3.10 Remote Control Interfaces
Setup and connection information on setting up remote control using either GPIB, RS232, USB
or LAN interfaces is provided in the Lx/Ls Series II Programming Manual P/N 7004-981. This
manual is distributed on the same CD ROM (P/N CIC496) as this user manual. It can also be
downloaded from the AMETEK Programmable Power website (
www.programmablepower.com ).
Connector pin out information is provided in sections 3.6.6, 3.6.8 and 3.6.9of this manual.
Note: Use of the USB port to control more than one power source from a single PC is
not recommended, as communication may not be reliable. Use GPIB interface for
multiple power source control.
3.11 RPV Input (RPV option)
The –RPV option is factory installed only. If installed, this option disables the internal controller
voltage programming reference. Instead, a user provided DC signal is used to drive all amplifiers.
Note that only one RPV input is available so in three phase modes, all three outputs will track the
same RPV DC input signal.
A 0 to +10 VDC signal will provide a 0 to full-scale voltage output on the selected voltage range.
To enable the RPV mode, press the MENU key until the CONTROL screen and scroll to the ALC
setting entry. If the ALC is set to REG or ON, turn if OFF first. Then scroll to the VOLT REF entry.
Select EXT to use the RPV (remote programming voltage).
The presence of the RPV option is indicated by the –RPV field in the model number on the serial
tag. Note that the –EXT and –RPV options are mutually exclusive so only one or the other can be
present.
