Overview
This document describes how to set up and use the Dynamic Environment Emulation (DEE)
triggered play function to synchronize two Vertex®channel emulators to play DEE in
synchronization mode. This document also provides a Ruby script example for triggered DEE
play on two Vertex units.
Prerequisities
Before performing the procedures in this document, make sure you have:
•2 Vertex units
•2 BNC cables
•Knowledge of Ruby scripting language

Step 1: Connect the Two Vertex Units
In this procedure, you will connect the 2 BNC cables to the rear panel of the primary and
secondary Vertex units. Before performing this procedure, make sure you have 2 BNC cables.
Perform the following steps:
1. Connect one end of a BNC cable to the TRIG2port on the rear panel of the primary Vertex
unit. See Figure 1.
Figure 1. BNC cable connections on rear panel of Vertex units.

2. Connect the other of the BNC cable to the TRIG1port on the rear panel of the secondary
Vertex unit.
3. Connect one end of a BNC cable to the 10 MHz OUT port on the rear panel of the primary
Vertex unit.
4. Connect the other end of the BNC cable to the 10 MHz IN port on the rear panel of the
secondary Vertex unit.
5. Go to the next section to configure the settings on the Vertex units.
Step 2: Configure the Vertex Settings
Before performing this procedure, make sure you have 2 BNC-BNC cables.
Perform the following steps:
1. Access the GUI for the secondary Vertex (192.168.0.162).
2. Access Dynamic Environment Emulation.
The Dynamic Environment Emulation screen appears.
3. Click the DEE File button, and select the DEE file you want to use.
4. Select Triggered Start from the Start Method box as shown in the following figure.
Figure 2. Dynamic Environment Emulation screen.
6. Click the Play button located at the bottom of the window.
The message Waiting for Trigger appears on the left corner of the channel playing bar.
7. Access the GUI for the primary Vertex (192.168.0.161).
8. On the primary Vertex unit, send the following RPI command: TRIGGERONPLAY
9. Access Dynamic Environment Emulation.
The Dynamic Environment Emulation screen appears.
10. Click the DEE File button, and select the DEE file you want to use.
11. Make sure the Start Method box displays Free Play (the default setting).

12. Click the Enable DEE button.
13. Click the Play button located at the bottom of the window.
Both Vertex units begin to play simultaneously.
Ruby Script Example
Refer to the following Ruby script example for triggered DEE play on two Vertex units.
# this is an example script for DEE triggered start
require 'net/telnet'
VERTEX1_address = '172.31.10.2'; #string with Vertex IP address
VERTEX2_address = '172.31.10.3'
Vertex1= Net::Telnet.new("Host" =>VERTEX1_address, "Port" => 3000,
"Timeout" => 240,"Waittime"=> 1, "Prompt"=>/Vertex/)
Vertex2= Net::Telnet.new("Host" =>VERTEX2_address, "Port" => 3000,
"Timeout" => 240,"Waittime"=> 1, "Prompt"=>/Vertex/)
sleep(1)
puts ("Step 1, Load Setup File")
Vertex1.cmd("LOAD D:\\FTPROOT\\SPIRENT\\PUBLIC\\TEST1.SDE");
sleep(30)
Vertex2.cmd("LOAD D:\\FTPROOT\\SPIRENT\\PUBLIC\\TEST2.SDE");
sleep(30)
puts ("Step 2, Load DEE files for both Vertex")
Vertex1.cmd("LOAD D:\\FTPROOT\\SPIRENT\\PUBLIC\\TEST1.vstb");
sleep(2)
Vertex2.cmd("LOAD D:\\FTPROOT\\SPIRENT\\PUBLIC\\TEST2.vstb");
sleep(2)
puts ("Step 3, Set secondary Vertex to Trigger start mode")
Vertex2.cmd("DEE:TYPe:TRIG")
puts ("Step 4, Compile DEE")
Vertex1.cmd("DEE:COMPile:FILE
D:\\FTPROOT\\SPIRENT\\PUBLIC\\TEST1.vstb");
sleep(2)
Vertex2.cmd("DEE:COMPile:FILE
D:\\FTPROOT\\SPIRENT\\PUBLIC\\TEST2.vstb");
sleep(2)
