2.6.2.1 Making inject-start signal connections
When you are using an Ethernet data system with the 2998 PDA detector, the data system or
controller must receive an inject-start signal from manual injector, to initiate the data-collection and
time-based programs.
The following table summarizes the inject-start connections for different system configurations.
Requirement:
If the injector is an e2695 separations module running in Ethernet mode, then the
inject-start cable must not be connected. However, if the injector is an e2695 separations module
running in IEEE mode, then the inject-start cable must be connected.
2.6.2.2 Connecting to a manual injector
If you are using a manual injector, connect the signal cables from the rear panel connector on the
2998 PDA detector to the injector, as described in the following table.
2.6.3 Connecting to other devices
This section describes signal connections between the 2998 PDA detector’s rear panel and these
devices:
• Waters Alliance Separations Module
• Waters eSAT/IN™ Module
• Waters, or other, manual injector
• Other manufacturers’ integrator or A/D interface device.
Requirement:
To meet the regulatory requirements of immunity from external electrical
disturbances that can affect the performance of this instrument, do not use cables longer than 3
meters (9.8 feet) when you make connections to the I/O connectors. In addition, ensure you
connect the shield of the cable to ground at one instrument only.

Warning:
To avoid electrical shock, power-off the devices being connected before making
any electrical connections.
