This chapter provides instructions for working with multiple heads and channels 
from various connected devices. Topics include:

It is possible to attach more than one Ophir head to the PC in one of two ways: 
by using several single channel devices (USBI, Pulsar-1 and Quasar), or by using 
multiple channel devices (Pulsar-4 and Pulsar-2).  

In the case of single channel USB devices (USBI, Pulsar-1) each device connects 
between one head and the PC. Multiple USB devices can be attached to the PC 
by using more than one USB port. Most PCs are equipped with between 2 and 6 
USB ports. However, the USB standard specifies that up to 127 devices can be 
attached to one USB controller. The standard therefore defines a device called a 
hub. Hubs provide ports to allow multiple devices to be attached. The USBI 
device requires a hub that can provide power to downstream high-power devices. 
The Pulsar-4 (and Pulsar-2 and Pulsar-1) do not require power from the hub, but 
require a High Speed (USB 2.0 compliant) hub for optimum performance.  

In the case of the Quasar device, a single Bluetooth radio adapter attached to the 
PC can connect to at least four Quasar devices at once. Operation with more than 
one radio device attached to the PC is not supported. 

Using a multiple channel device (Pulsar-4 or Pulsar-2) up to four heads can be 
attached to the PC using a single device. Multiple heads can also be attached 
using a combination of these two methods.  

The StarLab application allows you to work with multiple channels from various 
devices at the same time. The devices may be connected to many types of heads 
including thermopile, photodiode, pyroelectric or a combination of different head 
types. In addition to being able to connect the application to numerous channels 
at once, you can specify which of the connected channels you wish to view.
