Communication Troubleshooting
Electrical Characteristics
EIA RS-232-C Section 2.3
For data interchange circuits, the signal shall be considered in the marking
condition when the voltage (V1) interchange circuit measured at the
interface point, is more negative than minus three volts with respect to
Circuit AB (Signal Ground). The signal shall be considered in the spacing
condition when the voltage (V1) is more positive than plus three
volts with respect to circuit AB. The signal state in not uniquely defined
when the voltage (V1) is in this transition region.
EIA RS-232-D Section 2.1.3
For data interchange circuits, the signal shall be considered in the marking
condition when the voltage (V1) on the interchange circuit, measured
at the interface point, is more negative than minus three volts with respect
to Circuit AB (Signal Ground). The signal shall be considered in the spacing
condition when the voltage (V1) is more positive than plus three
volts with respect to circuit AB. The region between plus three volts and minus
three volts is defined as the transition region. The signal state in not
uniquely defined when the voltage (V1) is in this transition region.
During the transmission of data, the marking condition shall be used to
denote the binary state ONE and the spacing condition shall be used to denote
state ZERO.
EIA RS-422-A Section 4.1.1
For either binary state, the magnitude of the differential voltage
(V0) measured between the two generator output terminals shall not
be less than 6.0 volts; nor shall the magnitude of V0a and
V0b measured between the two generator output terminals and
generator circuit ground be more than 6.0 volts.
EIA RS-423-A Section 4.1.1
For either binary state, the magnitude of the voltage (V0)
measured between the generator output terminal and generator circuit ground
shall not be less than 4.0 volts nor more than 6.0 volts. For the opposite
binary state, the polarity of V0 shall be reversed.
EIA RS-449-A Section 2.1.1
The following circuits are classified as Category I circuits: SD, RD, TT,
ST, RT, RS, CS, RR, TR, and DM.
For applications where the signaling rate on the data interchange circuits
(Circuits SD and RD) is 20,000 bits per second or less, the individual Category
I circuits shall use either the balanced electrical characteristics of RS-423,
without the cable termination resistance (Rt), or the unbalanced
electrical characteristics of RS-422-A. Two leads shall be brought out to the
interface connector for each Category I circuit. Each interchange circuit
consists of a pair of wires interconnecting a balanced or unbalanced generator
and a differential receiver.
For applications where the signaling rate on the data interchange circuits
(Circuits SD and RD) is above 20,000 bits per second, all Category I circuits
shall use the balanced electrical characteristics of RS-422. Use of optional
cable termination resistance (Rt) permitted. Each interchange
circuit consists of a pair of wires interconnecting a balanced generator and a
differential receiver.
EIA RS-449-A Section 2.1.2
All other circuits are classified as Category II circuits. For all
applications, Category II circuits shall use the unbalanced electrical
characteristics of RS-423. Each Category II interchange circuit consists of one
wire interconnecting an unbalanced generator and a differential receiver.
