Serial I/O Connectors; Serial I/O Pins - HP Visualize b132L Service Handbook

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 func-
tions 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.
