Description
The implementation of a special fastClock command in CANBUS 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 CANBUS system.
Features
* Displays date and time in interval
* Displays weekdays with 7 individual leds
* Connection ready for CANBUS and CAN-CGx
* On-board selectable for 5 or 12V CANBUS
* Intensity adjustable via Rocrail
* Low power consumption
* Cheap displays used
Perfect pc-board and/or kits available

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 this page
In addition to the standard CAN-GCx connections with D-Type connectors, the 4 standard screw-terminals are available like in CANBUS.
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
