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.
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 the LAN is being used to change settings, the supply will automatically go to remote with every
command. Stop the LAN program and then press “REM/LOC” button.
- The LAN computer may have sent a Local Lockout command. 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 switch pin1 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
MODE MODE DESCRIPTION
1 LAN Control using an Ethernet connection LAN will disable the J3-IN serial port
2 Local Control using the front panel encoders and
buttons
LAN can be used to measure and read
while in local mode
3 Serial Control using RS-232 and RS-485 through the
J3-IN and J3-OUT connectors
Serial will disable the LAN port
4 Analog Control using an analog signals to the 25-pin
‘J1’ connector
LAN, local or serial may still be used to
measure and set protections
