Note: No other pin positions are present, i.e. only 18 physical pins are on this device.
No pins are present at positions 4, 5, 6, 7, 8, 17, 19, 23 - 37
10
\AA
O
Auto Answer enable indicator, output, active LO, TTL/CMOS.
11
\CTS
O
Clear to Send, output, active LO, TTL/CMOS. A low indicates the
modem is ready to accept data signals for transmission.
12
OH
O
Off-Hook, output, active HI, TTL/CMOS. A high indicates the modem's
hookswitch relay is closed connecting the modem to the telephone line.
13
TXD
I
Serial data input from the DTE (i.e. external UART). A logic "high"
represents a "mark" and a low represents a"space", TTL.
14
\RTS
I
Request to Send, input, active LO, TTL.
15
HS
O
High Speed indicator, output, active LO, TTL/CMOS. Low when
operating at 2400bps rate, high otherwise.
16
\RI
O
Ring Indicator, output, active LO, TTL. When low indicates the
modem is receiving a ring signal.
18
TIP
---
Tip connection to the phone line (RJ11 pin3) from the internal DAA.
20
RING
---
Ring connection to the phone line (RJ11 pin4) from the internal DAA.
Caution: Observe design rules for Tip & Ring trace layout.
21
GND
---
Ground.
22
AMP
---
Audio output to speaker. Function is determined by L & M commands
and the value in register S22. The imput impdedence to the speaker
driver must be greater tha 300 ohms.
38
\DCD
O
Data Carrier Detect, output, active LO, TTL/CMOS. Function is set by
the &C command and the value in register S21.
39
\DSR
O
Data Set Ready, output, active LO, TTL/CMOS. Function is set by the
&S command and the value in register S21.
40
Vcc
---
+5 Volts.
