Table 2 System Overview System Unit Rear Panel Connectors Serial I/O Connectors You can attach a variety of pointing devices (such as a mouse or trackball), or peripheral devices to the Serial Input/Output (SIO) ports on the B132L/ B132L+/B160L/B180L workstation. Peripheral devices include printers, plotters, modems, and scanners. Consult the documentation that accompanies each pointing or peripheral device for specific information concerning its use. The SIO ports are programmable. You can set functions such as bit rate, character length, parity, and stop bits. The SIO ports are used as an interface for serial asynchronous devices to the CPU. The ports operate at up to a 460.8K baud rate. Table 2 shows the SIO connector pin listings. The serial connectors are 9-pin D-sub connectors. Signal names are those specified in the EIA RS-232 standard.
