These parameters can be adjusted using the
Each register (word - 16 bits) of the Modbus RTU protocol is composed of bytes (8 bits) from the Gripper. The first Gripper output Modbus register
2
(0x07D0) is composed from the first Robotiq Gripper bytes (byte 0 and byte 1).

Info
200 Hz is the usual speed when commanding / reading from the Robotiq Gripper. It is therefore recommended to send commands with a
minimum delay of 5 ms between them.
Info
Maximum baud rate of
is 115200 bps.
ACC-ADT-USB-RS485
120 Ohms termination resistor is already present on the converter.
