1 xflashing = Check network connection
The LAN-Modem is not receiving a link pulse from
a hub. Check the cable and hub.
2 x fhashing = Check serial basic configuration
Use the Telnet configuration to check the basic
settings of the LAN-Modem for Port 0:
SETUP Port 0 (serial) r UART Setup r Baud = 57600
SETUP Port 0 (serial) r UART Setup r Parity = NONE
SETUP Port 0 (serial) r UART Setup r Data Bits = 8
3 x flashing = Check serial basic configuration
Use the Telnet configuration to check the basic
settings of the LAN-Modem for Port 0:
SETUP Port 0 (serial)

r
Handshake = HARDWARE
All LEDs on = Self-test error
