Echo characters received from serial port
Change or disable GPIB end-of-string termination mode
Place the GP485 serial port online/offline
Ignore serial port errors
Change serial port parameters
Set conditions for asserting SRQ
Return GP485 status
Change serial port Xon/Xoff protocol
Use in a debugging environment, when a terminal is connected to the GP485
instead of serial device. Data that the GP485 would send to the power-supply
is displayed on the terminal screen. User can also write characters on the
terminal to send to the GP485.
bool= 0 echo off
* call echo without argument, returns it’s current status.
* echo is disabled by default.
* echo remains in effect until echo called again, call nl or turn off the GP485.
Example:
1. WRT$=”echo 1”+CHR$(13)
2. WRT$=”echo”+CHR$(13)
Use
the data string sent by the serial device when the string contains the specified
end-of-string character.
eos
address and is sending serial data to the GPIB.
X,B - set
when sending data from the power-supply.
D - EOS mode disable.
* EOS mode is diabled by default.
* call
* The assignment made by this function remains in effect until
Example:
1. WRT$=”EOS X,B,10”+CHR$(13)
2. WRT$=”eos”+CHR$(13)
Note: The Zup power supply series default termination is <LF> therefore
again, call nl or turn off the GP485.
