8. Test the “remote” PLD module.
Using a terminal emulation program (either
the “HyperTerminal” program supplied with
Windows or another one), test the “remote”
PLD module, as follows:
a) Use the following settings shown to
configure the terminal emulator to
communicate with the “remote” PLD
module:
Data Rate: 9600bps
Data Bits: 8
Stop Bits: 1
Parity: None
Flow Control: None
Connection: Com port
b) Type the word “Connect” (only command
that is not case-sensitive) and press
[Enter]. It will be echoed back on the
screen.
c) When prompted for the (“head” module)
password, enter the word “coral” in all
lowercase and press [Enter].
d) When prompted for the address, press
[Enter], type in the address you assigned to
the “remote” PLD module, and press
[Enter] again.
e) Send a message to the “remote” PLD
module (e.g., by typing something on the
PC keyboard).
f) Observe the LEDs on the front of the
“remote” PLD module while sending the
message. If you installed the jumpers on
the module’s interface, both the TX and
RX LEDs should come on. If you did not
install the jumpers, only the RX LED
should come on.
Repeat Step 8 for the “end” PLD module.
To conduct the tests for a PLD chain config-
ured with external addressing, you will need
the following:
• Three Party Line Data (PLD) Modules and
interfaces
• Three FOCUS chassis connected in a loop
configuration
• One assigned time slot on the FOCUS
T1/E1 line for all three modules
•APC with the FOCUS Configuration
Software (FCS) and your Remote Terminal
Unit (RTU) software installed
•One RS232 cable to connect the PC to the
front of the FOCUS chassis (for configura-
tion) and the PLD “head” module interface
(for testing functionality)
•One or two Remote Terminal Units (RTUs)
to connect to your “remote” and “end”
PLD modules
• One or two RS232 cables modified for
your “remote” and “end” RTUs
To test a PLD chain configured for external
addressing, complete the following steps:
1. Designate the purpose for each PLD
module/FOCUS chassis.
Designate one FOCUS chassis and the PLD
module you are installing in it as the “head.”
Designate the second as the “remote”
module/chassis, and the third as the “end”
module/chassis.
2. Connect the PC to the RS-232 port on the
front of the “head” FOCUS chassis.
(FCS should already be installed and
running.)
3. Bring the FOCUS chassis “on line”.
Click on the “Online” speed button
.
This uploads to the FCS the current status,
settings, operating statistics, etc., for the
FOCUS chassis — and the PLD module.
4. Unlock the FOCUS chassis.
If the chassis is locked, execute the “Unlock
Configuration” command on the FCS Setup
menu or click on the “Unlock FOCUS
Chassis” speed button .
