V.35 AND RS-530 MODEM ELIMINATORS 2. Introduction You can use your V.35 or RS-530 Modem Eliminator to connect one DTE (host, PC, or terminal) directly to another without needing to use modems or line drivers, as shown in Figure 2-1 below. You’ll just run cables from each of the DTEs and attach them to the Modem Eliminators’ data ports. Figure 2-1. Typical application. The units have a full-featured front panel, shown in Figure 2-2 below. The DB25 “MONITOR” port is for connection to a data-line monitor.
CHAPTER 3: Configuration and Installation 3. Configuration and Installation 3.1 Switch Setting Place the V.35 or RS-530 Modem Eliminator between the DTE devices you want to connect, in a cool, dry place close to an AC outlet. Once you’ve done so, scan Section 3.1.1 below and on the next page for the default settings of the unit’s DIP-switch positions.
V.35 AND RS-530 MODEM ELIMINATORS Once you’ve finished setting positions 7 and 8, set the other positions of switch SW5 as necessary. Positions 1 and 2 determine how the Modem Eliminator handles the CTS signal: • Position 1 ON: On data port J1, CTS is permanently ON (held high). • Position 1 OFF (default setting): On data port J1, CTS follows RTS after a delay (user-selectable through the front-panel DELAY switch; see the next section) elapses.
CHAPTER 3: Configuration and Installation 3.1.3 THE FRONT-PANEL BAUD THUMBWHEELS If the Modem Eliminator is set for synchronous operation with internal clocking (DIP switch SW5 positions 7 and 8 both OFF—see Section 3.1.1), turn the unit’s two front-panel BAUD thumbwheels to the setting corresponding to your desired data rate. Refer to Table 3-2 below; to get any setting listed in the “BAUD-Switch Position” column, turn the left-hand wheel to the “tens” value and the right-hand wheel to the “ones” value.
V.35 AND RS-530 MODEM ELIMINATORS 3.2 Cabling After you’ve finished setting the V.35 or RS-530 Modem Eliminator’s controls, run cables from the two DTEs to the J1 and J2 connectors on the unit’s rear panel. The length of these data cables should not exceed the maximum recommended in the RS-530 and V.35 specifications: 4000 feet (1219.2 meters) with 24-AWG twisted-pair wire at data rates up to 100 Kbps.
CHAPTER 4: Operation 4. Operation 4.1 The LEDs While your V.35 or RS-530 Modem Eliminator is operating, you can watch its five front-panel LEDs to monitor the data and contol signals sent from, and received by, data port J1. The five LEDs indicate the states of these signals: LED SD RD RTS CTS DCD V.35 Signal SD A RD A RTS CTS DCD (RLSD) RS-530 Signal TD A RD A RTS A CTS A DCD (RLSD) A 4.
V.35 AND RS-530 MODEM ELIMINATORS 4.3 The Loopback Switch The front panel also contains a slide switch marked “LB” (“loopback”). If ever your data doesn’t seem to be getting across the Modem Eliminator link properly, you can temporarily move this switch to the left-hand (ON) position to have the unit loop the data signals from the devices attached to data ports J1 and J2 back to those devices.
CHAPTER 5: Troubleshooting 5. Troubleshooting 5.1 Contacting Black Box If you determine that your V.35 or RS-530 Modem Eliminator is malfunctioning, do not attempt to alter or repair the unit. It contains no user-serviceable parts. Contact Black Box Technical Support at 724-746-5500. Before you do, make a record of the history of the problem. We will be able to provide more efficient and accurate assistance if you have a complete description, including: • the nature and duration of the problem.
V.35 AND RS-530 MODEM ELIMINATORS Appendix: Connector Pinouts The table below and on the next page shows the pin assignments for the Modem Eliminator’s interfaces and connectors: The data ports of the ME110A models are M/34 female connectors pinned for V.35; the monitor port is a DB25 female connector pinned for V.35. The data ports and monitor port of the ME111A models are DB25 female connectors pinned for V.35.
