Connecting More than One Head
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).
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.

Selecting Channels
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.
