We are using the Universal Remote Control (URC) MRX-2 base station to control (RS-232) the HWQS and found that some issue occurred.
In between the MRX-2 and HWQS system, It has a third party RS-232 to Ethernet convertor “Digi one”. After the login process, we can control the dimming system through the RS-232 protocol . However, we found that we cannot control the HWQS system after 10 to 15 minutes, there’re no response of the dimming system.
By using the URC CCP program editor to test the RS-232 command, it has a login request message.
After logging in the HWQS system again, everything run smoothly.
We have repeated the above process several times. We would lost control every 10-15 minutes and login process are requested.
Why the HWQS always request to login?
