Pin Descriptions
PIN NAME I/O
DESCRIPTION
1 RESET
I Hardware reset pin, Input, active High, TTL. A high on Pin 1 initiates a hardware reset.
An external reset is not required or recommended. The Reset pulse must be a minimum
of 200 milliseconds long.
2 N/C
No Connection
3 RXD
O Received Data, Output, TTL. Serial data output to the host. A logic "high" represents a
"mark" and a logic "low" represents a "space".
9 \DTR
I Data Terminal Ready, Input, active Low, TTL. "&D" sets the function of DTR. The
default, &D2, requires the host to assert DTR to permit a modem link. The modem
drops the call in progress if DTR is revoked and will not connect until DTR is reasserted.
10 \AA
O Auto-Answer, Output, active Low, TTL. A low on \AA indicates the modem is configured
to automatically answer an incoming call.
11 \CTS
O Clear to Send, Output, active LO, TTL/CMOS. This pin indicates the modem is able to
transfer data.
12 OH
O Off-Hook, Output, active High. OH indicates the modem's hookswitch relay is closed.
Hookswitch closure connects the modem to the telephone line.
13 TXD
I Transmit Data, Input, TTL. Serial data input from the host. A logic "high" represents a
"mark" and a low represents a"space", TTL.
14 \RTS
I Request to Send, input, active LO, TTL. The XE9601 does not use RTS.
15 NC
--- No Internal Connection
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. The XE9601 is not
sensitive to the battery voltage polarity across Tip and Ring.
20 RING
— Ring connection to the phone line(RJ11 pin4) from the internal DAA.
