Figure 4 Connect the ATD/TD to Another GC Using the
Ready/Start Cable
2. The ATD/TD requires a contact closure, or equivalent,
to be applied between pin 9 (Ready In) and Ground
(pins 12, 13 or 14) to receive a GC ready signal. The
ATD/TD provides a contact closure between pin 5 and
pin 6 (Start Out) to start a GC run.
Connecting the ATD/TD to the
HP 5890 and HP 6890
The HP 6890 GC uses one TTL connection for both Start In and
Start Out and uses a second TTL connection for Ready In and Ready
Out.
The HP 6890 GC does not have a Ready Output relay or a Ready
Start relay and, therefore, it needs a special cable kit to communicate
with the ATD/TD (P/N N610-0410). This kit contains the parts
necessary to connect a PerkinElmer sampler to a HP 6890 GC.
To connect the ATD/TD to the HP 6890:
NOTE: This cable contains a resistor, diode, and transistor
contained within the 9-pin connector shell.
1. You must ensure that the HP 6890 GC data file and the
ATD/TD tube number correspond to each other.
