Note:
Do not leave a USB to EIA-485 converter connected to Standard Bus without power (i.e., disconnecting the USB
end from the computer while leaving the converter connected on Standard Bus). Disturbance on the Standard
Bus may occur.
Note:
When connecting the USB converter to the PC it is suggested that the Latency Timer be changed from the de-
fault of 16 msec to 1 msec. Failure to make this change may cause communication loss between the PC running
ZE-ZONE Configurator software and the control.
