5 CHAPTER 1: Specifications 1. Specifications Compliance: CE; FCC Part 15 Subpart B Class A, IC Class/classe A Interfaces: EIA/TIA RS-232, DTE or DCE (user-selectable); EIA/TIA RS-422/485 Protocol: As.
6 RS-232 ↔ RS-422/485 CONVER TER (DA T A ONL Y) Temperature Tolerance: Operating: 32 to 122˚F (0 to 50˚C) Storage: –4 to +158˚F (–20 to +70˚C) Humidity Tolerance: Up to 95% noncondensing MTB.
7 CHAPTER 2: Introduction 2. Introduction The RS-232 ↔ RS-422/485 Converter (Data Only) allows your RS-232 and RS-422/485 equipment to communicate with each other. It operates in full-duplex mode over 4-wire lines. A four-wire terminal block on the RS-422/485 port makes installation easy.
8 RS-232 ↔ RS-422/485 CONVER TER (DA T A ONL Y) 3. Configuration Here’s how to configure the RS-232 ↔ RS-422/485 Converter (Data Only) for your application (refer to Figure 3-1 on the next page .
9 CHAPTER 3: Configuration 5. Normally, the Converter’s frame ground is isolated from its RS-232 signal ground. But if you want to connect frame ground to signal ground, you’ll need to solder a 100-ohm, 500-mW resistor to the terminals of location W7.
10 RS-232 ↔ RS-422/485 CONVER TER (DA T A ONL Y) 4. Installation To install your RS-232 ↔ RS-422/485 Converter (Data Only) system, take these steps, making sure that the Converter and your devices are powered OFF: 1. Run an RS-232 cable from your RS-232 device to the Converter’s DB25 female RS-232 port.
11 CHAPTER 5: Operation 5. Operation 5.1 RS-232 Circuitry The RS-232 side of the RS-232 ↔ RS-422/485 Converter (Data Only) is composed of the RS-232 drivers and receivers, the delay circuitry, and other circuitry necessary to operate the RS-232 control lines.

13 CHAPTER 5: Operation 5.2 RS-422/485 Circuitry The RS-422/485 side of the Converter is made up of the driver, receiver, and line- termination networks. As described in Chapter 3 , you can use switch S2 to either connect the receiver’s termination network to the line (terminate the RS-422/485 port) or leave it unconnected (unterminated).
14 RS-232 ↔ RS-422/485 CONVER TER (DA T A ONL Y) 6. T roubleshooting 6.1 Calling Black Box If you determine that your RS-232 ↔ RS-422/485 Converter (Data Only) is malfunctioning, do not attempt to alter or repair the unit . It has no user-serviceable components.
15 APPENDIX: Pinouts Appendix: Pinouts T able A-1. Pinning of the RS-232 connector (DB25 female). Pin Number and Signal Function Pin1 — Frame Ground Connects the Converter’s frame ground to the frame ground of the RS-232 device.
16 RS-232 ↔ RS-422/485 CONVER TER (DA T A ONL Y) T able A-2. Pinning of the RS-422/485 connector (4-position ter minal block). Pin/Signal Function TXA and TXB Data received by the Converter from the RS-232 port is transmitted out of the unit over twisted-pair wires using these two outputs.
