I am considering the purchase of HITEC servomotors HS-79XX series, once the HSR-5980SG/HSR-5498SG models have been discontinued.

My main concern is with the communication interface: the above HSR servos use the HMI protocol that allows the bidirectional serial interface (19200 baud serial-TTL interface).

Could someone confirm if this option (serial TTL interface beyond PWM) is available for the HS-7950TH or the HS-7954SH models?

Thanks,
Filipe
