Output Option – BCD Series

The BCD output option delivers 5½ digits in BCD (8.4.2.1) form through a 34-pin connector that provides 21 output data lines, data valid, polarity, over-range signals and tri-estate input, plus power inputs to feed the circuit card.

The 34-pin rear connector can be adapted to interface with 37-pin SUB-D terminals by means of a cross-wire adapter supplied with the option.
All the outputs are compatible with TTL and 24V logic and they are opto-isolated with respect to the input signal whenever the card is powered from an external source of 5V or 24V.

BCD option, that can be installed in models ALPHA and BETA, is supplied independently with an instructions manual and the following accessories:

• Adapter for 37-pin SUB-D connector.
• Integrated circuits for changing the logic.
• Instructions manual.
