 +
 +===== Description =====
 +The implementation of a special fastClock command in mergCBus will also need a display to make it visible.\\
 +The basic idea was using four bcd-to-7-segment chips, and connect it to any CAN-GC2.\\
 +But with all the resistors and other necessaties,​ the pcb board was growing out of proportion.\\
 +By using a PIC processor,​several more options became available.\\
 +CAN-GC7 is now direct linked into the CAN-GC network, and will also work in standard mergCBUS system.
 + 
 +
 + \\
 +
 +===== Features =====
 + * Displays date and time in interval\\
 + * Displays weekdays with 7 individual leds\\
 + * Connection ready for mergCBUS and CAN-CGx\\
 + * On-board selectable for 5 or 12V mergCBUS\\
 + * Intensity adjustable via Rocrail\\
 + * Low power consumption\\
 + * Cheap displays used\\
 + 
 +
 +===== Perfect pc-board and/or kits available =====
 +^ The board with week day LEDs and common anode displays. ^^

 +===== Setup =====
 +The FLiM button is PB1 connected to RB4.\\
 +On FLiM mode the display will go off and only the upper separator point will illuminate.\\

 +===== Connection cable =====
 +Cable connections are explained on [[:​can-gca1-en#​connection cable|this page ]]
 +
 +In addition to the standard CAN-GCx connections with D-Type connectors, the 4 standard screw-terminals are available like in mergCBUS.\\
 +The function of each terminal is printed on PC-board and is like this:\\
 +1. +12 V or + 5 V (selectable)\\
 +2. CANL\\
 +3. CANH\\
 +4. Ground\\
