 SUSIC (Parts List/Assembly Instructions)
This new Super Universal Serial Interface Card provides an upgrade of the original design USIC - the one using the 68701 chip. The new Microcontroller based SUSIC plugs into an I/O motherboard, as does the original USIC, for interfacing up to a total of 64 digital input and digital output cards. The SUSIC is smaller, faster, much more capable than the original USIC.

  SMINI (Parts List/Assembly Instructions)

This new Super Mini-node card combines all the advanced features of the new SUSIC with 48 output and 24 input I/O lines. It's really a single card providing a complete standalone serial node with 72 I/O lines.

PICTURE COMING SOON CON72

These are the shell connectors and crimp pins needed to connect 72 wires to a SMINI node.  They are only available as a "kit" (you must crimp them on the wires yourself).

PICTURE COMING SOON DIN
Digital input card. A general purpose card with 24 input pins, or lines, that can be used to monitor the on and off status of external devices. Acting through the DIN card, the application software can determine the status of the 24 separate external devices.

PICTURE COMING SOON DOUT
Digital output card. A general purpose card with 24 output pins, or lines, that can be used to control devices on your railroad. Acting through the DOUT card, the application software has separate control of each of the 24 lines and thereby can separately turn the external devices on and off.

  DIN32 (Parts List/Assembly Instructions)

This new digital I/O card incorporates 32 input lines. The resulting smaller card provides 33% more I/O than the previous DIN card while plugging directly into the I/O motherboard. Each card is DIP switch addressable up to 64 cards per node. The card includes optional built-in input line filtering.

  DOUT32 (Parts List/Assembly Instructions)

This new digital I/O card incorporates 32 output lines. The resulting smaller card provides 33% more I/O than the previous DOUT card while plugging directly into the I/O motherboard. Each card is DIP switch addressable up to 64 cards per node. Drive capability has been increased with less current draw per card. Each of the card's four 8-bit ports is separately configurable to support either standard current sinking or current sourcing.

  TEST32 (Parts List/Assembly Instructions)

This new digital I/O card incorporates 32 output lines. The resulting smaller card provides 33% more I/O than the previous DOUT card while plugging directly into the I/O motherboard. Each card is DIP switch addressable up to 64 cards per node. Drive capability has been increased with less current draw per card. Each of the card's four 8-bit ports is separately configurable to support either standard current sinking or current sourcing.

  RS485 (Parts List/Assembly Instructions)

This new RS232 to RS485 conversion card replaces the previous RS422 conversion card. Plus and minus 12Vdc power is no longer required as everything works off a standard +5Vdc supply connection. The new RS485 card retains the same advantages use of the two data direction monitoring LEDs and works with both the RS422 and RS485 standards. Line termination resistor networks are included as an integral part of the card's design. 

  IOMBX (Parts List/Assembly Instructions)

This newly expanded I/O Motherboard provides 15 card slots as compared to the 13 provided by the previous IOMB. The 40-pin header, included with the IOMB, is deleted from the IOMBX in favor of adding the additional card slots. Thus, the IOMBX is the preferred motherboard for all USIC applications while the IOMB is still required when using the IBEC.

  OD (Parts List/Assembly Instructions)
Optimized detector. The OD is a small card that senses current flow in a section of track to determine block occupancy. The output of the card can drive LEDs or relays directly but most importantly connects directly to a line on an input card. A built-in potentiometer and test LED are used to adjust the circuit's sensitivity. Typically at its maximum sensitivity setting, a dampened finger placed across the track will register as occupied.

  DCCOD (Parts List/Assembly Instructions)

DCC optimized detector. The DCCOD is a new card introduced with this handbook specifically designed for DCC equipped railroads. If you already have ODs, you can use them with DCC but using the DCCOD provides a somewhat easier approach. To operate properly, the DCCOD requires a continuous flow of input pulses as supplied by DCC. The DCCOD will not work with straight DC layouts and therefore is not applicable to MBC, WBS, CCC or CBC operation. It does work, however, with Railcommand, CTC-80 and CTC-16 equipped railroads. The output of the DCCOD has the same drive capability as the OD. It also incorporates the built-in potentiometer and test LED for adjusting the circuit's sensitivity. Like with the OD, a dampened finger placed across the track will register as occupied.

