RS 2. 32 Connections That WORK Connecting Devices or Converters. Connecting two devices using RS 2. RS 2. 32 device working by helping correct the RS 2. This FAQ will help you troubleshoot and correct such problems. Usually inputs are connected to inputs and outputs to outputs. People dont realize that there are two types of RS 2. DTE and DCE type, and that the signal names and pin numbers are the same, but signal flow is opposite The pin labeled Tx can be input, and Rx the output. The two ports types are complementary, the Output signals on a DTE port are Inputs to a DCE port, and Output signals on a DCE port are Inputs to a DTE port. The signal names match each other and connect pin for pin. Signal flow is in the direction of the arrows. How Can I Identify DTE or DCE Type Connections What devices have DTE type RS 2. A DTE device is Data Terminal Equipment, this includes Computers, Serial Printers, PLCs, Video Cameras, Video Recorders, Video Editors, and most devices which are not used to extend communications. Think COMPUTER for DTE. What devices have DCE type RS 2. A DCE device is Data Communications Equipment, this includes devices intended to plug directly into a DTE port, PDA cables, Modems and devices that extend communications like a modem, such as RS 4. RS 4. 85, or Fiber Optic converters or Radio Modems. Think MODEM for DCE. Rule of Thumb When connecting a DTE device to a DCE device, match the signal names. When connecting two DTE or two DCE devices together, use a Crossover cable. TD crosses to RD, RTS to CTS, DTR to DSR as shown in Modem to Modem connections. PMMNM The cable for two computers DTE also simulates modem connections to CDDSR, so it is commonly called a Null Modem cable. Are My Devices Wired As DTE or DCE How to Check. Use Rule of Thumb If the device plugs into the computer serial port and works normally, the device is wired as DCE or the connection cable is a crossover type that makes it work as a DCE. If the device connects to the computer port using a null modem crossover cable, it is wired as DTE. Use RS 2. 32 Line Tester A quick and easy way to determine the DTEDCE port type is to use a RS 2. PMTT. The tester can show the signal state of any active RS 2. LEDs lighting Red or Green. Active data lines are output from a device, they may be either High or Low. Just plug the tester into either of the two devices, see which lines are lit, unplug it, then plug it in to the other device, see which lines are lit. If the same light TD or RD is lit, use a crossover cable or null modem connector that swaps the connections for pins 2 and 3 and other pins as needed. If the device is port powered check the active side, then plug in the port powered device and see if other TD or RD LED is lit. If not, try swapping the leads with a null modem cable, see if the other LED now lights. If not, you may not have enough voltage on the handshaking lines of the port to steal power from. Use a DC Voltmeter Technicians with a DC voltmeter can use it to measure the DC level from signal ground pin5 on DB9, pin7 on DB2. When the unit is powered and not sending data, the output line will have a DC voltage of minus polarity, 3 volts to 1. The other pin will have little or no voltage. For example, we measure 1. DB9 connector and the line is labeled RD or Rx, then the device is wired as DCE. If we measure the voltage on pin3, it is DTE. Measure pin 2 and pin 3 to ground pin 5 DB9 pin 7 DB2. If the cable and device have voltage on the same pin, you need to use a crossover or null modem connector that swaps pins 2 3 and the other pins. Electrically active handshaking lines will be negative when not asserted or positive when asserted. Active handshaking lines can be found by measuring each pin for voltage. Output lines will have voltage. On a DTE, DTR and RTS will have voltage if used. On a DCE, DSR and CTS will have voltage, and if a modem with CD Carrier Detect and RI Ring Indicator these last two will be low until Ring is detected or a Carrier connection is made. If handshaking lines dont have voltage when the device is powered on and ready, the device doesnt output them, they may be looped back, RTS to CTS and DTR to DSR. You can turn off the device power and measure for continuity zero ohms between pins to confirm if they are looped back. Other RS 2. 32 Connection Problems. Handshaking lines RTS and CTS not interconnected, DTR and DSR not interconnected. Swap as needed. Programs may use the RTSCTS connection to check that a device is ready to receive data and respond. If there is No CTS connection, the program will never send data, but wait a long time or timeout with an error. The RTS line may need to be looped back to the CTS input. Data errors can occur if the device actually requires handshaking. Programs may also use the DTRDSR line connection to check that a cable is connected or that the device is turned on. If there is No DSR signal, the DTR line may need to be looped back to the DSR input. Some devices use DTR handshaking. Each signal required for unit operation must be carried through by the isolator, modem or RS 4. The primary 2 Channels for RS 2. Receive Transmit. There are 2 data flow control channels, RTS and CTS. If these are missing, data is lost, characters missing, or files scrambled. Connections to Telephone ModemFAX modem Make sure CD RI lines are connected.
