Item Description
1 GPIB Interface : A GPIB interface for connecting remote controller using a computer.
2 Ethernet Interface : An Ethernet interface for connecting remote controller using a
computer.
3 USB Interface : An USB interface for connecting remote controller using a computer.
4 System Bus Interface : Connectors to enable multi-mainframe synchronous operation,
with USB/Ethernet/GPIB/MANUAL control. A System Bus port also for connecting
remote controller.
5 System I/O : Connector with which includes Analog signals: voltage and current
monitor and external wave input, and Digital System Input/Output signals. The Digital
System Input/Output signals are TTL Compatible. The signal is connected to module
with isolation.
6 Fuse : Safe guard against over loading.
7 AC Line : AC power connector that supplies power to all modules in the mainframe.
8 Fan Cooling Air Holes : Air holes with metal fan guard on the rear of the mainframe for
air flow. Fan is on the module and the cooling fan speed automatically increases or
decreases as load power rises or falls in each individual load module.
3.4 Local/Remote Control
Local (front panel) control is in effect immediately after the power is applied. The front panel
keypad and display allow manual control of individual module when Load is used in bench
test applications. Remote control goes into effect as soon as the Mainframe receives a
command via GPIB / Ethernet / USB / System Bus interface. When the remote control is in
effect, only the computer/remote controller can control the Load. The front panel keypad has
no effect except the
LOCAL key. You can return to local control by pressing LOCAL key.
