Users Manual

1.Configure the Data Bucket communication parameters, as described in Figure 4-2, for bAUd = 9600, PAR = no, CtS = OFF, and Echo = On.

2.Turn on the PC, start the communications software, and open the COM port configuration screen.

3.Select the following communications parameters Connector COM1 [Typical]

Baud Rate 9600 Data Bits 8 Stop Bits 1 Parity None

Flow ControlNone[May be called the RTS/CTS line]

4.In Terminal, request the Data Bucket to send its identification number by entering: *IDN? <Enter>. If *IDN? did not appear on the screen as the characters were entered, be sure the instrument RS-232 port is configured for Echo = On (Figure 4- 2). If the wrong characters appear, there is an incompatibility in the COM port configurations (baud rate, parity, etc.). If everything seems normal, but characters still don’t appear, check the RS-232 connection cable (see Appendix D). When the RS-232 link is operating correctly, the instrument returns an identification string and execution prompt similar to the following:

FLUKE,2635A,0,Mn.n An.n Dn.n Ln.n =>

Mn.n identifies the main software version.

An.n identifies the analog-to-digital converter software version. Dn.n identifies the display software version.

Ln.n identifies the programmable gate-array configuration version.

5.Other commands can be entered from the PC to gain familiarity with the instrument command set. All commands are summarized in Table 4-4 and explained in Table 4- 5.

For example: to reset the instrument, configure channel 0 to measure volts dc using the 300V DC scale (scale 4), send scan results to the RS-232 port, and scan once, enter the following:

*RST [Resets the instrument (which does not affect the communication parameters)] =>

FUNC 0, VDC, 4 [Set channel 0 to volts dc and scale 4 (300V DC)] =>

PRINT_TYPE 0,0 [Sets the data destination as the RS-232 port, and all data] =>

PRINT 1 [Enables data logging to the RS-232 port]*TRG [Triggers a single scan] => 15:17:04 07/21/94

0: 000.00 VDC
