9760 HS COMMUNICATIONS PARAMETERS CC1 to HS Interface: (Comm Parameters) Equipment # Baud Rate Parity 16 9600 EVEN IMPORTANT NOTE: Users upgrading from previous hot switch models should consult Appendix 4.2 HS Update (Previous Model of Hot Switch Installed), where important differences between previous and current models are highlighted.
1.2 CC1 CONNECTION GROUPS The rear view of a matrix switch (referenced in the block diagram of Figure 1-1) is shown in Figure 1-2. Outputs destined for HS connections can be categorized, corresponding to the designated functions of the subunits to which they are attached on the hot switch. For discussion purposes, these outputs are partitioned into three groups: the Control group, the Diagnostic-Peripheral group and the External Expansion group.
1.3 HS HARDWARE THUMBNAIL Figure 1-3 expands the HS portion of Figure 1-1 to illustrate an uncluttered, thumbnail rear view of the hot switch subunits that comprise a default HS configuration. Connection cable destinations from each CC1 (matrix switch), referenced in the previous figure, are attached to the appropriate side (CC1 ‘A’ or CC1 ‘B’) of the hot switch subunits.
THE CCC (Computer Changeover Control) 120-240 VAC IN CA C 50/60 Hz A OUT 1 B B LOGGING PRNTR 20053 NOTE: When upgrading to the current hot switch from a previous model, note the following. The data cable, previously used to connect RJ-45 port 5 on each switch and the corresponding COM 1 [S1] and COM 2 [S2] ports on the hot switch, cannot be substituted here. The CCC subunit is the heart of the hot switch. Data connections between the interfaced CC1s (matrix switches) and the HS are located here.
In addition to communications, there are number of additional functions handled by the CM9760-CCC. POWER The power-input connector, fuse, and ON/OFF switch are located here. Input power for the entire HS originates here. Power is distributed to the CPS and SEU subunits via DB37 common bus connections. LOGGING PRINTER PORT This is used, if desired, as an output logging device for system or status reports related to hot switch operation only.
This allows users with existing RS-232 DT devices to retain that configuration capability in the new HS. Figure 1-6 highlights the geometry of this hookup. Additional DTs of the same type must be connected to CC1 Sercom ports (via SEU output ports of the HS) and require RS-232 to -422 converters. 20078 Figure 1-6. COM 2 Port Options A couple of working rules with respect to diagnostic tool availability are in order here.
THE SEU (Serial Expansion Unit) 1 CC1 A 8 1 CC1 B 8 1 EQUIPMENT 8 IN OUT 9 16 20085 The SEU subunit of the HS, like that of the CPS, is also divided into three sections. Devices connected to the SEU EQUIPMENT output ports are under the control of only one CC1 at a time. The controlling switch is designated the Master, regardless of mode (synchronous or asynchronous).
A NOTE OF CAUTION: Random attachment of cabling between CC1s and SEUs can lead to confusion about what is attached where. It is suggested that you map the physical port arrangement found in your CC1 outputs to those utilized on the SEU (as far as that is possible). One method is to mentally rotate the SEU (clockwise or counterclockwise, it does not matter) and associate the port locations you use on the SEU to those existing on the CC1.
1.5 INSTALLATION PREVIEW Figure 1-11 combines elements of previous illustrations into what is essentially a wire routing of the block diagram of Figure 1-1. This is an overview of the physical geometry of an HS integrated into a basic, default system configuration. Section 2.1 Physical in Section 2.0 Installation, breaks up Figure 1-11 into its logical component groupings, where cabling requirements for each section are isolated and examined in detail.

SECTION 2.0: INSTALLATION 2.1 PHYSICAL As previously stated, the connections from 9700-CC1s (CC1-A and -B) to the HS are duplicates of each other. Except where noted, all the plugs and connectors found on the rear of the CC1 have corresponding port representations on the subunits of the HS. 9700-CC1 TO CCC (Control Group) CC1 A MODEL SERIAL VOLTS WATTS FREQ AMPS • RJ-45 (A & B) DATA LINE INPUT PORTS ARE RS-422; THE DB9, (A & B) PORTS ARE RS-232.
9700-CC1 TO CPS (Diagnostic Group) The connection points for diagnostic and monitor tools for hot switch and system status are shown in Figure 2-2. Note that COM 1 on either CC1 (the normal connection point for the PC w/MGR in a stand-alone CC1 configuration) is run to the appropriate COM 1 input connector on the CPS. COM 1 output on the CPS is reserved for the PC w/MGR connection. If a CC1 COM port on the switch is defective, the other port can be used, but you must still connect to COM 1 on the CPS.
9700-CC1 TO SEU (Expansion Group) Devices connected to the EQUIPMENT output port (which the designated Master switch has access to) are implemented here. Port destinations for cable connection inputs from the matrix switches are not predefined. This was discussed in the SEU portion of 1.4 Subunit Highlights in Section 1.0 Introduction. It is recommended that the SEU connection template (located at the back of the manual) be utilized here.
DIP SWITCH SETTINGS Some HS operating parameters are determined via two DIP switches, which are physically located to the left of the front panel LED displays, but behind the front panel of the CCC itself. Figure 2-4 illustrates all DIP switch settings. Factory default is indicated.
2.2 POWER-UP AND INITIALIZATION Once configuration files have been programmed and loaded and all connection cabling has been run, then the associated CC1s, the hot switch and all connected devices can be turned on. The order of equipment turn-on is immaterial; however, if the HS is turned on before either CC1 finishes initialization, the online LEDs (A and B) on the front panel of the CCC will alternate rapidly back and forth.
SECTION 3.0: OPERATION 3.1 PRELIMINARY REMARKS There are two modes of HS operation. One is termed the synchronous mode and the other, the asynchronous mode. Synchronous mode, of course, is the desired mode of operation. It is the optimal mode of operation and the one the HS is designed to operate under. It is also the default mode of operation and the only mode that provides proper backup to the system.
3.3 OPERATOR TOOLS LEDs A visual check of LED activity should be the top item on your checklist for determining the operational status of the HS and the attached system.
An operational system is always in synchronous or asynchronous mode; otherwise, the system is down. There are no intermediate operational states. Table A relates LED activity to the function listed in the left-hand column for the given operational modes. We use the following visual icons to represent (to the user) the visual state of the front panel LEDs. LED LEGEND: RELATIVE LED LOCATION AND IDENTIFICATION MIRRORS THAT USED ON THE CCC FRONT PANEL.
The following table illustrates how to implement these actions for the HS. Included are pertinent “before and after” visual changes associated with the action along with applicable notes about system operation. The shorthand, visual icons used in the LED “legend” and Table A of the preceding section are also applicable here. Table B.
3.4 OPERATOR RESPONSES AND METHODS User interaction with the HS is necessary when (1) a system error occurs, which generates a FAULT LED, and (2) when a software/hardware change or upgrade to the system must be made. System FAULTS are discussed first. SYSTEM FAULTS Although error response is addressed in the previous table, not all FAULT situations are covered there. Any alarm results in the FAULT LED being lit. An associated audible notification also occurs if optioned via DIP switch.
DIAGNOSTIC MONITOR AND SYSTEM WINDOW USE Normal Operation During normal startup, the diagnostic screen on the monitor (attached to the VGA output of the CPSsee Figure 1-11) reflects successful hot switch initialization. Likewise, the system window of the PC with MGR that is attached to the COM 1 output port of the CPS reflects the online status of the system node (see Figure 3-1 below), but gives no additional information.
Table D. Diagnostic Displays A-SIDE DIAGNOSTIC B-SIDE DIAGNOSTIC COMMENTS DIP 1-2 is ON. The diagnostic screens illustrated here are those seen prior to the implementation of each function listed, unless noted otherwise. Starting pointinitialization screens (normal start-up) 20087 20086 OPERATOR SELECTED ACTIONS FUNCTION A-SIDE DIAGNOSTIC B-SIDE DIAGNOSTIC Change Control COMMENTS Gone from A- to B-side control.

Table D. Diagnostic Displays (continued) INITIALIZATION ERROR DISPLAY FUNCTION A-SIDE DIAGNOSTIC B-SIDE DIAGNOSTIC COMMENTS Initialization failure. One side fails to boot up or establish communication with the HS 20092 20093 B-side fails. B-side diagnostic will initially show “Setup Complete” and then revert to a port error readout. It never comes online (A-OFF). The A-Side is online (A-MST), asynchronous mode. System box or error line initially shows “Setup Complete” and then shows port error.
