Configuration 

In line with the versatility of the LinkNet

TM

 Platform, it is possible to re-configure the 

LNKF800 module in the field, either with a 

Personal Computer (PC)

 or via the 

optional 

Control Module

. To use a 

PC

 it is necessary to have a 

Kaval 

CAB000000057 Control Cable

 to connect between the appropriate Module's DB15 

connector on the back of the Card-Cage and the standard DB9 RS232 Connector on 
the PC. On the PC a terminal emulation program such as 

HyperTerminal

 is used to 

communicate to the LinkNet Module. The settings are 9600 baud, 8 bits, no parity, 
and 1 stop bit. Commands are one or two words followed by pressing 

Return

. 

Commands may be given in upper or lower-case. Available commands are... 

ACCESS USER

: 

Required as a simple password to gain access to customer 
settable parameters and diagnostics; This will time-out after 10 
minutes, and may have to be re-typed.

 

HELP or  ?

: 

Displays a list of Available Commands. 

LIST

: 

Displays Current Settings and Status Faults, Etc. 

VER

TXFREQ #########

: 

Displays or Sets the current Transmit Frequency (in Hertz). 

RXFREQ #########

: 

Displays or Sets the current Receive Frequency (in Hertz). 

TXPOWER ###

: 

Displays or Sets the Transmit Power Level (in tenths of a dBm). 

RXTHRESH -####

: 

Displays or Sets the Receive Threshold Level (in tenths of a dBm). 

RXHYSTER ##

: 

Displays or Sets the Receive Hysteresis (in tenths of a dB). 

TIMEOUT ####

: 

Displays or Sets the Timeout-Timer value (in Seconds). 

TESTOSC 1 or 0

: 

Enables or Disables the Test Oscillator.
