Introduction

The PASCO CI-6685 BNC Adapter adapts a BNC
connector to a 5-pin DIN connector. The BNC
Adapter allows sensors with BNC connectors to be
used with a PASCO ScienceWorkshop
interface to measure voltages ranging from -10 volts
to +10 volts.

Equipment

INCLUDED

• BNC adapter (CI-6685)

• 2-meter cable with 5-pin DIN connectors

ADDITIONAL REQUIRED

• Any PASCO Science Workshop computer
interface (300, 500, or 700 series for Macintosh or
Windows) or the 6500 series interface for DOS

5-pin DIN connector

W ar ning

Application of electrical voltage in excess of the
values listed in the product specification section
may damage this product, create a safety hazard,
and may endanger the oper-ator. This device
does not use or produce voltages that exceed

42.4 VAC peak, 30 VAC RMS, or 60 VDC.

Connecting a probe’s ground lead
to any potential other than ground
could cause damage to the circuit
being measured, the BNC Adapter,
or the ScienceWorkshop Interface.

Setup Procedure

1. Connect the BNC Adapter to any analog channel

on the ScienceWorkshop computer interface box
with the interface cable (Figure 1a),
or

Insert the DIN plug of the BNC Adapter into the
jack of any analog channel on the
ScienceWorkshop computer interface box (Figure
1b).

Plug into
any analog
channel.

Connect user­supplied probe.

Plug into
any analog
channel.

3. Set up the BNC adapter in the data acquisition

software program (ScienceWorkshop or
DataStudio) as if it were a Voltage Sensor:
Associate the Voltage Sensor icon with the picture
of the analog channel that the BNC Adapter is
plugged into.

About the BNC Adapter

The BNC Adapter allows probes equipped with BNC
connectors (including those sold by Pomona
Electronics) to be used with ScienceWorkshop
interfaces.

The CI-6685 BNC Adapter adapts a probe with a male
BNC connector to a 5-pin DIN style input. The
adapter allows only single-ended measurements (i.e.,
measurements that are ground referenced).

Caution: Connecting a probe’s ground lead to any

potential other than ground could cause damage to the
circuit being measured, the BNC Adapter, or the
ScienceWorkshop Interface.

Mounting on an Experimental Apparatus

1. Use the 1/4–20 threaded screw connector located

on the bottom of the sensor box to secure the BNC
Adapter to an experimental apparatus (Figure 3).
The alignment hole fits over an alignment pin
included on some PASCO apparatuses.
