Mode of Operation
Transmitters with 4-digit pulse counting function. The module features reset and transmission disable inputs. The accumulated counting value is transmitted in BCD representation on the Dupline. This implies that every digit uses 4 channels. The-digitto-channel allocation is as follows (example with FFD 1680 and FMK C-D plugged in): 100 on highest 4 selected channels (e.g. D5-8). 101 on lower 4 channels of higher group (e.g. D1-4). 102 on higher 4 channels of lower group (e.g. C5-8). 103 on lowest 4 selected channels (e.g. C1-4). For every digit the most significant bit of the BCD equivalent influences the lowest of the 4 allocated channels. Activation of the reset function (pin 3 connected to pin 1) always resets the internal counter to 0, irrespective of the disable and counting inputs. When the transmission disable function is activated (pin 3 connected to pin 5), the transmitter does not transmit its value via the Dupline(R) whereas the internal counter can still operate. A Dupline(R) system can have several FFD 1x80s coded to the same channel groups. In this case the counting values may only be emitted from one transmitter at a time, the other transmitters must be disabled in the meantime. This feature is best obtained by using Dupline(R) receivers with demultiplex output type D 1230 5111 connected to the transmission disable inputs. FK3C 7640 and FL3C 7640 or D 6369 6475 can be used for display of FFD 1680 values. FK3C 7760 and FL3C 7760 can be used for display of FFD 1780 values. Overflow: When the counter reaches 9999 (999999), the transmitter activates all coded channels, thereby causing Dupline(R) displays to become dark. Note: If DC-supplied FFD .... transmitters are used, the length of the supply bus must not exceed 3 m in order to avoid disturbances unbalancing the Dupline(R). Note: Transmitters for numerical signals must not be used in systems where channel generators with 2 or 3 sequences are installed.
