Digital Interface 11
3.7 Rear Panel
Data Rate Switch The Data Rate Switches select the rate at which data is sent and received on
the DeviceNet network. When the 275
Mini-Convectron Vacuum Gauge
Module power is turned ON or reset by the network, the data rate switch
position will be read by the gauge firmware. Available values are: 125
kbaud, 250 kbaud, 500 kbaud, or PGM. If the gauge power is turned ON
while the Data Rate Switch is in the PGM position, the gauge reads the data
rate from memory.
Node/Address MAC
ID Switches The Node/Address MAC ID Switches sets the media access control identifier
which the network master uses to address the 275
Mini-Convectron Vacuum
Gauge Module. The addresses range from 0 - 63 (00x - 3Fx). The switch
setting is read when power is applied or when the device is reset.
MOD/NET Status
LEDs The Status LEDs indicate whether or not the 275 Mini-Convectron Vacuum
Gauge Module or DeviceNet network has power and is functioning
properly. Refer to Table 3-6 and Table 3-7 for more information.
