The BayTech Model 24SII Data Exchang e Sy stem (DES) is a hig h performance peripheral sharing solution offering v ersati le and flexi ble connectiv ity between computer s and var ious peri pheral dev ices.
Each port offers high speed data communicati on wi th unidir ectional serial thr oughput up to 460k bi ts per second (bps) and parallel speeds exceedi ng 60k character s per second ( cps). The Model 24SII controller board is used pr imaril y as a data communi cations bus w ith throughput capability up to 5.
The Model 24SII's g enerous buil t-in buffer also sav es valuabl e computer time by spooling data until the pr inter or plotter can r eceiv e it, keeping your users and computers w orking full time instead of wai ting . The spooli ng buffer on the Model 24SII D ES can rang e from 0 MB to 16MB in 1M B or 4MB i ncrements.

The information contained in this section is pr ovi ded as an over vi ew and guide to config uration and set-up of the Model 24SII DES. The appropriate secti ons of the manual should be referred to for more in- depth information pertaining to a specific function or for alter nativ e methods.
To run INSTALL, use the follow ing procedur e: 1. Insert the so ftware utility diskette in to drive A (or drive B) and from the prompt ty pe INSTA LL followed by ENTER . 2. A menu titled "Drive & Directory Definitions" will appear on y our screen.
The standard Model 24SII D ES req uires 115 VAC, 50/60 H z. pow er and comes wi th a three-pr ong pow er cor d. Do not attempt to operate the unit w ith a tw o-prong socket or adaptor . 230 VAC, 50/60 Hz . is optional. The Model 24SII DES pow ers-up when y ou press the pow er switch, located on the front of the unit, to "ON".
Connect the proper ser ial cabl e between C OMx (w here x = 1, 2, 3, or 4) of a PC, or dumb ter minal, to Port 1 of Module 1 (the master configuration por t).
Serial ports pow er-up from the factory at: 9600 baud rate 8 bit w ord size 1 stop bit no parity XON/X OFF disabled Printer shar ing mode: Bi directi onal.
If using an IBM PC or compatible to configur e the Model 24SII D ES, first make a copy of the BayTech supplied support softw are disk and store the orig inal in a safe place. (Refer to y our DOS manual for copy instructions). You w ill be using the TERM program created by running the INSTALL prog ram ( see Section 4.
3. Refer to the upper r ight hand cor ner of the screen for Handshaking line status. RTS, CTS, DSR , and DTR should all be HIGH. The DCD line is not looked at by the terminal emulati on prog ram therefore its status can be ignor ed. If these signals ar e not high at thi s point, check to ensure the corr ect cable is connected.

If you are connecting a dev ice other than another BayTech product, you must r efer to the operator's manual for y our eq uipment to determine w hich pins are defined as TX+ , TX -, RX +, and RX -.
W hen connecting an EIA- 422 dev ice to a computer por t on the M24SII-V07 I/O module using 4-w ire Oper ation and unidirectional Printer Shar ing M ode, the cable req uired to connect the tw o devices must have R X+ w ired to TX +, and R X- w ired to TX -, HSO+ w ired to HSI+, and HSO- w ired to H SI-.
PRINTER PORTS NOTE: Printer ports using this configuration will support hardw are handshaking onl y. Y ou must ensure har dwar e handshaking i s supported by the eq uipment that will connect to these ports.
NOTE: If your EIA-422 dev ice has onl y one output har dw are handshake line (i .e., no HSO+ and H SO-), connect thi s sing le handshake line to HSI- on the M24SII-V07 modul e (Pin 5) .

The Model 24SII DES will translate for serial devices using different configurati ons. This al low s y ou to mix -and- match dev ices hav ing different configurations.
& The Model 24SII DES has four For m Feed Modes allow ing y ou to determine w hen form feed occurs at the printers you ar e selecting : at the beginni ng of printing , at the end of printing , or both. This feature is useful w hen sending D OS files to a laser pr inter.
The Model 24SII Data Ex change System allow s peripheral (pr inter, plotter) shar ing , specific peripher al selecti on or peripher al contention, and buff e ring of print data.
In multiple pr inter appli cations, the M odel 24SII DES g iv es you the capability of sending print jobs to the first available printer (contention mode).
The Model 24SII DES pow ers-up from the factory in contention mode. .
The port select seq uence may be sent as a separ ate ASCII file preceding the print job, v ia DOS batch files, as part of a printer initialization strin g, or by using the u tility software.
In Port Select Mode B (printer sel ection at begi nning of pri nting) , a print j ob is ended only when no characters are recei v ed by the M odel 24SII DES from the computer for the specified Input Inactiv ity Timeout period onl y. CA UTION: The Input Inactivi ty Ti meout should not be set to 0 (z ero) seconds (disabl ed) in Port Sel ect Mode B.
If a computer wishes to cl ear the buffer, the computer sends the Port Select Code follow ed by CLR and a terminating character (Enter/Retur n or Line Feed) to the Model 24SII D ES. This comm and will only affect print jobs originated by that particular computer.
The Model 24SII Data Ex change System allow s pairs of computers (or computers and other dev ices such as modems, scales, data collection eq uipment, etc.
Do not send both Enter/Retur n and Line Feed as the terminati ng character. The M odel 24SII DES looks for either Enter/Retur n or Line Feed as the terminating character, but not both.
NOTE: Using R AMEX EC to select another computer port is not sugg ested. This is because R AMEX EC does not prov ide full duplex communication so y ou cannot see the On Line or Busy message if you attempt to use R AMEX EC to deter mine w hether or not you g ot connection to the other computer por t.
For ex ample, suppose y ou want to communi cate w ith a 2400 baud modem connected to Port 2 of Module 2 and y our PC i s connected to a computer port set at the M odel 24SII's factory default seri al configuration ( 9600 baud, 8 data bit, 1 stop bit, no par ity , and XON/X OFF disabl ed).
BETWEEN COMPUTER A ND PERIPHERA L THROUGH MODEL 24SII W hen a.
BETWEEN COMPUTER A ND COMPUTER THROUGH MODEL 24SII W hen Computer A tr ansmits data to C omputer B throug h the Model 24SII DES, the data is r eceiv ed from Computer A and stored i n a 512-character buff er which in tur n retransmi ts it to Computer B.
BETWEEN COMPUTER A ND PERIPHERA L THROUGH MODEL 24SII W hen a computer tr ansmits data to a peri pheral dev ic e throug h a computer port on the M odel 24SII DES, the data is receiv ed and stored in the spooli ng buffer (standard 1M B; optional up to 16MB) whi ch in turn r etransmits it to a per ipheral devi ce throug h a printer port.
W hen the buffer of the Model 24SII D ES can receiv e more data, the Model 24SII DES will send an X ON to Computer A. NOTE: For computers sending binary data and using XON/X OFF handshaking, the i nput flow contr ol (Recv ) should be enabled and the output flow control (Xmit) should be disabled.
This command should be enter ed in all capitals w ith only one space between EC HO and the $. Please r efer to you DOS manual for instructions on creati ng DOS batch files. Progr ams such as W ord Perfect and W o rdStar typical ly send a printer initial iz ation string before any data.
