4.2.11.1  GPIB/RS232 (incl. USB/LAN) SETUP menu 
 
Figure 4-22: GPIB/RS232 SETUP Menu 
The GPIB/RS232 SETUP menu may be used to change the interface parameter 
settings for both the IEEE-488 interface and the RS232, USB, or LAN interface. 
The number of interfaces available will depend on the specific model and options 
as well as the time of manufacture.  Older MX models do not offer USB or LAN 
interfaces.  Newer models can be equipped with as many as 4 different 
interfaces although only one can be used at the same time. 
Refer to the MX Series Programming Manual P/N 7003-961 distributed in Adobe 
PDF format on the same CD ROM as this user manual for more details on using 
the RS232, USB or LAN interface. 
The following parameters can be set from this menu: 
GPIB ADDRESS  Sets the IEEE-488 address used by the AC source. The 
address value can be set from 0 through 31. Address 0 
is often reserved for the IEEE-488 controller. The 
factory setting is address 1. Once changed, the IEEE-
488 address is retained in nonvolatile memory. 
RS232 BAUDRATE  This field can be used to set the RS232 baud rate to 
either 9600, 19,200, 38,400, 57600 or 115,200 baud. 
The baud rate set on the AC source must match the one 
programmed for the communications port of the 
controller. Baud rates higher than 115200 are provided 
for the USB and LAN interface modes only. The same 
setting is used for USB and LAN modes. For use with 
either USB or LAN, the baud rate in this screen must be 
set to 460800. See UTILITY 2 screen for other LAN 
setup parameters. 
RS232 DATA  This field is used to set the number of data bits to 
either 7 or 8. Factory setting is 8 bits. This value must 
match the number of data bits set on the 
communications port of the controller. For USB or LAN 
use, always use factory settings. 
RS232 PARITY  This field is used to set the parity. Available options are 
Even (E), Odd (O) or no parity (N). Factory setting is 
No parity. This value must match the parity set on the 
communications port of the controller. For USB or LAN 
use, always use factory settings.
