525 Setup
6.1 Overview
The 525 can easily be interfaced by means of the included 525 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. If the
equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may
be impaired.
6.2 Power
The 525 requires a +5VDC±250mV (
≤470mA) power supply to operate. When the power is supplied from a
computer device, it is recommended that a USB 2.0 port (or greater) is used. The unit may also be powered
directly from a 5VDC USB DC wall-mount supply (
≥470mA). The current draw is highly dependent on the
external loads. If all loads are high impedance, the unit will require far less current to operate correctly. It
should be noted that if 525 consumes
≥500mA, the internal current sense circuit will cause the unit to go into a
latched state, which will be indicated by error beeps . In this state, all outputs will be inactive. In order to clear
this state, the 525 must be power cycled. In order to further avoid this state, it is
highly
recommended that loads
connected to any of the ou
tputs be ≥50 ohms. The USB cable should be plugged into the rear panel of the unit
that is labeled USB. The multi-functional power
button, labeled “Run/Stop,” located on both front and back of
the unit will turn on the 525 when pressed once. If a USB DC wall-mount supply is chosen to be used, it is
recommended that the AC Mains Socket-Outlet be easily accessible so that the external power supply can be
easily removed from the AC Mains Socket Outlet.
6.3 Communication
The 525 provides a standard USB connection for remote communications.
6.4 USB
When the 525 is connected to a remote computer via the USB connection, the computer will recognize the unit
as a USB to Serial Port Adapter. Normally the Windows operating system will automatically install drivers for the
525, but in the event it does not and drivers need to be installed, the following steps can be followed depending
on the version of the operating system . Drivers are included on the provided CD. Once the d rivers have been
installed, the 525 will show up in the device manager as a USB to Serial Port Adapter. The 525 can then be
communicated with by either the included 525 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.

Driver Installation (Windows XP)
1. Plug the 525 into the computer using a USB cable. Make sure the unit is powered on.
2. The computer will display a message indicating it has found new
hardware: “BNC-PG”.
3.
The new hardware wizard will launch. Check the “Install from a list or specific location” option and click
next.
4. S
elect “Search for the best driver in these locations” and check the option to “Include this location in the
search”. Click the browse button and locate the folder on the CD where the 525 drivers are located.
Click next.
5.
A message window will launch asking if you want to continue installing this driver. Select the “Continue
Anyway” button.
6. It should now indicate that it is installing a driver
for a “BNC-PG USB Communications Port”.
7. Once the process is finished, a message will indicate that the drivers have been successfully installed.
8. You can now communicate with the 525 using either the included 525 application or by using any generic
communication terminal program. You can view the Com Port number assigned to the 525 in your
computers device manager under Ports.
