3. Set the "Poll Rate" field using the spin arrows. This is selectable in 0.5-second
increments. Poll rates should be relative to the transfer rate. For instance, for baud rate
of 2400, set the poll rate to 1.0 seconds. For a baud rate of 300, set the poll rate at 8.0
seconds.
4. Click the "OK" button.
On the Nanoline controller to be set as the slave controller:
1. Click the "Nanoline... Configuration" menu to open the "nanoLC Configuration" dialog
box. In the "Base Unit" group click the "Configure" button. In the resulting dialog box,
select the same option module as the master controller. Click the "Configure" button in
the "Communication Option Module" group.

The other communication settings can be as desired. However, the baud rate, parity and
stop bits must be the same in both the master and slave controllers. In addition, the slave
controller node must be set to 1. The Watchdog timeout must be slower than the poll rate
set on the master controller.

Real-time clock

NLC-055... base units include a real-time clock as standard. NLC-050... base units
require installation of the RTC option module in Slot 2.
To obtain a real-time clock and other functions, the RTC option module installs in slot 2 (for
more information, refer to "Option modules" on page 14).
When installed, the RTC option module provides date and time retention, data retentive
memory and project storage. The RTC is updated at the top of every hour. If the RTC option
module is not installed, the project is stored on the Nanoline. The date and time can be set
using the Operator Panel but will not be retained if power is removed. In addition, any data
values are not retained when power is removed.
To set the date and time using nanoNavigator software:
1. Connect to the Nanoline base unit using the desired option module (USB, RS485 or
RS232). For more information, refer to the nanoNavigator manual.
2. Click the "nanoLC... Set Date/Time" menu.
This information can be set for a project when not connected to a base unit by clicking the
"nanoLC... Configuration..." menu and clicking the "Configuration" button for the base
unit. From the "Configure Base Unit" dialog box, select the nLC-MOD-RTC option module
in Slot #2 and click the "Configure" button.
