Fluke 1522 8 Communications Interface

8 Communications Interface

Remote communications allowsan external device, such as a computer, to com-

municatewith the instrument to obtain measurement data and control its opera-

tion. Communication is accomplished with variouscommands issued to the

instrumentthrough the RS-232 serial port.

8.1 RS-232 Connection

The three-conductor jack for the serialport is located on the top of the instru-

ment near the probe connector.One serial cable is included with the instrument.

Additionalor longer cables, of three meters or less, can be constructed by fol-

lowingth e wiring diagram shown in Figure 9.

NOTE:The TxD line on one side connects to the RxD line on the other

and vice-versa.

Toreduce the possibility of electrical interference, the serial cable should be

shieldedwith low resistance between the connector and the shield. It should not

be much longer than isnecessary.
