Accent PC The Accent PC is an internal synthesizer that uses a device driver to communicate with JAWS. The Accent PC should be installed in your PC, a speaker or headphones should be connected to the output jack of the synthesizer, and the volume knob should be turn to a middle range position. When you turn on the PC, it should say "Accent Ready". The device driver that is use with this synthesizer is a file named "SPKACNT.DVC". This file is located on the Accent disk that came with your synthesizer. The software driver file must be copied into the JAWS subdirectory of your boot disk. Then you must add the following line of information to the CONFIG.SYS file. device=\JAWS\spkacnt.dvc If the software driver is copied to the proper location, then the synthesizer should say "Accent Ready" twice when you turn on your PC. Its first announcement should be heard as soon as power is turned on. The second announcement is heard when the software driver is loaded. The Accent Mini and Toshiba models only say "accent ready" once. If you do not hear the proper ready message, then you have a problem that must be addressed before JAWS can speak. JAWS and internal Accent synthesizers will communicate through LPT3 as the default. If you want to use another parallel port, see below. Changing Ports with Internal Accents The "SETACNT" program on the Accent disk is used to tell the device driver to use a different port. Instructions for using this Accent utility program are in the Accent manual. If you change the device driver to a port different from the one selected when you installed JAWS, then you must also tell JAWS to use the new port. This is done by changing the information in the batch file that is usually used to load JAWS(JAWS.BAT). You can used LPT1 through LPT8 for internal Accent synthesizers. If you were to change your LPT number from "3" to "4", then you would change the LPT number shown below to "4". J_ACNTPC LPT4 Network Systems If you are trying to use an internal synthesizer on a network you may encounter a hardware conflict. Many networks claim LPT3 and sometimes other printer ports for use with network printers. In this situation, the networks capture all information going out the LPT port and send it to the network printer. This hardware conflict must be resolved before the Accent and JAWS can talk. The solution is to either re-configure the network (your work station) so it will not use LPT3, or you can setup JAWS and Accent to use another printer port, as discussed above. HARDWARE CONFLICTS Even though the Accent PC is a very compatible board and is usually very easy for a PC to work with, occasionally a conflict will develop. The most common problem is a base address conflict. Sometimes the hard disk controller will be configured to use the same base address or I/O address as the Accent. When this occurs you will observe the following behavior sequence. 1. When the computer is turned on it will say "Accent Ready" as it should. 2. When the Accent driver file is loaded it will say "Accent Ready" as it should. 3. The computer will act and perform normally, you can even run the Accent demo program and it will perform properly. 4. However, when you load JAWS, it will not announce its active status or say the user's name and registration number, as it should, and the system will be locked up. The Accent may speak a few characters now and then, but it will be obvious that something is wrong. If you experience the above behavior, then you need to change the base address of the Accent. The I/O Address, or Base Address, is controlled by Switch #2, which is about 1.5 inches from the bottom of the board, directly above the left edge of the edge connector. "On" is up, "off" is down, therefore up =0, down =1. Switches are numbered 1 through 8 from left to right. When changing these switch settings, we recommend that you hold the board upside-down, so that up = "on" or "1", and the most significant digit is on the left (8-1 from left to right). These switches represent bits in a binary number, but you have to add two zeroes on the right side (least significant) in order to convert correctly to binary or hexadecimal. Take switches 8, 7, 6, 5, 4, 3, 2, 1; add two zeroes; then convert to hex, based on this binary number. Default is 1010101000 binary, equals 2A8 hex. Do not forget that the two zeroes on the right are always zero and that there are no physical switches to represent that position. You should not use the address 2DX, for this is the address of the hard disk controller (x represents 1 digit). Do not use 2Fx, 32x, 33x, 37x, 38x. 100 through 1ff hex is reserved for output use only, and these addresses should not be used. 39x is the highest available address. 300 hex is used by the Prose 4000. To set this address for the Accent PC, first convert to binary: 300 hex = 1100000000. To convert to the proper switch pattern drop off the 2 zero's on the right, remember to turn the card upside-down, then first digit on left matches first switch on left, and up = 1, down = 0. The first two switches on left should be up, the rest down. After changing the switches on the synthesizer board you must use "SETACNT" to change the device driver: Type "SETACNT SPKACNT.DVC" and press ENTER. If it cannot find the device driver, then check to be sure you are using the correct disk or subdirectory, or that you have a path defined. Select "2" from the menu, and enter the address in hex, e.g "300" or "2A8". This address value must match what the board is set to. then press 5 and Y to exit the program. The following chart shows the conversion between binary and hexadecimal numbers. It shows the hex address on the left and the position of each switch. "o" means "on", "f" means "off". Since the numbers of the switches shown on the chart run from 1 through 8 the synthesizer should not be turned upside down when setting the switches from this chart.
