User Manual – Rev AY AMETEK Programmable PowerMX Series 1144.2.11.1 GPIB/RS232 (incl. USB/LAN) SETUP menuFigure 4-21: GPIB/RS232 SETUP MenuThe GPIB/RS232 SETUP menu may be used to change the interface parameter settings for boththe IEEE-488 interface and the RS232, USB or LAN interface. The number of interfacesavailable 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 asmany 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 onthe same CD ROM as this user manual for more details on using the RS232, USB or LANinterface.The following parameters can be set from this menu:GPIB ADDRESS Sets the IEEE-488 address used by the AC source. Theaddress value can be set from 0 through 31. Address 0 is oftenreserved for the IEEE-488 controller. The factory setting isaddress 1. Once changed, the IEEE-488 address is retained innonvolatile memory.RS232 BAUDRATE This field can be used to set the RS232 baud rate to either9600, 19,200, 38,400, 57600 or 115,200 baud. The baud rateset on the AC source must match the one programmed for thecommunications port of the controller. Baud rates higher than115200 are provided for the USB and LAN interface modesonly. The same setting is used for USB and LAN modes. Foruse with either USB or LAN, the baud rate in this screen mustbe set to 460800. See UTILITY 2 screen for other LAN setupparameters.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 ofdata bits set on the communications port of the controller. ForUSB 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. Thisvalue must match the parity set on the communications port ofthe controller. For USB or LAN use, always use factory settings.RS232 STPBITS This field is used to set the number of stop bits used on theserial port. Available options are 1 or 2 bits. Factory setting is 1stop bit. This value must match the parity set on thecommunications port of the controller. For USB or LAN use,always use factory settings.The number of start bits is always fixed to 1 bit.
