ECTION NTRODUCTION
Before the existence of SPE, technicians were required to be on site to monitor or
configure a module within the KTS and only one module could be configured at a
time. With the SPE(M)-U( ) ETU, technicians can launch multiple applications on a
remote laptop and monitor or configure multiple modules concurrently in the KTS.
This is done through the creation of Virtual COM ports within the SPE application.
The SPE Application is required for any application to communicate with the SPE
module as it performs the necessary encapsulation (virtualization) of the data that is
sent out from a technician's laptop. This encapsulation uses a custom, serial-like
protocol (in the case of a serial connection), that is initiated and terminated between
the SPE Application and the SPE ETU module; no other application or module will
recognize the data.
The general concept is as follows for Serial communication to the SPE(M)-U( ) ETU in
the KTS:

Select the physical COM port (e.g. COM1) that is normally used for serial
communication to the KTS. When this is done, the transport method is serial.
Superimposed on the transport medium (physical COM port) is a series of
Virtual COM ports (COM 4, COM50~54).
COM50~53 are mapped to COMA~D on the SPE module, so:
