USB (OPTION) CONNECTION
The USB option can be used for direct communication between the analyzer and a PC;
connect a USB cable between the analyzer and computer USB ports. A USB driver is
required for complete configuration.
Note If this option is installed, the COM2 port cannot be used for anything
other than Multidrop communication.
Configuration: Section 5.4.3.
RS-232 CONNECTION
For RS-232 communications with data terminal equipment (DTE) or with data
communication equipment (DCE) connect either a DB9-female-to-DB9-female cable
(Teledyne API part number WR000077) or a DB9-female-to-DB25-male cable (Option
60A), as applicable, from the analyzer’s rear panel RS-232 port to the device. Adjust the
DCE-DTE switch (Figure 3-4) to select DTE or DCE as appropriate (Section 5.1).
Configuration: Section 4.7.3
IMPORTANT
IMPACT ON READINGS OR DATA
Cables that appear to be compatible because of matching connectors
may incorporate internal wiring that makes the link inoperable. Check
cables acquired from sources other than Teledyne API for pin
assignments (Figure 3-13) before using.
RS-232 COM PORT CONNECTOR PIN-OUTS
Electronically, the difference between the DCE and DTE is the pin assignment of the
Data Receive and Data Transmit functions.
DTE devices receive data on pin 2 and transmit data on pin 3.
DCE devices receive data on pin 3 and transmit data on pin 2.
