Hi, I've installed the Robotiq 2F-140 Gripper to a uFactory xArm 5 Lite in accordance with the guide(s) stated here: 
2. (

Upon powering the arm up, the Robotiq Gripper's LED turns to Blue and Red, then to a steady Red.
When trying to enable the Robotiq Gripper through the xArm studio, the gripper's LED will turn Blue briefly then to Red. A C19 error is then reflected on the xArm studio which is referred to as an end module communication error. I've checked that the xArm's modbus baud rate is at 115200. I've also double-checked the wiring connections and they are correct.

Any help would b greatly appreciated. Thank you.
