1

DCD2*

J4-11

Data Carrier Detect 2 – Indicates external serial device is detecting a

 

 

 

carrier signal (i.e., a communication channel is currently open). In

 

 

 

direct connect environments, this input is driven by DTR2 as part of

 

 

 

the DTR2/DSR2 handshake.

2

RXD2

J4-13

Receive Data 2 Input – This line is typically held at a logic 1 (mark)

 

 

 

when no data is being transmitted, and is held “Off” for a brief

 

 

 

interval after an “On” to “Off” transition on the RTS2 line to allow

 

 

 

the transmission to complete.

3

TXD2

JP1-2

Serial Transmit Data 2 Output – The signal on this line comes from

 

 

(J4-15, or

J4-15 or J4-20 thorough the only jumper (JP1) on the I/O Interface

 

 

J4-20)

Board.

 

 

 

TXD2 signal – This signal (J4-15) is available if jumper JP1 on the

 

 

 

I/O Board is set to pins 1-2 (default setting). This line (TXD2) is

 

 

 

typically held to a logic 1 when no data is being sent. Typically, a

 

 

 

logic 0 (On) must be present on RTS1, CTS1, DSR1, and DTR1

 

 

 

before data can be transmitted on this line.

 

TTL

 

TTL signal – This signal (J4-20) is available if jumper JP1 on the

 

 

 

I/O Board is set to pins 2-3.

4

DTR2*

J4-17

Data Terminal Ready 2 – Indicates port is powered, initialized, and

 

 

 

ready. Used as hardware handshake with DSR2 for overall readiness.

5

GND

J4-19

Ground

6

DSR2*

J4-12

Data Set Ready 2 – Indicates external serial device is powered,

 

 

 

initialized, and ready. Used as hardware handshake with DTR2 for

 

 

 

overall readiness to communicate.

7

RTS2*

J4-14

Request To Send 2 – Indicates serial port is ready to transmit data.

 

 

 

Used as hardware handshake with CTS2 for low level flow control.

8

CTS2*

J4-16

Clear To Send 2 – Indicates external serial device is ready to receive

 

 

 

data. Used as hardware handshake with RTS2 for low level flow

 

 

 

control.

9

RI2*

J4-18

Ring Indicator 2 – Indicates external serial device is detecting a ring

 

 

 

condition. Used by software to initiate operations to answer and

 

 

 

open the communications channel.

Notes: The shaded area denotes power or ground. The signals marked with * = Negative true logic.
