2.2.1.2 Connecting the Serial Communication Cable
The Multi-Channel Online Monitor must be powered off prior to connecting or disconnecting any cables
from the top or rear communication panels. Connecting or disconnecting cables with the power on may
cause software and/or communication errors with the Multi-Channel Online Monitor and 2900 Series
Analyzer.
1. Connect one end of the serial cable (9-pin connector) to the YSI 2900 Series 9-pin RS-232 serial
communication port
located on the rear panel of the analyzer (Figure 2-2). Fasten the connector securely with the
two connector thumbscrews.
