FUNCTION

Power Supply Input 5V

10%.

V+

Internally generated positive supply (+10V nominal).

V-

Internally generated negative supply (-10V nominal).

GND

Ground Lead. Connect to 0V.

C1+

External capacitor (+ terminal) is connected to this lead.

C1-

External capacitor (- terminal) is connected to this lead.

C2+

External capacitor (+ terminal) is connected to this lead.

C2-

External capacitor (- terminal) is connected to this lead.

Transmitter Inputs. These leads accept TTL/CMOS levels. An internal 400k

Transmitter Outputs. These are RS-232 levels (nominally

10V).

Receiver Inputs. These inputs accept RS-232 input levels. An internal 5k

 pull-down resistor to GND is connected to each input.

Receiver Outputs. These are TTL/CMOS levels.
