CODE OPERATED SWITCH II 1.
CHAPTER 2: Introduction 2. 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. Configuration is port-independent: You may set different speeds, word sizes, parities, and flow-control requirements for each port.
CODE OPERATED SWITCH II 3. Installation 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. 3.1. 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.
CHAPTER 3: Installation 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.
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 SWA SWB SWC SWD SWE SWH SWI SWJ SWK Port Master Device Port 0 1 2 3 OFF ON OFF ON OFF OFF Set Switch 6 OFF ON 3.5.4 FLOW CONTROL (SWITCH 7) Flow Control Hardware (DTR/CTS) Software (X-ON/X-OFF) Set Switch 7 ON OFF 3.
CHAPTER 3: Installation Automatic Timeout Master Slave Leads Passed The COS II times the intervals between the reception of each character and the next. You may instruct it to return to an unlinked state after intervals of 2.5, 5, or 10 minutes, or you may disable this automatic timeout feature. SWF 5 and SWF 6 control this feature.
CODE OPERATED SWITCH II 3.6.2 SETTING THE ARMING CHARACTER WITH SWG 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. For a more detailed explanation of control codes, see Section 4.2. A note on abbreviations: LSB stands for least significant bit, MSB for most significant bit.

CODE OPERATED SWITCH II To Set SWB 8 Pass breaks Ignore breaks ON OFF 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. The following table shows the behavior of the COS II for different combinations of devices.
CHAPTER 3: Installation 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. To prepare the COS-II: 1. Make sure that SWA 8 is set to OFF, that is, to normal operation. 3. Slide the cover back onto the base of the COS-II, and secure it with the screws. 4.
CODE OPERATED SWITCH II 4. Operation 4.1. Introduction 4.3 Signaling a Lock 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.
CHAPTER 4: Operation 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. When the master port is switched to one of the slaves, the corresponding LED will glow continuously. 4.7.
