

• DDirect hook up to ALGE timing units by a two lead data wire or radio
• Manual input from the "Handy Terminal" ALGE COMET (e.g. points, ratings)
• Counter together with ALGE COMET (e.g. for turnstile)
• All purpose application by connecting a RS 232 data output (e.g. from a PC or an electronic scale)
• Operation is possible when charging the display board
• Commutator for three different display-configurations in timing: number / rank, minutes - seconds - 1/100 seconds, hours - minutes - seconds
• Switch to adjust address or special function
• Two or more display boards can be lined up in a row (e.g. one display board for timing and another for number and ranking)
• Up to ten lines can be stacked for a huge ranking display board
• An integrated electronic clock makes it possible to use the display board as a day time clock or as a stop watch (input of time respectively start-stop signal and reset signal with a hand switch)
• Backwards running clock (countdown) to display the time of play (input of time to play and time-out by hand switch)
• Optimal legibility even in direct sunlight
• Long life because of the usage of bistabile seven-segment displays in strong aluminum-frame with Plexiglas plane
• Best running safety because of CMOS technology and quality by ALGE TIMING
• Low power consumption because energy is only needed at the moment of swithing
• Three different ways to supply the display board:
• from a 12 V car battery
• from the mains (PS4 or PP4)
• from internal rechargeable batteries (PP4)
• Operation without an external power supply is possible because of built in powerpack (NiCad rechargeable batteries and net-charging-unit)

Technical Information and facts:

• Electronic system: most modern µP-Technology in CMOS-technique and watch-dog
• Display elements: bistable seven-segment-display, yellow on black ground (little power consumption, best legibility, best running safety)
• Casing: Aluminum case, plastic-covered (black) with pane of Plexiglas for outdoor usage
• Interface: signal compatible to RS 232 (RS 485 is prepared)
• Time basis: quartz oscillator 9.216 MHz
• Operative timing range: -25 to +50°C (-13 to +122 K)
• Power supply:
• Direct supply: 11 to 20 VDC / 2.5 A
• Powersupply PS4: Net device with connection to mains, built into GAZ4

230 V / 50 Hz (or 115 V / 60 Hz)
• Powerpack PP4: Net-charging-device built into GAZ4, external connection to mains, or internal rechargeable NiCad batteries.

external 230 V / 50 Hz (or 115 V / 60 Hz)
Charging time for NiCad: 14 hours

• about m = reading distance in m (DIN 1450)
• about h = running time in h

Display board used as clock (powerpack with fully charged batteries)
* At minus degrees the running time goes down (at -20°C about 20%)

Ordering example: GAZ4 645 + PP4
645 = 6 digits, figure height 45 cm
PP4 = GAZ4 includes a Powerpack PP4
