Installation and Setup

2. Locate the I/O port on the rear panel of the ATD/TD.

3. Connect the white wire of the cable assembly (P/N

N610-0402) to the Start - Normally Open (Pin #5).

4. Connect one of the black wires to the Ground (Pin #12).

5. Connect the red wire to the Ready In (Pin #9).

6. Connect the remaining black wire to the Start -

Normally Open. (Pin #6)

The HP 6890 GC cannot accept BCD signals from any external

samplers including PerkinElmer samplers. There is no cable or

procedure available to accomplish this.

7. Connect the 9-pin connector on the cable (P/N N610-

0402) to the Remote Start - Stop connector (port #3) on

the rear panel of the HP6890.

NOTE: You can use either port #3 or port #6 since they are wired in

parallel with each other.

8. If the HP6890 is prepared and ready to start a run,

placing a contact closure (shorting) across the white

wire and either one of the black wires will start the run.

9. The open collector output from the red wire to either one

of the black wires simulates the GC Ready Output

relay's Normally Open position with respect to Common

at the black wire. Use the red wire as the Ready Output

relay's Normally Open position and use the black wire

as the Ready Output relay's Common position.

10. When the HP6890 is Ready to begin the next run, the

Red wire will be effectively shorted to the black wire

(ground) through the transistor's collector-emitter

junction.
