Additional Information

General Specifications: Compatible with all MacKay mechanism housings and most competitors’ products. Manufactured under ISO 9001:2000 certified quality processes. Designed to work under in extreme environmental conditions. Can withstand prolonged exposure to intense UV radiation, humidity, rain, sleet, snow and grime and under normal street vibration. Operating temperature range: -40°C (-40°F) to 80°C (176°F). Internal Time Keeping: Equipped with a time-of-day clock that is accurate to a few seconds-per-week. Real Time Clock Accuracy and Count Down Timer Accuracy is certified by an independent laboratory. A 365-day calendar/Real Time clock with short-term power fail backup during battery exchanges/replacement. Time-of-day clock is automatically re-synchronized to the handheld computer's time-of-day clock during data transfer. Perpetual and automatic daylight savings time change feature. Automatically introduce a scheduled profile/rate change. Powered by Patented MacKay SmartPower™ Technology : Supports 6V and 9V alkaline battery packs. Can operate for a period in excess of 12 months1 using a 6V (4xAA) alkaline pack, dual 9V alkaline pack2, or single 9V Lithium pack. Front Display: High contrast and high visibility Liquid Crystal Display (LCD) and Light Emitting Diode (LED) technologies. LCD has programmable time-of-day/duration and LED back light for effective night-time operation. Large display - 2.5cm (1 inch) x 5cm (2 inches). Shows four 1.27cm (1/2 inch) high numeric digits, colon, plus seven additional icon/symbols/messages. Rear Display: Large and highly visible display 2.5cm (1 inch) x 7.5cm (3 inches). Flashes red and silver to indicate 'Time Expired' or solid silver for valid parking time. Can display text “EXPIRED”, “OUT OF ORDER”, two ½” high No Parking Symbols. Optionally supports dual numeric displays (time displayed front and back).3 LED Display: Dual colour (Red/Green) Super Bright LED’s on both front and rear. Flashing LED visible at distance of 24 meters (80 feet) at night. Programmable for maximum flexibility in enforcement options. Patented SmartChute™ Coin Discriminator: 3-coil design provides accurate coin reads and long life. Straight-drop/clear view chute allows for superior detection and removal of foreign objects. Coin chute is easily and quickly replaced/serviced in the field without the need for special tools. Coin chute calibration or chute training is not required. Sorts up to 16 different coin/token signatures and uses a single entrance slot. Can be programmed to detect non-metallic jams such as paper/gum. Validates and discriminates coins electronically by two different coil sensors/methods. Invalid coin indicator on display. Communication and Data Transfer: Supports five (5) modes of communication and programming: IR (infrared); RF (radio frequency); peripheral port; and if card reader installed, card slot, and card adapter port. A typical meter rate or parameter change in less than 10 seconds using IR. Transfer of coin audit data, as well as clock date re-synchronization, in less than 3 seconds using IR. Faster data transfers possible using other communication modes. Coin audit totals are always protected and stored in non-volatile memory. Audit information retained during battery failure and/or replacement. Status of meter uploaded when interrogated or otherwise stimulated. Meter information can be imported into an electronic parking citation issuance system to be printed on a ticket at the time of issuance.4

ISO Card System:4 Programmable to use one (or more) of the following ISO7816 compliant card payment technologies: Microprocessor cards capable of using sophisticated security algorithms to deter fraud. (e.g.DES) Reloadable/reusable type memory card used as a token based stored value card or as a service card to carry out special functions such as simple rate changes, or meter feature changes. Disposable type memory card used as a low cost token based stored value card. Card payment schemes requiring active authentication.4 Card reader rated at 200,000 insertions and constructed for easy maintenance. Special Expansion Features: Two (2) expansion ports, (card reader and main board edge connector), are accessible from within the meter frame. These ports act as integration points for future add-on hardware and accessories. Meter supports an optional button interface located next to coin slot.4 Other custom applications/configurations available upon special request.4 Contact your local representative for further information.
