Signal Name and Description

 

 

P2

J11

Mnemonic

 

 

 

 

 

 

 

 

 

 

 

A23

46

RXD4

RECEIVE DATA (serial port 4) - data that is

 

 

 

demodulated from the receive line is presented to the

 

 

 

terminal by the modem.

 

 

 

 

C24

47

GND

GROUND

 

 

 

 

A24

48

RTS4

REQUEST TO SEND (serial port 4) - RTS is supplied

 

 

 

by the terminal to the modem when it is required to

 

 

 

transmit a message. With RTS off, the modem carrier

 

 

 

remains off. When RTS is turned on, the modem

 

 

 

immediately turns on the carrier.

 

 

 

 

C25

49

GND

GROUND

 

 

 

 

A25

50

 

Not used.

 

 

 

 

C26

51

DTR4

DATA TERMINAL READY (serial port 4) - a signal

 

 

 

from the terminal to the modem indicating that the

 

 

 

terminal is ready to send or receive data.

 

 

 

 

A26

52

CTS4

CLEAR TO SEND (serial port 4) - CTS is a function

 

 

 

supplied to the terminal by the modem, and

 

 

 

indicates that it is permissible to begin transmission

 

 

 

of a message. When using a modem, CTS follows the

 

 

 

off-to-on transition of RTS after a time delay.

 

 

 

 

C27

53

GND

GROUND

 

 

 

 

A27

54

DCD4

DATA CARRIER DETECT (serial port 4) - sent by the

 

 

 

modem to the terminal to indicate that a valid carrier

 

 

 

is being received.

 

 

 

 

C28

55

GND

GROUND

 

 

 

 

A28

56

 

Not used.

 

 

 

 

C29

57

GND

GROUND

 

 

 

 

A29

58

TXD2

TRANSMIT DATA (serial port 2) - data to be

 

 

 

transmitted is furnished on this line to the modem

 

 

 

from the terminal.

 

 

 

 

C30

59

GND

GROUND

 

 

 

 

A30

60

RXD2

RECEIVE DATA (serial port 2) - data that is

 

 

 

demodulated from the receive line is presented to the

 

 

 

terminal by the modem.
