Splitter Controls...
This splitter drives dual analog current or voltage outputs proportional to a sensor
input signal measurement made by the microBlox® module input ADC. Both
splitter outputs can be scaled/calibrated identically, or you may scale each output
separately. You can even rescale the uB input differently for each output channel.
The third or AUX splitter output is fixed to that of the uB module itself (see module
model specifications). No switches or potentiometers are used to adjust the I/O of
this splitter. Its behavior as an isolated signal splitter is determined via
programmed variables set using a wired USB connection to a host computer or
laptop running a Windows-compatible configuration software program specific to
the splitter model, or using a wired USB OTG (On-The-Go) cable connection to an
Android smartphone or tablet running Agility software. The software provides the
framework for digital control of all configuration and calibration parameters, and
this information is stored in non-volatile memory.
USB Interface
CAUTION:
Do not attempt to
connect USB in a hazardous
environment. Transmitter
should be set up and configured
in a safe environment only.
This splitter includes a USB mini-B socket for temporary connection to a Windows-
based PC/laptop (USB 2.0), or for a wired USB-OTG connection to an Android
smartphone/tablet. The USB interface is used to configure and calibrate the input
of the module plugged into this carrier, and each output of this splitter. Because
the input module, power, and each splitter output are themselves individually
isolated, adding USB isolation is not required for this carrier, except if you are also
wired to the third AUX voltage output of the splitter (which shares common with
the host circuit including USB, and could otherwise be earth grounded by a voltage
monitor tied to AUX

).
Data Rate:
USB v1.1 full-speed only, at 12Mbps. Up to 32K commands per second.
USB 2.0 compatible.
Transient Protection:
Adds voltage protection on USB power & data lines.
Cable Length/Connection Distance
: 5.0meters maximum.
Driver:
No special drivers required. Unit uses built-in USB Human Interface Device
(HID) drivers inherent to the Windows Operating System (Windows 7 or later
versions only).
USB Connector Socket (on Carrier):
5-pin, Mini USB B-type socket, Hirose UX60-
MB-5S8.

Note:
Most Host Personal Computers (except battery powered laptops) will
connect PC earth ground in common to their own USB shield and signal ground.
The third (AUX) output of this splitter shares this common ground and you should
be careful when wired to AUX to not inadvertently add a second earth ground
connection to the host (earth ground should only be applied at one-point in any
isolated circuit).
