SEL-5801 Cable SELECTOR Software
While you can view or modify many relay settings using the front-panel LCD interface, SEL
OGIC
Control Equations to control relay contact outputs must be entered via a relay serial port using a
PC, terminal emulation software, and appropriate communication cable. The relay also supports
communication with other local devices such as modems, port switches, and the SEL-2020/2030.
Communication with these external devices requires appropriate cable. Some of the most
common cables are called out in Figure 1.5. Use the SEL-5801 Cable SEL
ECTOR Software,
available free of charge from SEL, to determine the SEL cable part number to connect with other
specific devices. You can purchase cables from SEL or refer to the cable pinout provided by the
software and build your own.
To obtain your copy of SEL-5801 Cable SEL
ECTOR Software, contact your SEL Representative,
or download it directly from our World Wide Web site at http://www.selinc.com.
