BBG EDI LCS-300 User Manual

1. Overview
The LCS-300 is a LORAN C signal generator capable of simulating a LORAN chain with a master and
two slave stations. The signal characteristics are controlled from any ASCII terminal via the RS-232
link. The GRI, slave TD's, and amplitude of the pulse groups can be set. These settings can be stored
in eeprom to be recalled on power-up.
2. Setup
To prepare the LCS-300 for operation you must connect the power supply and a terminal operating
at 9600 baud, 8 bits, no parity and no handshake.
2.1. Power Supply
Any power supply providing 9 VDC at 200 mA can be used to power the LCS-300. The plug is a
standard 2.5mm power connector with the center pin positive. The input voltage must be
between 7 and 15 VDC.
2.2. Terminal
Microsoft HyperTerm, the supplied LCS-300_terminal.exe, or any terminal program supporting
RS232 can be used. Set the parameters to 9600,8,N,1 with no handshake and connect the
terminal to the DB9 connector on the rear panel using a standard 9-pin serial cable. Note that
the LCS-300_terminal.exe is configured with the correct baud rate for the LCS-300.
2.3. Preliminary Test
Send 'enter' (0x0D) to clear the buffer in the LCS-300, then send a lower case 'i'. Do this by
typing 'i' followed by enter. The current settings for the GRI, TD's, and amplitudes will be listed
on the terminal screen.
2.4. LORAN Connection
Connect a LORAN receiver to the connector on the lower left of the front panel labeled
"Composite Loran C Output." The LCS-300 can be connected directly to the LORAN receiver or
through the LORAN receiver's antenna coupler. Read the next section to learn how to set the
GRI, etc. to the required values.
3. Controlling the LCS-300
3.1. Command Structure
Commands are one or two letters followed by a numeric value. No spaces are used. All
commands must be followed by the 'enter' key. For instance, to set TD1 to a delay of 27.1234
uSec, type 'x271234' followed by the 'enter' key. Commands are case sensitive, an uppercase 'X'
will set the amplitude for TD1 not the delay.
