Introduction and Specifications
Getting Started
Establishing
Communication
The SEL-787 base model has two EIA-232 serial communications ports. The
following steps require PC terminal emulation software and an SEL Cable
C234A (or equivalent) to connect the SEL-787 to the PC. See Section 7:
Communications for further information on serial communications
connections and the required cable pinout.
Step 1. Connect the PC and the SEL-787 using the serial
communications cable.
Step 2. Apply power to both the PC and the relay.
Step 3. Start the PC terminal emulation program.
Step 4. Set the PC terminal emulation program to the communications
port settings listed in the Default Value column of Table 1.1.
Also, set the terminal program to emulate either VT100 or
VT52 terminals.
Step 5. Press the <Enter> key on the PC keyboard to check the
communications link.
You will see the
= prompt at the left side of the computer
screen.
If you do not see the
= prompt, check the cable connections,
and confirm that the settings in the terminal emulation program
are the default values in Table 1.1.
Step 6. Type QUIT <Enter> to view the relay response header.
You will see a computer screen display similar to Figure 1.1. If
you see jumbled characters, change the terminal emulation type
in the PC terminal emulation program.
Step 7. Type ACC <Enter> and the appropriate password (see
Table 7.33 for factory default passwords) to go to Access
Level 1.
=>QUIT <Enter>
