5.1 DeviceNet Digital Interface Setup
Use the following procedure to configure the DeviceNet digital interface on the vacuum system and
obtain a vacuum chamber pressure.
1. Turn OFF power to the Mini-Convectron Gauge Module.
2. Set the MAC ID switches on the Mini-Convectron Module to the correct address position (0 -
63) for the network on which it is installed.
3. Set the data rate switch to the appropriate baud rate setting. See Table 4-5.
4. Connect the DeviceNet network cable to the connector 275 Mini-Convectron Vacuum Gauge
Module.
5. Turn ON power to the DeviceNet connector on the Mini-Convectron Module.
6. See Table 5-1 and Table 5-2 to allocate a connection for the module to the network master. Set
the bit contents to 1 for a Polled connection, and 0 to enable Explicit Messages.
An explicit message connection must be allocated to allow a polled connection to be
allocated. They may be allocated simultaneously as shown in Table 5-1 and Table 5-2.
7. Allocate a connection for the Mini-Convectron Module to the network master as listed in Table
