25、 foreword is not part of this Standard) This Standard was formulated under the cognizance of TIA Subcommittee TR- 30.2 on Data Transmission Interfaces. It is intended to be used with ANSI/TIA,EIA-612, Electrical Characteristics for an Interface at Data Signaling Rates up to 52 Mbit/s. Together these

26、 two standards provide for a general purpose DTE-DCE interface for data rates up to a maximum of 52 Mbitis. EIA TIA-bl3 73 3234600 0553079 T28 rn ANSI/TIA-613-1993 1 SCOPE 1.1 Section Abstracts This standard is applicable to the interconnection of data terminal equipment (DTE) and data circuit-termi

27、nating equipment (DCE) employing serial binary data interchange with control information exchanged on separate control circuits. It defines: Section 2 Normative References Section 3 Signal Characteristics Section 4 Interface Mechanical Characteristics Section 5 Functional Description of Interchange

28、Circuits In addition, the standard includes: Section 6 Recommendations and Explanatory Notes 1.2 Application a This standard applies where equipment on one side of the DTE/DCE interface is intended for connection directly to equipment on the other side without additional technical considerations. Ap

29、plications where cable termination, signal waveshaping, interconnection cable distance, and mechanical configurations of the interface must be tailored to meet specific user needs are not precluded but are beyond the scope of this standard. 1.3 Serialization This standard applies to data communicati

30、on systems where the data is bit serialized. No restrictions are placed on the sequence of bits. 1.4 Signaling Rates This standard is applicable for use at data signaling rates up to a maximum limit of 52 Mbitls. 1.5 Synchronous Communication This standard applies to synchronous serial binary data c

31、ommunication systems. TIA-bL3 93 3234600 0553080 7YT = 2 NORMATIVE REFERENCES The following standard contains provisions which, through reference in this text, constitute provisions of this Standard. At the time of publication, the edition indicated was valid. All standards are subject to revision,

32、and parties to agreements based on this Standard are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below. ANSI and TIA maintain registers of currently valid national standards published by them. ANSI/lIA/EIA-612-1993 Electrical Characteristic

33、s For An Interface At Data Signaling Rates Up To 52 Mbit/s TIA-bL3 93 3234600 055LOBL 686 rn ANSI/TIA-613-1993 3 SIGNAL CHARACTERISTICS 3.1 Electrical Characteristics The electrical characteristics of the interchange circuits are specified in ANSITTIAfEIA-612. The meaning of circuit conditions “ON“

34、and “OFF“ for control and timing circuits, and “O“, “I“, “MARK“, and “SPACE“ for data circuits, shall be as defined in ANSI/TIA/EIA-612. 3.2 Protective Ground (Frame Ground) In DTEs and in DCEs, protective ground is a point which is electrically bonded to the equipment frame. It may also be connecte

35、d to external grounds (e.g., through the third wire of the power cord). It should be noted that protective ground (frame ground) is not an interchange circuit in this standard. If bonding of the equipment frames of the DCE and the DTE is necessary, a separate conductor should be used that conforms t

36、o the appropriate national or local electrical codes. Attention is called to the applicable Underwriters Laboratories regulation applying to wire size and color coding. 3.3 Shield In order to facilitate the use of shielded interconnecting cable the interface connector specified in Section 4 provides

37、 a shielded shell for both the male and female connectors. At the DTE the shield is connected directly to the DTE Protective Ground. At the DCE the shield is connected through a network of two capacitors and a resistor as shown in Figure 1. It is recognized that for certain electromagnetic interfere

38、nce (EMI) suppression situations, additional provisions may be necessary but are beyond the scope of this standard. 3.4 Signal Common Proper operation of the interchange circuits requires the presence of a path between the DTE circuit common and the DCE circuit common. This path is obtained by means

39、 of interchange Circuits 102, Signal Commons. Both the DCE and the DTE normally should have their circuit common connected to their protective ground (frame ground) through a resistance of 100 ohms (+20%) having a power dissipation rating of one-half watt. Figure 1 illustrates the signal common and

42、ugable connector signal interface point between the two equipments (see Figure 2). A 50-position connector is the connector specified for all interchange circuits. Figure 3 illustrates the Cable connector which has male (pin) contacts and a female shell (plug connector). Figure 4 illustrates the Equ

43、ipment connector which has female (socket) contacts and a male shell (receptacle connector). Contact numbering is also illustrated in these figures. For all separable connections at the DTE, DCE, or intermediate equipment between the DTE and the DCE; the Equipment connector (Figure 4) shall be used

44、on the equipment and the Cable connector (Figure 3) shall be used on the cable. The cable assemblies will always use the Cable connector (see Figures 2 and 3).
