PIN OUT FUNCTION TABLES BY MODEL NUMBER
The following tables detail pin out functions by the DDC model
number.
The RDC-19220S has differential inputs but requires both ±5 V
power supplies.
The RDC-19222S has differential inputs and can be used with
+5 V only.

Note:
When using the built-in -5 V inverter: connect pin 2
to 26, pin 17 to 22, and a 10 F/10 Vdc capacitor
from pin 23 (negative terminal) to pin 25 (positive
terminal). Connect a 47 F/10 Vdc capacitor from
-5 V to GND. The current drain from the +5 V supply
doubles. No external -5 V supply is needed.
