Working with Docklight
Performing the test
A) Creating a new project
Create a new Docklight project by selecting the menu
File > New Project
B) Setting the Communication Options
1. Choose the menu Tools > Project Settings...
2. Choose communication mode Monitoring
Alternative 1 - Using Docklight Monitoring Cable
3.
At Receive Channel 1 , set the COM Port where the monitoring signal from serial
device 1 is received. At Receive Channel 2 , set the COM port for the second
device.
NOTE: In Docklight Monitoring Mode, all received data from one COM port is re-sent
on the TX channel of the opposite COM port ("Data Forwarding"). This does not have
any effect for
Docklight Monitoring Cable setups, since the TX signal is not
connected. But it can be useful for special applications where you need to route the
serial data traffic through Docklight using standard RS232 cabling. If you require a
pure passive monitoring behavior where no TX data appears, you can disable the
"Data Forwarding" using the menu
Tools > Expert Options...
Alternative 2 - Using Docklight Tap
3.
At Receive Channel 1 , open the dropdown list, scroll down to the -- USB Taps --
section and choose the first Tap port, e.g. TAP0 . At Receive Channel 2 , the
second tap port (e.g. TAP1 ) is selected automatically.
4. Set the baud rate and all other communication parameters for the protocol being
used
NOTE: Make sure your PC's serial interfaces port works properly at the baud rate
and for the communication settings used by Device 1 and Device 2. If Device 1 and
2 use a high speed data transfer protocol, the PC's serial interfaces and the
Docklight software itself might be too slow to receive all data properly.
5. Confirm the settings and close the dialog by clicking the OK button.
C) Defining the Receive Sequences used
Define Receive Sequences, which should be marked in the test protocol or trigger an
action within Docklight. Docklight checks for Receive Sequence on both monitoring
channels, i.e. it does not matter whether the sequences come from serial device 1 or
serial device 2.
NOTE: Since a special monitoring cable is used for this test, all communication between
serial device 1 and serial device 2 will remain unbiased and no additional delays will be
introduced by Docklight itself. This is particularly important when using Docklight for
tracking down timing problems. This means, however, that there is no way to influence
the serial communication between the two devices. While communication mode
Monitoring is selected, it is not possible to use Send Sequences.
D) Storing the project
Before running the actual test, it is recommended to store the communication settings
and sequences defined. This is done using the menu
File > Save Project .
