Tuning the FSK Modem6
It may be necessary to adjust the transmit level, or tune, the L-Series Protocol Converter's internal FSK modem
in order to optimize signal quality. The modem is shipped from the factory with the transmit levels set at
approximately –13 dBm.
The FSK modem transmit level can be adjusted using any PC with terminal emulation software. You do not need
to open the unit case to tune the modem.
To tune the internal FSK modem, follow these steps:
1. Connect a PC to the front panel craft port, using the included DB9-to-DB9 download cable. You must
connect at 1200 baud.
Note: The craft port and the RS-232 port use the same circuit. Connecting to the craft port disables all RS-232
polling on the leg connected to the L-Series Protocol Converter. Before connecting a PC to the craft port,
disconnect the RS-232 connection on the back panel.
2. Connect a level meter or scope across the transmit leads of the FSK modem.
3. Run a terminal emulation program such as Windows™ HyperTerminal.
4. Enter command mode by pressing the Plus key. The CX1 LED on the front panel of the L-Series Protocol
Converter will light green to indicate that the RS-232 carrier is on. The terminal will return the character
"A." Throughout command mode, every valid command is acknowledged by an "A"; if you type an invalid
command, the terminal will return the character "N."
5. Place transmitter on high tone (space) by pressing 4.
6. Use the 1, 2, 6, and 7 keys to bring the transmit level to the desired range. If the level is far too low, use
coarse level up. If it is far too high, use coarse level down. Once the level approaches the proper range, use
the 1 and 2 keys to fine-tune it.
7. When the modem is tuned to your satisfaction, press 5 to turn the transmitter off and the Minus key to exit
command mode.
