1. Specifications

CODE OPERATED SWITCH II

The Code Operated Switch II (COS II) makes code-operated switching possible for diverse combinations of serial devices. As it switches, the COS II also reconciles differences in word size, speed, flow control, and parity for up to four devices. An Expansion Board, available separately, doubles the maximum number of devices, to eight.

Configuration is port-independent: You may set different speeds, word sizes, parities, and flow-control requirements for each port. The 8K buffer handles speed conversions from 110 bps to 19,200 bps. DTE and DCE are also independently determined for every port.

A control sequence manages the switching for the COS II. The COS II will accept the sequence from any port—the master port, which will ordinarily have a PC or terminal connected to it, or any of the four (or eight) slave ports.

A special graphics timeout lets you send graphics files through the Switch without the chance of accidental switching. In graphics mode, the COS II recognizes the appearance of the control code only when the code characters are preceded by a pause of a specified length. The COS II treats all other occurrences of the control code as data—they are passed along to the slave device with the rest of the characters in the file.

Any office, lab, or shop with a variety of serial devices will benefit from a COS II. Use it in a typical multiprinter office, or to transfer files between computers. You could also set up the COS II as the link between a single PC and a mixture of highand low-speed remote data lines. The COS II will pass your high-speed—9600-bps—data without interference, while the internal buffer of the COS will downshift PC data for the slower modems.

2. Introduction

CHAPTER 2: Introduction

3.1. Introduction

In addition to this manual, your Switch package should contain one standard switch unit and a wallmounted power supply. After you’ve unpacked the Switch, take a few minutes to look through this manual. You will need a screwdriver large enough to remove the case screws, and a small screwdriver or other edged tool for setting DIP switches. Also, you might want to refer to the manuals of the devices you plan to connect to the COS-II.

Installing the COS-II is a simple, three-step task that should take no more than an hour to complete. First, you’ll configure all of the DIP

switches for the internal options of the COS II. Then, you’ll specify DTE or DCE for each port by setting shunt jumpers. Finally, you’ll cable the Switch to your devices and connect power to the COS II.

3.2. Setting the DIP switches

In order to set the DIP switches, you’ll need to open the case of the COS-II. There are several screws on each side. Remove them, and lift the case lid from the body of the COS-II. The board layout of your unit should match the diagram shown below (Fig.1).

CODE OPERATED SWITCH II

The board layout for the Four-Port Expansion Board is shown on this page (Fig. 2). If you have ordered one, check your Board to make sure it matches.

NOTE: Every time you change the DIP switch

settings, you must press the reset button located on the front panel of the switch, or unplug the power supply. The COS-II will not process any data during a reset.

A note on charts: you’ll find all the charts printed in this chapter duplicated either in the Appendix or in the Quick Reference Guide.

3.3 Functions and Arrangement of the Switch Banks

On the standard board there are seven banks of DIP switches, of which five control the characteristics of the individual ports (SWA through SWE). The remaining two banks (SWF, SWG) control options that affect the entire system. The Four-Port Expansion Board adds individual port banks SWH through SWK.

A note on terminology: This manual will use the following system to designate individual switches within each switch bank. The bank label will be given first, followed by a hyphen and then the number of the DIP switch. “SWA-6” refers to the sixth DIP switch of Switch Bank A. Also, the words “ON” and “OFF” are used in the switch charts, but your banks may have the words “CLOSED” and “OPEN” printed instead. “CLOSED” is equivalent to “ON,” and “OPEN” is equivalent to “OFF.”

You’ll set the following options with Switch Banks SWA through SWE (the individual port banks):

• Data rates, from 110 to 19,200 bps

• Parity—even, odd, or no parity

• Word sizes —7 or 8 bits

• Flow control by hardware (DTR/CTS) or

software (X-ON/X-OFF). Section 3.4 covers these banks in more detail.

The two banks SWF and SWG (system banks) regulate:

• Responsibility for the Link Command (from

master or slave port)

• Automatic timeout period

• Length of pause in Graphics Mode

• Lead Pass-Through

• Arming character
