1.5.10 Asynchronous Serial Communications: COM1, COM2 (J1, J2, J5)
The CA386-N1 has two serial ports: 1 RS232 and 1 RS232 or RS485. One is connected to a female DB9 connec-
tor (J5). Both are accessible via header connectors (J1, J2). J1 and J2 are designed to connect directly via a 10-
pin ribbon-cable to a DB9 connector. Figure 1.8 shows the pin-outs for these connectors with COM1 configured
for RS232.
