  • Page 5: Introduction

    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.

  • Page 6: Installation

    CODE OPERATED SWITCH II 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.

  • Page 7: Functions And Arrangements Of The Switch Banks

    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.

    CODE OPERATED SWITCH II In addition, there are some system characteristics that are set with the eighth DIP switch of the individual port switch banks. Sections 3.6 and 3.7 explain these functions in depth. 3.4 Bank Assignments The individual port switch banks are assigned as follows: Bank Label Port...

    CODE OPERATED SWITCH II 3.6.2 S ETTING THE RMING HARACTER WITH Switch Bank SWG supplies a portion of the control-code sequence, the sequence that activates the Switch. The arming character, the ASCII code that alerts the COS-II to an upcoming switch action, is set with SWG. The settings are given in the chart below.

    CODE OPERATED SWITCH II Set SWB 8 Pass breaks Ignore breaks Lead Pass-Through This function allows the COS II either to pass hardware-handshake leads to connected devices, or to block them. If they are blocked, the leads will still be used to regulate the 8K internal buffer of the Switch.

  • Page 17: Connecting And Powering-Up The Cos-Ii

    3.9. Connecting and Powering Up the COS-II Once you have configured the internal switches and jumpers, you can connect your devices and the wallmounted power jack to the COS-II. Before you begin, you might wish to check the settings of all the DIP switches again, to make sure you have set them correctly.

  • Page 18: Operation

    CODE OPERATED SWITCH II 4.1. Introduction The primary action of the Switch consists of detecting and responding to control-code sequences. As it switches to a particular port, the COS-II establishes a link between the master and the slave device. After the COS-II has switched, it can lock the link out, that is, it can ignore all requests by other ports until the link is broken.

  • Page 19: Indicators

    4.6. Indicators The front panel of the Switch contains 10 LEDs. The Power LED, at the extreme right, will glow steadily when power is on. The Lockout LED, a green LED at the extreme left, will light when the unit is in lockout. Each of the eight port LEDs, numbered 0 through 7, will respond to the action of the COS II.
