RS422/485 Serial Connection
The Edgeport/1i supports RS422/RS485 protocol. To configure the features of RS-422/485
communication on the Edgeport/1i, you will short or leave unconnected certain pins at the DB9
connector of the cable. See the following pin assignment:
3
g
TA (T-) transmit data negative
7
g
TB (T+) transmit data positive
8
g
RA (R-) receive data negative
4
g
RB (R+) receive data positive
5
g
signal ground
2
g
no connect
For "jumper wire" based mode configuration, use the following pins:
1
g
full and half duplex
6
g
echo on and off
9
g
line termination
The user can switch on and off the following features:
Line termination (120 ohm)
: To enable the line termination resistor, the user connects pin 9 to
pin 8. To disable line termination, the user leaves pin 9 unconnected.
Full Duplex and Half Duplex
: For Full Duplex operation, pin 1 is left unconnected. For Half
Duplex operation, the user shorts pin 1 to pin 5 (GND) at the cable connector.
Echo On and Echo Off
: For Echo On mode, pin 6 is left unconnected. For Echo Off mode, the
user shorts pin 6 to pin 5 (GND) at the cable connector.
If the drivers are not already installed, go to "Edgeport Driver Installation” starting on page 8.
