1.4.2 USB Capabilities of the AC source
All AC source functions are programmable over the USB interface. The USB capabilities of the
AC source are listed in Chapter 2 of the User's Manual. Some capabilities support on the GPIB
interface such as ATN, GET and SRQ interrupts do not apply to the USB interface. The USB
interface operates internally at a fixed baudrate of 460800 baud but USB 2.0 burst transfer rates
are supported.
To set up the USB interface on a Windows XP PC, refer to section 3.2
The USB interface may be used to install updated firmware for the Lx / Ls controller if needed.
Firmware updates and a Flash Loader utility program and instructions are available from the
AMETEK Programmable Power website for this purpose.

Multiple USB connections to same PC:
The Windows driver used to interface to the power source‟s USB port emulates a serial com port.
This virtual com port driver is unable to reliable differentiate between multiple units however so the
use of more than one AC power source connected to the same PC via USB is not recommended.
Use of the GPIB interface is recommended for these situations.
1.4.3 LAN Capabilities of the AC source
All AC source functions are programmable over the LAN (Ethernet) interface if the
–LAN option is
installed. The LAN capabilities of the AC source are listed in Chapter 2 of the User's Manual.
Some capabilities support on the GPIB interface such as ATN, GET and SRQ interrupts do not
apply to the LAN interface. The LAN interface operates internally at a fixed baudrate of 460800
baud but autodetection of 10Base-T, 100Base-T and 1000Base-T is supported.
To set up the LAN interface on a Windows XP PC, refer to section 3.3
1.4.4 RS232C Capabilities of the AC source
All AC source functions are programmable over the RS232C interface. The RS232C capabilities
of the AC source are listed in Chapter 2 of the User's Manual. Some capabilities support on the
GPIB interface such as ATN, GET and SRQ interrupts do not apply to the RS232C interface.
Baudrates from 9600 to 115200 are supported.
To set up the RS232C interface, refer to section 3.4
The RS232C interface may be used to install updated firmware for the Lx / Ls controller if needed.
Firmware updates and a Flash Loader utility program and instructions are available from the
AMETEK Programmable Power website for this purpose.
