Standby Mode (And Display Brightness); Memory Card (Sd-Card); Usb Connection To The Pel; Lan Ethernet Connection To The Pel - AEMC PEL 102 User Manual

■
When the instrument is not powered by AC power and no recording is pending or in progress, it can be turned
OFF with the ON/OFF button (see § 3.3.2).

3.5.2 Standby Mode (and Display Brightness)

When the instrument is ON and there is no activity for a definite time period, the LCD (PEL 103) automatically goes into
Standby mode.
The measurements and recording stay active, but the LCD backlight brightness diminishes to a user preset level. The
Standby LCD brightness level is user programmed through the PEL Control Panel (see § 4.4.1).
To re-establish the LCD Brightness, press the Enter or Navigation buttons.
Note that the overall display brightness is also programmed through the PEL Control Panel (see § 4.4.1).

3.5.3 Memory Card (SD-Card)

The PEL 102 and PEL 103 use an SD card for data storage. SD-Cards (up to 2 GB) and SDHC-Cards (4 GB up to 32 GB)
formatted FAT32 are supported. The PEL is delivered with a formatted SD card in the instrument. If you want to install a
new SD card, you must format the card before use.
■
Formatting the SD-Card is possible through the PEL DataView Control Panel when connected to the instrument
and if no recording is pending or in progress.
■
Hot extraction from the PEL is possible when no recording is in progress.
■
PEL files use short names (8 characters), such as Ses00004.

3.5.4 USB Connection to the PEL

The PEL 102 and PEL 103 can be connected to a computer through a USB (type A/Type B connectors) to configure the
PEL, prepare a recording session (real-time connection) and download recording sessions.
NOTE: Connecting the USB between the PC and the PEL will not power the logger or recharge the batteries.

3.5.5 LAN Ethernet Connection to the PEL

A LAN connection can be used to view real-time data, instrument status, configure the PEL, setup and start a recording
session and download recorded sessions.
The PEL has an IP address. When configuring the PEL with the PEL Control Panel, if the checkbox next to "Enable DHCP"
is checked in the Communication tab of the Configure Instrument dialog box (see § 4.4.2), the instrument sends a request
to the network DHCP server to automatically obtain an IP address.
If for any reason the DHCP server is not available, after 60 seconds the PEL Control Panel will enter auto-IP mode, using
the default IP address 169.254.0.100 (the same IP address used when "Enable DHCP" is not selected). This auto-IP mode
is compatible with APIPA (Automatic Private IP Addressing). A cross-over cable may be needed in auto-IP mode.
The Internet Protocol used is UDP. Port 3041 is used by default, but it can be modified in the PEL Control Panel (see §
4.4.2) to allow multiple PC connections to multiple PEL instruments behind a router.
Note the LAN parameters cannot be modified while connected over a LAN link. A USB connection must be used to modify
them.
