Table 1	Audio Electrical Specifications
	Microphone	-73 dB

*To convert from dB to number of significant bits, use the formula:

n=	⎛	dB	≈	dB⎞
	⎝	-[---20------log---------10------]-		--6----	⎠

For example, for 61dB S/N then n=61/6 or approx. 10 significant bits, or in other words, about 6 bits of noise.

Keyboard Connectors

PS/2 Keyboard and Mouse Connectors

The PS/2 connectors provide an interface for a keyboard and a mouse to the system. Consult the documentation that accompanies each input device for specific information concerning its use.

HP Parallel I/O Connector

The 25-pin HP Parallel I/O interface uses Centronics interface protocols to support peripheral devices such as printers and plotters. Consult the docu- mentation that accompanies each peripheral device for specific information concerning its use.

802.3 Network Connectors

Your workstation has built-in LAN-AUI and LAN-TP (Twisted Pair) con- nectors for the 802.3 (ETHERNET) network. Connections to ThinLAN net- works require an external transceiver. Your workstation will autoselect the correct network setting. The Models B132L+/B180L allow you to also manu- ally select your LAN configuration.

NOTE:Only one of the network connectors can be used at one time.
