User guide
•  Grouping of receptacles — To support dual powered devices by controlling them 
simultaneously, two or more receptacles can be grouped together. Grouping and 
ungrouping can be done via the front panel, TCP ports using Simple Instruction Set 
(SIS™) commands, or the internal web pages.
•  Detection device (alarm relay) — This relay on the rear panel can be connected to a 
relay-controllable siren or other detection device, and can be programmed to react at 
specified power level thresholds. The alarm relay can be configured for either normally 
open or normally closed state, which activates the attached alarm device when power 
drops or increases beyond a specied amount. E-mail messages can be generated based 
on alarm relay conditions.
•  Internet communication — The PCS4 uses standard Ethernet and TCP/IP 
communication protocols, including ARP (Address Resolution Protocol), DHCP (dynamic 
host configuration protocol), TCP/IP (Transmission Control Protocol/Internet Protocol), 
Telnet, and HyperText Transfer Protocol (HTTP). 
•  Embedded web page serving — The IPL T PCS4 has 900 kB of internal ash memory 
for storing user-customizable web pages and configuration settings. Nonproprietary 
programming (HTML and JavaScript™) is available, as well as other programming 
methods.
•  Security — Built-in multilevel security provides user control over access to devices 
attached to the PCS4. Appropriate security is provided by password protection for 
Administrator and User levels.
•  Mounting — The PCS4 can be placed on a tabletop (four rubber feet are provided 
and can be attached). Optional hardware for mounting the unit under a desktop or 
podium or on a rack shelf is not included, but can be ordered separately (see “Optional 
Accessories” in the “Reference Material” section to order rack mounting kits).
