3. SELECT THE CONTROL METHOD
3.1. A Variety of Control Methods
The Genesys™ power supply with LAN is very flexible. In addition to the LAN, there are
other ways the supply can be used.
See the Technical Manual for Genesys™ Power Supply for more details on the local (front
panel), serial (RS-232/485), or analog (J1) control.
3.2. LAN, Local, or Serial
The power supply, with the LAN option installed, may be operated through four interfaces.
This section describes how to enable each.
Control using an Ethernet connection
LAN will disable the J3-IN serial port
Control using the front panel encoders and
buttons
LAN can be used to measure and
read while in local mode
Control using RS-232 and RS-485
through the J3-IN and J3-OUT connectors
Serial will disable the LAN port
Control using an analog signals to the
25-pin ‘J1’ connector
LAN, local or serial may still be used
to measure and set protections
3.2.1. Select Local (Front Panel) Mode
The supply may be operated in the local, or front panel, mode even when a computer
is using the LAN connection.
If the supply is in remote mode, the front panel “REM/LOC” LED is ON. The supply
may be returned to local by pressing and releasing the “REM/LOC” button
If the “REM/LOC” button will not go into local mode, then:
If a LAN program is running to change the power supply settings, it will
automatically go to remote with every command. Stop the LAN program and then
press the “REM/LOC” button.
The supply may be set to Local Lockout. Use the LAN to send SYST:SET LOC
(see section 11.4.2) or turn the supply AC off and on and then press the
“REM/LOC” button.
3.2.2. Select RS-232 & RS-485 (Serial) Remote Mode
The serial (RS-232 & RS-485) remote control may be selected even if the LAN option
is installed. The serial remote is described in the Technical Manual for the Genesys™
Power Supply. The LAN has similar capabilities as the serial remote, but the LAN
SCPI programming language is not compatible with the serial language.
To select the RS-232 & RS-485 mode:
A. Switch the supply AC power off.
B. Set the LAN card switches pin1 and 2 to DOWN (see Figure 3).
C. For RS-232, set rear-panel SW1 pin 6 to DOWN.
For RS-485, set SW1 pin 6 to UP.
D. Switch the supply AC power on. The front panel will not show “Lan” at startup.
