3.3 DATA PORT CONNECTION
Prior to transferring data, the OM-550 must be connected to a PC with the RS-232
cable assembly supplied with the kit. The cable assembly includes a telephone-style
cable and two adapters. The OM-550 for Windows software supplied with the kit is
used to transfer data through the OM-550 RS-232 Port to a PC for analysis and
storage.
Figure 3-4
The cable is fitted with a 4P4C connector for the Data Port on the OM-550 and a 6P4C
connector for an adapter. The adapters convert 6P4C connectors to 9-pin (or 25-pin)
PC serial-port connectors (DB9 or DB25, female).

To minimize danger to personnel, and to avoid ground loops which could affect
measurement accuracy, never connect the OM-550 to a PC and to the signal
inputs simultaneously!
