sample. In Slave mode, the GC/MS or data system commands or signals the Tekmar unit to start
processing a sample.
This interface has two cables, Master and Slave control. If you install the Master cable, the unit
will operate in Master mode. If you install the Slave control cable, your system will operate in
Slave. If you are using Revision F or greater HP software, install both cables. Otherwise choose
the mode to use and install the appropriate cable. Use these guidelines:
If your software is not Revision F or greater and you have a cryofocusing module installed in
your system, install the Master cable. Do not install the Slave cable.
If your software is not Revision F or greater and you do not have a cryofocusing module
installed, decide which system suits your needs.
If the total cycle time is shorter than the GC/MS cycle time, install the slave cable. This will insure
the Archon and 3000 are ready when the GC/MS gives the start signal.
If the GC/MS cycle time is shorter than the Archon and 3000, install the master cable. When in
Master mode, be certain the GC/MS is ready when the start signal is given.
Connections:
Master Cable
1. Locate the remote start button on the GC/MS.
2. Locate the Master cable. Note drawing.
3. Connect the Master cable to the receptacle on the rear of the remote start button.
Slave Cable
1. Locate the Molex plug labeled “Accessory Connection” on the rear of the GC/MS.
2. Remove the Molex plug from the remote start button.
3. Locate the Slave cable. Note drawing.
4. If you have Revision F or greater software, attach the two pins, from the Slave cable, to
position 27 and 28 on the Molex plug. It does not matter to which position each pin attaches.
If you do not have Revision F or greater, attach the two pins, from the Slave cable, to position
25 and 26 on the Molex plug. It does not matter to which position each pin attaches.
