1 D Series SERVO Control Protocol
1-1 Protocol
Using D Series Protocol, you can write or read data in the register of the D series SERVO.
1-2 Communication System
D Series SERVO communicates with external device by using Half Line of TTL communication
with only one line as signal line. In case of RS485 SERVO, it communicates with external device
by 2 wire Half Duplex method.
It can send and receive bi-directional communication and it supports both of “Multi-Drop”
which can control several SERVO using only one line and “Single-Drop” which can control
SERVO using a single connection method.
1-3 Test Configuration
It can be controlled by connecting with PC using DPC-11 (TTL) and DPC-485 (SERVO for RS485
communication) provided separately. When the user configures the controller, the user needs
to configure the circuit by referring to the Interface Circuit Diagram below.
(Communication Parameter: Baud rate - 115,200bps, stop bit - 1, parity – none)
⚫ SERVO PINMAP(LEFT) only for RS485 // SERVO PINMAP(RIGHT) for TTL, PWM
⚫ TTL and RS-485 configuration using our products DPC-485, DPC-11
