CHAPTER 1: Specifications 1.
S↔P (SERIAL↔PARALLEL) CONVERTER (128K) 2.0 Introduction The S↔P (Serial↔Parallel) Converter (128K) is a serial-to-parallel or parallel-to-serial converter (conversion direction is user-selectable). It operates at speeds ranging from 600 bps all the way up to 76.8 Kbps and has 128K of buffer memory, which is ideal for most ordinary print jobs and other types of file transfers.
CHAPTER 3: Installation 3.0 Installation 3.1 What You’ll Need Before you attach any cables or turn anything on, make sure you have everything necessary to set up your S↔P Converter (128K) system. Each S↔P Converter comes with its own power supply and a 6-foot (1.8-m) flat satin cable with RJ-45 male connectors. This cable can connect the Converter to an RJ-45 serial port—or to a modular adapter attached to a different type of serial port—on a nearby device.

S↔P (SERIAL↔PARALLEL) CONVERTER (128K) EDN25C. Two DB25-female-to-RJ-45-female adapters pinned as in Figure 3-1 should be connected to the EDDC, one at each end. Our product code for these adapters is FA081-R2. Cable running from the Converters’ serial ports to these modular adapters could be the two flat satin cables that came with your units.
CHAPTER 3: Installation • If you’re running EDDC, attach the EDDC to the Converter-end adapter and run it to your serial device. Attach its free end to the DB25 female serial port on the device or to the DB25 female connector on a second adapter. Attach any additional cable or adapters needed at the device end. 4. Now you’re ready to set the switches on your S↔P Converter (128K). First set its external DTE/DCE slide switch.
S↔P (SERIAL↔PARALLEL) CONVERTER (128K) Table 3-1.
CHAPTER 3: Installation 3.2.2 CONVERTER-PAIR PROCEDURES 1. First locate each Converter within 20 feet (6.1 m) of its associated parallel device, close to a power outlet. 2. Run your parallel input cable from the PC (or whatever device is transmitting) to the input-side Converter’s parallel (DB25 female) port. 3.
S↔P (SERIAL↔PARALLEL) CONVERTER (128K) Set DIP switch position 8 to ON (parallel to serial conversion) on the S↔P Converter connected to the input (transmitting) device and to OFF (serial to parallel conversion) on the Converter connected to the output (receiving) device. Set switch position 6 to ON for self-test mode on the output-side Converter and to OFF for normal operation on the input-side unit (setting both to ON at the same time might yield misleading self-test results). 6. Test your setup.
CHAPTER 4: Operation 4.0 Operation Once you’ve installed the S↔P Converter (128K), run a few test transmissions. If one or more don’t get through intact, see Chapter 5: Troubleshooting. If at any time something goes wrong with a transmission, you can press the Reset button to reset the Converter without having to unplug it or restart your devices. Also see Chapter 5 for troubleshooting suggestions. After the Converter is up and working properly, few adjustments should be necessary.
S↔P (SERIAL↔PARALLEL) CONVERTER (128K) 5.0 Troubleshooting 5.1 Common Concerns This section lists some problems that might come up during installation or operation of the S↔P Converter (128K), along with some solutions. 5.1.1 THE CONVERTER’S POWER LED DOESN’T LIGHT UP 1. Make sure the Converter’s power supply is firmly mounted in the outlet. If it is, go to Step 2. 2. Try a different outlet, or test the outlet you have been attempting to use by plugging another device into it.
CHAPTER 5: Troubleshooting 4. Check the Converter’s DTE/DCE slide switch and the wordstructure and flow-control settings of its DIP switch. If they are correctly set for communication with your serial device, go to Step 5. 5. A cable run may be too long. Cable length for parallel communication must not exceed 20 feet (6.1 m) between any pair of devices; serial cable length must not exceed 50 feet (15.2 m) for UTP or 500 feet (152.4 m) for extended distance data cable.
S↔P (SERIAL↔PARALLEL) CONVERTER (128K) or parallel cable, or an identical cable you know is OK. If communication goes smoothly for both of your devices and their associated cables when the Converter isn’t involved, go to Step 10. If there is still a problem after you make these substitutions, any of several device-related difficulties may be occurring. Some examples: • One of the attached devices might be set up to communicate through the wrong port. • One of the device ports is broken.
CHAPTER 5: Troubleshooting 5. A cable run may be too long. Cable length for parallel communication must not exceed 20 feet (6.1 m) between any pair of devices; serial cable length must not exceed 50 feet (15.2 m) for UTP or 500 feet (152.4 m) for extended distance data cable. If either of your devices is too far from the S↔P Converter it’s directly attached to, move the Converter or move the device. If your Converters are too far from each other, move one of them and, if necessary, its attached device. 6.
S↔P (SERIAL↔PARALLEL) CONVERTER (128K) 11. If the problem isn’t solved, check the hardware and software configurations of the attached devices. If possible, test both of your devices by detaching them from the S↔P Converter and connecting them to each other with your input or output cable. Attempt communication through the same parallel ports you were using when the problem occurred.
CHAPTER 5: Troubleshooting 5.2 Calling Us If your Serial↔Parallel Converter (128K) seems to be malfunctioning, do not attempt to alter or repair the unit. Contact us; the problem might be solvable over the phone. Before you do, make a record of the history of the problem.
