Trying to connect Cobright DX4 laser to computer using Pyvisa

Question

I am trying to connect a Cobright DX4 laser to my computer to control it from my computer. However I am unable to do so. I have tried using both rm.openresource() and through pyserial. However neither seem to work.

#import visa
import serial
import numpy as np
#rm = visa.ResourceManager() #checks devices that are
rm = visa.ResourceManager('@py') #to take the python backend
#rm = visa.ResourceManager('@sim')

print(rm.list_resources())

inst1 = rm.list_resources() 

    The output is ('ASRL5::INSTR')

However when I query the ID:

inst2 = rm.open_resource("ASRL5::INSTR",read_termination = '\n', write_termination="\r\n")

print(inst2.query("*IDN?"))

I get a timeout error

"VisaIOError: VI_ERROR_TMO (-1073807339): Timeout expired before operation completed."

I have also tried to connect using pyserial.

import pyvisa as visa # note the recommended way to import pyvisa changed as there is an unrelated visa module
#import visa
import serial
import numpy as np

import serial.tools.list_ports
import sys

list = serial.tools.list_ports.comports()
connected = []
for element in list:
    connected.append(element.device)
print("Connected COM ports: " + str(connected))

if sys.platform.startswith('win'):

    ports = ['COM%s' % (i + 1) for i in range(256)]

        s.close()
        result.append(port)
    except (OSError, serial.SerialException):
        pass
print("Availible COM Ports: " + str(result))

ser = serial.Serial(
    port="COM5", # assumes pyserial 3.x, for 2.x use integer values

    bytesize=8,
    parity="E",  # options are: {N,E,O,S,M}
    stopbits=1,
    timeout=1)

print(ser)

ser.isOpen()

True

Now when I try to send a command eg

ser.write(str.encode('*IDN?'))

5

is the output. I am unsure as to what the issue. I cannot decode having encoded.

Any help appreciated, and sorry for the long post! I have also connected a power meter which worked fine.
