6 Configuring the RMC using PCCU32 software
IMPORTANT NOTE: PCCU32 version 7.57 software or newer is
required to communicate with the RMC equipment for configuration.
Previous versions of PCCU32 are not compatible. It is assumed that
PCCU32 is already installed in the PC or laptop used to connect to the
controller. To download the latest PCCU32 version, see the Additional
Information section. For PCCU32 installation instructions, see the
RMC100 User Manual.
6.1 Establishing local communication
Local communication between a host system (laptop or PC) and the RMC can be
established by a direct USB connection.
The following instructions are for a USB port connection. For other ports, refer to the
RMC user manual.
The required USB cable has a USB 2.0 Type B plug to a USB 2.0 Type A plug.
To set up local communication using the USB port:
1. Power on the RMC and laptop.
2. Connect the USB cable. An annunciator in the LCD displays a lower case "u" for
local USB connection.
3. Start PCCU.
