Serial Port Connections
In order to communicate to the 232DRIO module it must be connected to an RS-232 serial port. The unit is designed for a baud rate of 9600, so the serial port must be set for this rate. A data format of 8 data bits, 1 stop bit and no parity is used. The 232DRIO is configured as a DCE device (See Table 2.2). If your communications equipment is configured as a DTE device, such as a standard IBM PC serial port, the 232DRIO should be connected using a “straight through” DB-25 cable or a standard DB-9 to DB-25 cable adapter as shown in Table 2.3. If your communications equipment is configured as a DCE device, such as a modem, the 232DRIO should be connected using a “null modem” cable (see Table 2.4).
