Use nl to disable communications between GP485 and serial port or to reset
the GP485 characteristic to it’s default values. Placing the GP485 offline is
like disconnecting it’s serial cable from the serial device.
bool= 0 offline
* GP485 is online by default
* Call onl without an argument returns it’s current status
Example:
1. WRT$=”onl 1”+CHR$(13)
2. WRT$=”ONL 0”+CHR$(13)
Use to ignore or not ignore the occurrence of serial port errors. If not to ignore
the GP485 does not store characters that contain serial errors. Also, the error
is indicated in the serial error code that is returned by the
ignore, the GP485 stores serial port errors in the buffer which are later sent
out of the GPIB port when the serial device is talk addressed. No error serial
code is reported by
errors. The serial port errors include parity, overrun, framing and overflow errors.
bool= 0 don’t ignore serial port errors

Example:
1. WRT$=”spign 0”+CHR$(13)
2. WRT$=”spign 1”+CHR$(13)
Use
characteristics (baud rate, parity, data bits and stop bits) to match the Zup
Possible values:
baud [bits/s]:
parity:
data bits [b/c]:
stop bits:
* default values: 9600 n 8 1.
*
*
Example:
1. WRT$=”spset 1200 n”+CHR$(13)
2. WRT$=”spset”+CHR$(13)
Note: The Zup power supply series data format is no parity, 8 data bits and
power supply.
