Via the rotary encoder switch, all five SPE ports can be individually set as Master or Slave. Any combination of these two modes can thus be configured. The options for Master|Slave auto-detection enable connecting end devices regardless of their setting, the T1-RS51 adapts according to the role as Master or Slave. Two different options are available: With option "Auto 1", the role is re-learned after a link or power-down, similar to the auto-negotiation function in standard Ethernet switches. Option "Auto 2" retains the learned setting per port, even during a link-down. An extremely short link setup is thus possible. This setting is particularly suitable for applications that remain static regarding connected end participants after a one-time learning process.
