162 kHz. Its waves can be picked up as far as 2,500 to 3,500 km away from Allouis. NeoClock consists of a plastic case (desk version in a blue ABS casing or industrial version in a polycarbonate IP67 casing) equipped with a 5-meter serial cable. -

Page 8: Installing The Receiver
2. Connect the cable of the NeoClock receiver to the V24/RS232 serial connector of your system. For the pin assignment, see APPENDIX F TECHNICAL FEATURES). If you want to connect NeoClock to a computer equipped with a standard 9 points SUB-D male connector, you can plug directly NeoClock to this computer. -
Page 9: Receiver Positioning
If this is not the case, go to APPENDIX E TROUBLESHOOTING. 2. Now find a place for your NeoClock receiver. This step is very important to ensure the good reception of the product. Do not fix the NeoClock receiver in any place yet, because you will perhaps have to move and test it in different places to find the best reception of the radio signal. -
Page 10: The Control Leds
The NeoClock receiver is equipped with two control LEDs that indicate the status of the receiver at any time. The operation of these LEDs depends on the system of antennas (DCF77 or France Inter) used by the NeoClock receiver. 6.1.1 DCF77 antenna system... -

(or left LED in front view on the desk version) red blinking: Indicates that the NeoClock receiver has not yet been able to decode the time data coming from the atomic clock since it was powered. Also indicates that the time data coming from the atomic clock could not be decoded without error by the NeoClock receiver for the past 24 hours. - Page 12 Inter transmitter stops to send time data for maintenance reasons. However, you can still obtain a high-precision synchronization of your system during this period by using the NeoClock quartz clock data. Also see § 6.2 IMPORTANT REMARKS for the positioning of the receiver.

Page 13: Important Remarks
6.2 IMPORTANT REMARKS Since it consists of a radio receiver, the NeoClock system must be kept away from any source of electrostatic and electromagnetic disturbances. To ensure correct reception, follow these instructions: To avoid interference, keep the receiver as far away as possible from: •... -

NeoClock for sampling, decoding and saving. In order to guarantee the safety of the data, the NeoClock processor discards any irrelevant data such as hour 27, day 32, month 18, … (these values can actually appear in the case of electromagnetic disturbances, for instance). -
Page 15: For Software Developers
To ensure the safety of the data string: • Do not take into account the time sequence as long as the initialisation bit (byte JS, bit 5) is not set, i.e. the autonomous NeoClock quartz clock has not been synchronised since its last starting. - Page 16 Daylight saving evaluation: No CMOS clock can manage the date of daylight saving. So, be careful with the evaluation of the daylight saving information transmitted by NeoClock as long as the time data transmitted by the system are coming from the NeoClock autonomous quartz clock.

Page 17: Data Transmission
9. DATA TRANSMISSION At the initialisation, NeoClock transmits the time data in binary mode as shown in APPENDIX B table 1. These data are transmitted automatically once a minute: a) In the case of bad reception of the radio signal: at the zero-second shift of the autonomous quartz clock. -
