Serial Interface Ports
Dual serial interface connectors (COM1 and COM2) are available for
remote control operation. Both serial interface ports are always enabled.
The amplifier will respond to commands from either interface. The last
command received has precedence.
COM1 is an RS-232 only serial interface. No switch settings are required
for COM1. Table 1“, Digital Monitor and Control Connector J1 Pinouts,” on
page 11 lists the pinouts for COM1.
COM2 can be configured as an RS-485 2-wire serial interface or as an
RS-485 4-wire serial interface. The pinouts for the COM2 interface are
listed in Table 1 on page 11, and typical implementations are shown in
Figure 17 and Figure 18.
