5. 9250 Setup
Overview
The 9250 can easily be interfaced by means of the included 9250 application. On standard
models, a USB cable and a port with USB 2.0 capabilities or greater (recommended) are
required to communicate with the unit. Bluetooth is available as an option if wireless
communication is required. If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be impaired.
Power
The 9250 requires a +5VDC ± 250mV (
≥
1.5A) power supply to operate. The included wall
adapter can be used to power the unit. The power adapter should be plugged into the rear panel of
the unit that is labeled 5V
– 1.5A. If a different power source is used, the required mating connector
is a standard, circular female plug with the following dimensions: 5.5mm x 2.1 mm x 9.5mm
(outer diameter x inner diameter x connector length). It is recommended that the AC Mains
Socket-Outlet be easily accessible so that the external power supply can be easily r emoved
from the AC Mains Socket Outlet.
The multi-
functional power button, labeled “Run/Stop,” located on the front of the unit will turn
on the 9250 when pressed once. Since the current consumption is dependent on the external
loads, it is highly recommended that loads connected to any of the outputs be
≥
50 ohms. It
should be noted that if 9250 consumes
≥
1.5A, the internal current sense circuit will cause the
unit to go into a latched state, which is depicted by the flashing LED’s on the Quantum logo.
In this state, all outputs will be inactive. In order to clear this state, the 9250 must be power
cycled.
Communication
The 9250 provides a standard USB connection for remote communications. An optional
Bluetooth feature is also available.
USB
When the 9250 is connected to a remote computer via the USB connection, the computer will
recognize the unit
as a “QC-PG”. Drivers will need to be installed for the remote computer to
interface to the 9250. Drivers are included on the provided CD. Once the drivers have been
installed, the 9250 will show up in the device manager as a USB to Serial Port Adapter. The
9250 can then be communicated with by either the included 9250 application or by using any
generic communication terminal program. The unit is baud rate independent, so any speed can
be selected. Typically a rate of 115,200bps can be used. The minimum suggested baud rate
is 1,200bps.
