USB (O ) C
PTION ONNECTION
The USB option is for direct communication between the analyzer and a PC; connect a
USB cable between the analyzer and a computer USB port. Baud rates must match:
check the baud rate on either the computer or the instrument and change the other to
match (see Section 6.2.2). This USB connection can only be used when the COM2 port
is not in use except for RS-232 Multidrop communication.
Configuration: Section 6.6
If this option is installed, the rear panel COM2 port cannot be used for anything
other than Multidrop communication.
RS-232 C
ONNECTION
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, Section 1.3), as applicable, from the analyzer‟s RS-232 port to the device. Adjust
the DCE-DTE switch (Figure 3-4) to select DTE or DCE as appropriate (Section 6.1).
Configuration: Section 6.3 and Section 6.7.2 (for Hessen protocol)
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.
