3.1.4 REMOTE MODE
In Remote Mode the power supply settings are controlled via the IEEE 1118 bus using either a
computer with a Kepco controller or by another MBT unit operating in a remote configuration
with one MBT unit operating as a controller (“G” option enabled) (see PAR. 1.4.2 and Figure 1-
3). MBT Models MG and MGR with the “G” option enabled can also be controlled directly via
either the RS232C or IEEE 488 bus.
PAR. 3.2.2.3 provides instructions for using one MBT keypad to control another MBT power
supply in remote mode. PAR. 3.3 provides instructions for sending remote commands to an
MBT power supply in a computer/controller configuration using SCPI or CIIL programming lan-
guages.
3.2 LOCAL MODE OPERATION
3.2.1 LOCAL MODE CONTROLS AND INDICATORS
Local Mode operation is accomplished using the front panel controls, indicators and keypad
described in the following paragraphs.
3.2.1.1 FRONT PANEL CONTROLS AND INDICATORS.
Table 3-1 lists and describes the function of the front panel controls and indicators; see Figure 2-
1 for the location of operating controls and indicators.
