Communications
Overview
This section lists commands (ASCII and CASCII formats) you can use to com-
municate with the device to obtain information, reports, data, or perform control
functions. You enter all commands on a keyboard when communicating via the
serial port.
Commands, command options, and command variables to enter are shown in
bold. Lowercase italic letters and words in a command represent command vari-
ables that are determined based on the application. Command options appear
with brief explanations about the command function. Refer to the references
listed with the commands for more information on the control function corre-
sponding to the command or examples of the control response to the command.
You can simplify the task of entering commands by shortening any command to
the first three characters; for example, ACCESS becomes ACC. Always send a
carriage return <CR> character or a carriage return character followed by a line
feed character <CR><LF> to execute the command. Usually, most terminals and
terminal programs interpret the Enter key as a <CR>. For example, to send the
ACCESS command, type ACC <Enter>.
Tables in this section show the access level(s) where the command or command
option is available. Access levels in this device are Access Level 0, Access
Level 1, and Access Level 2.

Table 7.1 shows the physical interfaces of the SEL-2414 Transformer Monitor.
Several options are available to provide alternative physical interfaces, including
EIA-485 and fiber-optic cable (see Section 2: Installation for more information
on the interface cards).

Port
Type
Port Interface Usage
Port F
(Serial)
EIA-232 (Nonisolated) Use the EIA-232 port for communications
distances of ≤15 m (50 feet) in low noise
environments.
Port 1A, 1B
(Ethernet)
10/100BASE
-T (Copper)
100BASE-FX (Fiber)
Table 7.6 shows the available Ethernet
protocols. Use Telnet to emulate serial
communications in a network environment.
Port 2
(Serial)
a
ST fiber Use the fiber-optic port for safety (electrical
isolation) and large (500 m to 4 km)
communications distances with an SEL-2812.
