of data sets (modems) which are in accordance with
tilis interface; i. e., General Electric TDM 110, 111,
114, 115,
or Bell Series 103 Data Sets. The Termi-
Net
300 Printer can also be used directly coupled if
the
interface specifications are met. Table 1 shows
both the pin numbers and functions on the TermiNet
300 Printer data set connector.
three possible speeds of operation are 10, 15, or
30 characters per second. The corresponding trans-
mission rates for these three character rates are
110 (109.95) baud, 150 baud, or 300 baud.
Each baud rate utilizes a character composed of
one start bit, seven data bits, a parity bit (even
parity), and either one or two stop bits. Two stop
bits are used with lID-baud operation, and one stop
bit is used with 150 and 300 baud operation. See
Fig. 4.
Data transmission speed is variable on the
TernliNet 300 Printer, depending on the position of
the rate selector switch on the control paneL The

Data Terminal Ready Signals data set that TermiNet 300 Terminal is capable of re-
ceiving a call.
(a) Turned off in LOCAL to prevent auto answer by data set
This will initiate disconnect in data set.
(b) Turned off for 67 ms to initiate forced disconnect by data
set upon recognition of DLE EOT. **
