Interfacing the MICROCOM DESIGN GTX Modulator to the Campbell Scientific CR1000 Data Logger PRELIMINARY

A subroutine can be developed which can be called periodically to implement the pass

through mode calls in the CRBASIC source code.

Sub SerialThru()

' handle feed through of comport 1 In

GTXInString=""

SerialIn (GTXInString,Com4,1,10,100) 'read in from GTX

'SerialIn (DummyString,Com4,1,10,1) 'read in from GTX

if (GTXInString <> "") then

SerialOut (ComRS232, GTXInString+LF,"",0,0) 'send to PC Util

SerialOut (Com1, "G2C->"+GTXInString+CRLF,"",0,0)

SerialOut (Com1, CRLF,"",0,100)

Endif

' handle feed through of comport 1 In

GTXOutString =""

SerialIn (GTXOutString,ComRs232,1,10,100) 'read in from PC util

if (GTXOutString <> "") then

SerialOut (Com4, GTXOutString,"",0,0)' send to GTX

SerialOut (Com1, "C2G->"+GTXOutString+CRLF,"",0,0)

SerialOut (Com1, CRLF,"",0,100)

endif

EndSub

The code can be called periodically in a program:
