CTI Products, Inc. NCB/IM User Guide QUICK-START GUIDE This Quick Start Guide provides a concise series of steps to get a pair of the NCB modules “up and running” quickly so that initial operation may be confirmed. It is important that all LONW ORKS devices attached to the “NETWORK” connector of any one NCB module use the same network transceiver . See “LONW ORKS NETWORK TRANSCEIVERS” in section “1. INTRODUCTION”. In the following steps, identify the two units as “NCB Unit 1” and “NCB Unit 2”.

CTI Products, Inc. NCB/IM User Guide 1. INTRODUCTION WHAT IS AN NCB/IM UNIT? Read this section to learn the general function and capabilities of an NCB Router The Network Combiner NCB/IMTM Module is a wide-area router with an internal modem for LonWorks networks. The NCB/IM unit is used in pairs to connect LONW ORKS networks real-time, spanning distances from building-wide to worldwide.
CTI Products, Inc. NCB/IM User Guide NCB units are available with an option for LONW ORKS network transceiver type. The ordering code on the rear of the NCB lists the installed options. This ordering code is of the form: NCB/IM-Txxx-xx, where ‘T’ indicates the transceiver type. The following LONW ORKS network transceiver options are available: A = FTT-10A K = SMX RS485 B = TPT/XF-78 M = SMX PL22 C = TPT/XF-1250 X = None (SMX ready) Line Port The internal modem in the NCB/IM module uses proven V.
CTI Products, Inc. NCB/IM User Guide Router Function The router contained in each NCB module may be configured as a repeater, bridge, or configured router. The easiest configuration is as a repeater, where all messages which enter the NCB module (via any of the three data sources described above) are simply passed to the other two sources, regardless of the domain, subnet/node, or group destination address. A bridge only passes messages that match one of the two domain IDs configured on the router.

CTI Products, Inc. NCB/IM User Guide CMD Button This button can be used to temporarily enable the Auto Answer function in Dial-up mode. This is useful if Auto Answer mode has been inadvertently disabled on a remote NCB. When this occurs, and a connection with this remote unit is broken, it will no longer automatically answer an incoming call. To re-enable Auto Answer mode, proceed as follows: Press and hold the “CMD” button on the remote NCB Press and release the “RESET” button on the remote NCB.

CTI Products, Inc. NCB/IM User Guide 2. SETUP AND OPERATION STEP 1. MOUNTING Follow the steps in this section to setup an NCB Router for the first time Non-slip rubber feet are included on all NCB modules to allow them to conveniently rest on any horizontal surface. Four 6-32 threaded holes are also available on the bottom of the module to allow bolting of the module in any convenient orientation. WARNING: Care should be taken to limit protrusion of the screw into the module to no more than 0.
CTI Products, Inc. NCB/IM User Guide Setting the Internal Modem Configuration (Switches 1, 2, 7, and 8) Will a Dial-Up line be used for this Network? ? If Manual or Perpetual Dial-up Mode is required, see “DIAL-UP CIRCUITS” following in this section. If using a leased telephone line, see “LEASED-LINE CIRCUITS” following in this section. Tutorial . . .
CTI Products, Inc. NCB/IM User Guide 2) OPTION A Switch 7 is used to set the transmit level from the modem and should be normally left in the UP position. If two NCB units are to be connected “back-to-back” in Leased-Line mode with only a short cable between the “LINE” connector on each unit (in lab test situations, for instance), Switch 7 must be set to the DOWN position in order for the two modems to connect properly.
CTI Products, Inc. NCB/IM User Guide Telephone Line Connection LINE The telephone circuit connection must be made using the “LINE” connector See APPENDIX C for connector type and pinout. Dial-Up A dial-up connection uses a 2-wire connection scheme to a standard telephone circuit. A standard telephone cord can be used.
CTI Products, Inc. NCB/IM User Guide utilizing a portion of the connection bandwidth. This utilization is dynamic and only consumes bandwidth when audio is detected into the “AUDIO” connector. NOTE: Data throughput across the modem channel is decreased by 7200 bits-per-second when audio input is detected at either handset.
CTI Products, Inc. NCB/IM User Guide Commissioning the NCB with LonMaker for Windows Commissioning each NCB in a network with LonMaker for Windows involves commissioning two different network devices, both contained in the single NCB enclosure: a standard LONWORKS router, and the control neuron. Since the standard LONW ORKS router portion of an NCB router interfaces a LONW ORKS channel to a Telephone (WAN) channel, it requires connection to two channels on the LonMaker drawing.
CTI Products, Inc. NCB/IM User Guide Specify a Location string and Description, if desired. “Ping Interval” can be set as desired, however should be set to “never” for remote NCB routers which are not connected full-time (for example, those connected via dial-up telephone lines). Click NEXT to continue. Specify desired advanced router properties. Router Type : Configured is recommended. Click FINISH to complete the “New Router Wizard”.
CTI Products, Inc. NCB/IM User Guide STEP 5. CONTROLLING THE WAN CONNECTION At this point, the “local” NCB (the one connected to the LonMaker for Windows NSI) has been configured and fully commissioned for use. This last step involves making a connection to the “remote” NCB via the Telephone (WAN) channel.
CTI Products, Inc. NCB/IM User Guide 3. NETWORK VARIABLE (NV) CONTROL TYPICAL NV BINDINGS This Section contains details of Network Variables and Bindings All commands sent to the NCB module are carried on the LonTalk network in the form of Network Variables bound to the Control Neuron processor inside the NCB module (connected to Side A of the internal router). This section details the Functional Blocks (objects) and the network variables of each.
CTI Products, Inc. NCB/IM User Guide The example in Figure 6 uses multiple Directory Objects with multiple Modem Controller Objects.
CTI Products, Inc. NCB/IM User Guide Network Variables Dial String (Input) C Language Syntax network input SNVT_str_asc nviDialStr1; network input SNVT_str_asc nviDialStr2; Usage A non-null string sent to this input network variable while the current modem connection state is TEL_NOTINUSE causes the modem to go off hook, wait for a dial tone, then perform a dialing sequence using the provided character string.
CTI Products, Inc. NCB/IM User Guide Connect Status (Output) C Language Syntax network output SNVT_telcom nvoCnctStat1; network output SNVT_telcom nvoCnctStat2; Usage This output network variable provides the current state of the modem connection process.
CTI Products, Inc. NCB/IM User Guide Request Dial String (Output) C Language Syntax network output SNVT_char_ascii nvoReqDialStr1; network output SNVT_char_ascii nvoReqDialStr2; Usage This output network variable is associated with Perpetual Dial-Up Mode (see Tutorial “Which Modem Mode Should Be Used” in section “2. SETUP AND OPERATION”) and is used when the Directory Object storing the telephone number (to be dialed) belongs to a node other than the call-originating NCB.

Refer to Technical Note TN025 for more information on configuration of the router with standard network management tools such as LonBuilder, LonMaker, LNS, and others. The SETRTR program requires a network interface to be connected to the personal computer.
CTI Products, Inc. NCB/IM User Guide APPENDIX B. MOUNTING OPTIONS Wall mount and EIA 19” rack mount kits are available as options for the NCB from CTI Products, Inc. The wall mount kit includes brackets to allow a single NCB module to be mounted to any flat surface. The rack mount kit includes an adaptor allowing up to three NCB modules to be mounted in a single rack unit height. Rack Mount Option The rack mount option allows up to three NCB modules to be mounted in a one rack unit height (1.
CTI Products, Inc. NCB/IM User Guide To attach a module to the rack adaptor, and then mount the rack adaptor into the rack, follow the steps below. WARNING Do not allow the PC board to slide out of the housing when the front panel is removed. If it does, DO NOT slide the PC board back into the housing from the front of the module. Doing so may damage the unit, causing the unit to malfunction when powered on. Doing so will void the unit’s warranty.
CTI Products, Inc. NCB/IM User Guide Wall Mount Option The wall mount option allows an NCB module to be mounted to any flat surface. The NCB module has four screw holes on the bottom. Simply attach the two mounting plates to the bottom of the module using the four flat-head screws provided with the wall mount kit. This assembly is then attached to the flat surface with userprovided fasteners. Figure 9 shows a dimensioned view of the wall mount installation.
