The 412C Prom Module is one of the latest additions to the family of Safetran's Prom Modules and is designed to meet or exceed all CALTRANS specifications. Memory map and type of memory devices can be selected through a series ofsoldered jumpers. In addition, the 412C provides extended down time accumulation of up to 72 hours. This is an extension to the 4 hour and 15minute down time accumulator in the 170 controller. Two eight position dip switches mounted on the front panel allow for variable modes of software operation. A lithium battery is supplied for back-up power to the volatile memory devices and the down time accumulator circuitry. Battery is not installed during shipment. A write protect feature, under direct software control, provides additional capability to the 412C PromModule. |
