AVT217 / 1 C

DCF77 signal receiver system from Germany. This signal contains complete information on the date and time as well as possible changes from summer to winter and vice versa. The entire complete signal transmission takes 59 seconds. The receiver is adapted for direct power supply from the computer's RS232 connector. Programs for analyzing the received information from the DCF transmitter and automatically setting the time in the computer can be downloaded from the Internet.

Basic parameters:

• external dimensions (mm) 84 x 22 x 59 (BxHxT)
• supply voltage: with RS232
• current consumption 5mA (5V, RS232)
• signal output DCF77 type OC (gives plus power via resistor 470om) or RS232
• range of working temperatures 0 - 40 ^o C
• tightness class IP 40
• wire markings (power supply from RS232) Red - positive power supply, red screen - mass, white (Gold) - signal, white screen - negative voltage (only to establish the level on TxD)
• system assembled and running

The receiver is used in AVT217 and AVT5022
