Ethernet connections
The sample manager provides communications using an internal 10/100/1000
megabit Ethernet switch that accommodates the PC (workstation) and as
many as five other Ethernet devices. Connect the shielded Ethernet cables
from each module to the electronic connections on the rear panel of the sample
manager. The sample manager is connected internally to the Ethernet switch.
Requirement: To ensure optimum performance and signal integrity, use only
approved (or Waters supplied), shielded, CAT 5 ethernet cables.

Column heater connection
The sample manager powers and communicates with the column heater. The
external communication cable must be connected to the rear of the column
heater and the sample manager.
To make column heater connections:
1. Ensure the sample manager and the column heater are powered-off.
2. Connect the external communication cable to the High Density (HD)
port on the rear of the column heater.
3. Connect the other end of the external communication cable to the QSPI
port on the rear of the sample manager.
Caution: To avoid damaging electrical parts, never disconnect an
electrical assembly while power is applied to a system module. To
interrupt power to a module, set the power switch to Off, and then
unplug the power cord from the AC outlet. After power is removed,
wait 10 seconds thereafter before you disconnect an assembly.