  ODMB

Optimized detector motherboard. The ODMB is a circuit card with connectors wired in parallel whereby up to 12 OD or DCCOD cards can be inserted. Using the ODMB cuts down on the wiring requirements and also enables the detectors to be distributed around the railroad. The power supply connections to the ODMB are slightly different depending upon whether you are using ODs or DCCODs. If more than 12 detectors are desired at any location, multiple ODMBs can be connected together.

  SMC12 (Parts List/Assembly Instructions)

Switch motor control driver. Each SMC12 card can control up to 12 low-current stall-type switchmotors. It does this by employing 6 identical circuits per card where each circuit controls 2 stall-motors. The big advantage of using the SMC12 card is that only one C/MRI output line is required per Tortoise machine. When the input line is high, polarity is applied to the switch motor in one direction and when low the polarity is applied in the opposite direction. The SMC is a great way to drive Switchmaster and Tortoise machines either with or without the computer.

PICTURE COMING SOON SM2 (Parts List/Assembly Instructions)

Twin-coil switch machine driver using single input line. Like the SM1, the SM2 controls a single twin-coil switch machine. Since a switch machine is a binary device, i.e. it has two states, being either in normal or reverse positions, one control line should be all you need for control. The SM2 card's unique circuitry provides this capability. When the input transitions from low to high, one coil is energized; from high to low the other coil is energized. A built-in timing function controls the duration time that the coil is energized. The circuit's advantage is that it cuts the number of control lines required from the computer in half. Its disadvantage is that if you elect to throw a bunch of turnouts simultaneously you need a pretty hefty power supply, plus the circuit is more sensitive to electrical noise, possibly causing an occasional unwanted throwing of the turnout. On the positive side, I have never had a customer say that they experienced unwanted turnout throws with the SM2 caused by electrical noise.

  CRCCD7-7

Cab relay card - 7 cabs. This card is used to automatically assign any one of up to seven cabs to a block. It replaces the conventional block toggle or rotary switch used with manual block control. You need one of these cards per power block when implementing Computer Cab Control. Which relay is energized by the C/MRI software determines which cab has control of the block.

  CMB12

Cab motherboard. A circuit card with connectors wired in parallel whereby up to 12 CRC cards can be inserted. Since the CMB contains the required cab bus connections it cuts down on the wiring requirements plus it enables the relay cards to be more easily distributed around the railroad. If more than 12 CRCs are desired at any location, multiple CMBs can be connected together.

PICTURE COMING SOON CDC- NO PANEL

Cab display card. This card can be used to add an optional block status display as part of a control panel track diagram when using CCC. The card incorporates a single-digit numeric LED for indicating the cab number assigned to the block, two direction LEDs to indicate the direction of travel for the cab in the block, and a block occupation LED.

PICTURE COMING SOON RSSD (Parts List/Assembly Instructions)

Remote searchlight signal driver card. This card is set up to drive four 3-color aspect searchlight signals using outputs from a conventional DOUT or COUT24 card. The SSD connects between the conventional output card and the signals much like the SMC card connects between a conventional output card and Tortoise switch motors. The SSDOUT card mentioned in previous versions of the Handbook is not being produced in favor of using the SSD with the DOUT.

PICTURE COMING SOON WRAPCA24

Wrap around cable, 24 pins. A wrap around cable for testing 24 pin devices.

PICTURE COMING SOON CON24

These are the shell connectors and crimp pins needed to connect 24 wires to a SMINI node.  They are only available as a "kit" (you must crimp them on the wires yourself).

PICTURE COMING SOON SSD (Parts List/Assembly Instructions)

Searchlight signal driver card. This card is set up to drive twelve 3-color aspect searchlight signals using outputs from a conventional DOUT or COUT24 card. The SSD connects between the conventional output card and the signals much like the SMC card connects between a conventional output card and Tortoise switch motors. The SSDOUT card mentioned in previous versions of the Handbook is not being produced in favor of using the SSD with the DOUT.

PICTURE COMING SOON WRAPCA32

Wrap around cable, 32 pins. A wrap around cable for testing 32 pin devices.

PICTURE COMING SOON CON32

These are the shell connectors and crimp pins needed to connect 32 wires to a SMINI node.  They are only available as a "kit" (you must crimp them on the wires yourself).
