High Reliability

Considering the unstable industrial sites, preventive measures against electrical shocks such as external overvoltage are applied and reliable components are used to simultaneously provide high reliability and performance.

Auto RTS Control (Auto Toggling)

The Systembase BASSO-1010DS has a built-in hardware feature that performs automatic toggling to prevent devices from sending data simultaneously. This operation is crucial when multiple devices are connected to prevent electrical collisions that lead to errors and unstable communications.
