. LEARSJN 6/72 19~ 6-2,-72.

The BDSO is a self-contained asynchronous serial line
interface which can accomodate up to two channels.
It
is directly plug compatible to the I/O Bus system of either
the PDP-8 family (either positive or negative bus), the
PDP-9, or the PDP-9/L. This device expands the machines
communications faculty to accomodate two devices interfacing
with 20 rna current loop or two parallel LA30's (DEC WRITER)
or any combination of each. The BDSO can also interface
EIA-LEVEL operated device such as a high speed asynchronous
modem which meet the requirements of EIA SPEC RS232-C.
The BD50 is full duplex.
Each channel of the BDSO uses two variable clocks: One for
transmitting and the other for receiving. This gives the
user the added capability of transmitting and receiving data
using a wide range of baud rates.
The BD50 uses the program interrupt and skip facilities
of a computer and when used on a PDP-9, has the option of
using API if the PDP-9 is so equipped. Because of the
echo function of the PDP-9, the BDSO can not be used to
replace the console teleprinter.
IOT's on either the PDP-9, PDP-9L or family of 8 are
completely jumper selectable., The lOT codes given are
recommended codes. Any convenient code can be used.

The PDP-9 and PDP-9/L requires hardware echo back

cannot be used with the BDSO as a console teleprinter •.
