Solar neutron telescopes (SNT) were designed and installed on high mountains to study particle acceleration mechanisms in solar surface. Of these, SciBar cosmic ray telescope (SciCRT) is a brand new telescope installed on the top of the Sierra Negra volcano in eastern Mexico ($19^{\circ}$N, $97.3^{\circ}$W) composed of roughly 15000 scintillator bars, capable of detecting solar particles with both high efficiency and energy resolution. SciCRT is also useful to study the anisotropy of galactic cosmic ray muons. The implementation of SciCRT as a cosmic ray telescope began on September 2013, with $5/8$ of the complete detector operative. After that, further improvement of the operating conditions on the place were made in order to maintain a stable data acquisition on the severe atmospheric conditions on high mountain (4600 m). In July 2015 we partially upgrade the DAQ system, installing a $10$ times faster readout back-end electronics. The new system was installed only on $1/8$ of the detector and on the top and bottom layers (working as muon detectors and anti-counters for neutrons). The upgrade was motivated by the limited transfer rate of the original DAQ system, designed for an accelerator experiment. With this new system we expect an improvement on the neutron sensitivity of the SciCRT. In this paper we will detail the operation of the new system and analyze the data obtained to evaluate its performance. We will also explain the plans to continue the upgrading process, installing the new DAQ systems on more layers of the telescope and make estimates of the expected future performance of the SciCRT, evaluated through Monte Carlo simulations.
