Section 4. System Quickstart Table 1. PC200W EZSetup Wizard Example Selections Start the wizard to follow table entries. Screen Name Information Needed COM Port Selection Select the correct PC COM port for the serial connection. Typically, this will be COM1. Other COM numbers are possible, especially when using a USB cable. Leave COM Port Communication Delay at 00 seconds.