SYSTEM UPDATE PROCEDURE Table E (see NOTE at end of Table) describes the procedure to follow when it is necessary to update, change, or add any hardware/software item associated with a hot-switched, online system node. The procedure, explicitly detailed in Table E, proceeds through the following steps: 1. Manually puts A- or B-side into asynchronous mode (Table E starts with A-side), and takes the opposite side offline. 2. Repairs or updates to components of the offline system are made. 3.
Table E. System Update of Hardware/Software, Starting from Default Mode (Continued) 5 6 Press CC1 A once to synch A to B. This is done so that currently logged on KBDs will not go offline whenever control is switched to the B-side. CC1 A Press and hold CC1 B for two beeps (forces B-side to Async mode; A-side is still online, but not synched. CC1 B [2 beeps] 7 Press KVD A button, so that diagnostic tools are available for the A-side update. 8 “Ctrl + Q” keypad operation on A-side takes it offline.
SECTION 4.0: APPENDICES INTRODUCTORY REMARKS All appendices (except Appendix 4.5 ), focus on specific installation issues or various situations of interest to the user. Each deals with a separate aspect of integrating the current HS into the described system environment. For completeness, all possibilities of interest are listed here, although some of the topics have already been discussed thoroughly in the manual. Appendix 4.5 extends the brief data cable parameter statement made in Section 1.
APPENDIX 4.2 HS UPDATE (Previous Model of Hot Switch Installed) The previous model of the hot switch has existed for some time. Those acquainted with its operational characteristics know the uses and characteristics of a hot switch. This is an advantage, on one hand, compared to those not so acquainted. On the other hand, that advantage is somewhat eroded by the fact that there are some major differences involved in the hookup and use of the new HS.
Figure A4-1 also highlight the two major differences between the current and previous hot switch: 1. COM Port Flexibility The COM 1 and COM 2 Destination ports for the previous hot switch allowed for the connection of the PC w/MGR and, if desired, an ASCII Control Device interfaced via a Pelco DT, for example. The same relationship can be repeated in the current HS via the COM 1 and COM 2 Destination ports (located on the CPS) for the devices just mentioned, which are shown in Figure A4-1.
APPENDIX 4.4 HS AND NETWORK-INTERFACED CONFIGURATIONS Below are node-specific connections of NIU configurations, where each node is hot-switched. Note the following points, which are also reflected in Figure A4-2: 1. Each CC1 port connection to the HS (on its respective node) stays at port 5 (standalone configuration) while the NIU connection (via the SEU) is connected to port 6 on each CC1. 2.
Interfacing network nodes with a hot switch (illustrated in Figure A4-2) can be extended to include the NIU itself. Figure A4-3 keeps the same node structure shown in Figure A4-2, except that now a hot switch interfaces the NIU. Note that the equipment numbers for hot switches contained in the respective port definition files for the NIU and the Nodes themselves are different.
APPENDIX 4.5 DATA CABLE PARAMETERS NOTE: For short distances that exceed the cable length supplied, you might consider the use of CAT 5 cable (for distances up to 300 feet). This cable is RS-422 compliant (up to the length mentioned) and is used primarily for Ethernet connections within networks. Moreover, it is readily available (because of demand) and cost is reasonable (because it is less difficult to manufacture).
Remote Hookup of the CM9760-KBD The 9760 keyboard comes with associated cables and a CM9505UPS (universal power supply) to supply the 12V needed to power the keyboard. The standard hookup for the keyboard to the matrix switch (CC1) is shown in Figure A4-5.
For remote installation of the keyboard, the user must supply a cable of appropriate length that supports the TIA/EIA-422-B (RS-422) communication standard. The example in Figure A4-6 shows a keyboard placed 2,000 feet (610 m) from the CC1 via the user-supplied cable. Junction boxes (phone boxes) are used to facilitate the RJ-45-to-cable connection points at either end of the run.
In either case, Pelco recommends using a cable similar to Belden 9843, that meets or exceeds the support requirements for TIA/EIA-422 applications. TableA4-A is taken directly from the FULL TECHNICAL SPECS page in Belden’s Cable Catalog located on their company web site. Table A4-A.
