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 before using.
Received from the factory, the analyzer is set up to emulate a DCE or modem,
with Pin 3 of the DB-9 connector designated for receiving data and Pin 2
designated for sending data..
COM1: RS-232 (fixed) DB-9 male connector
Baud rate: 115200 bits per second (baud)
Data Bits: 8 data bits with 1 stop bit
Parity: None
COM2: RS-232 (configurable to RS 485), DB-9 female connector
Baud rate:19200 bits per second (baud)
Data Bits: 8 data bits with 1 stop bit
Parity: None

The signals from these two connectors are routed from the motherboard via a
wiring harness to two 10-pin connectors on the CPU card, J11 and J12 (Figure
