I have your PWM Signal Generator SKU:200382, and I am trying to use the serial port control as described in the instruction sheet included with the unit. I am connecting to a Raspberry Pi TTL-UART connection. I can send commands to the PWM Signal Generator (D055) and the duty cycles changes. However, I do not receive back “DOWN” to confirm the setting. Also when I send “read” I do not receive any data. The serial receive line is always 3.3V.

Am I doing something wrong?

Hello,

Are the serial parameters the same? For example, baud rate 9600, data bits 8, stop bits 1.

Best regards.

Sorry, it was a PICNIC problem. (Problem In Chair, Not In Computer) It is working now.
