Input Signals
Modulated IRIG or AFNOR-Codes are applied via the on board SMB connector.
The lead should be shielded. Unmodulated codes are applied at SUB-D connector on
rear panel. Voltages applied to this input shall not exceed 12 V. The IRIG-Code to be
used must be set at the DIP Switch.
Input for unmodulated codes
Unmodulated IRIG-Codes, often referred to as pulse with coded or DC-Level Shift
Codes ( DCLS ), are fed into the board via SUB-D connector on rear panel. Insulation
of this input is done by a opto coupler device. The input circuitry is shown below.
