1.1 Introduction
This chapter describes the CA386-N1 hardware. It lists specifications for I/O, power, and mechanical dimensions, covers communications issues, and describes all the jumpers and connectors and their pin-outs. A schematic and a parts list are also included at the end of the chapter. Figure 1.1 is a simplified block diagram of the
CA386-N1.

Specifications
1.2 Specifications
The CA386-N1 is an Intel i386EX based single-board computer with integrated LonTalk interface. Hardware
specifications are as follows:
•25MHz Intel i386EX Processor
•256K, 1M, or 4M SIMM DRAM
•512K Flash EPROM
•NEURON 3120 with MIP Firmware installed
•LonTalk Transceiver: TPT/XF-78, TPT/XF-1250, or FTT-10
•2 RS-232 asynchronous serial ports (COM1, COM2)
•RS485 option on COM1
•8 TTL-level digital I/O
•3 programmable counter/timers
•Battery-backed real-time clock (optional)
•8/16-bit PC/104 Bus
•Power Requirements: single +5 volt operation (+12V, -12V required if certain PC/104 peripherals are
•Dimensions: 4” (10.2mm) x6.25”(15.9mm) x approximately 1/2”
•Operating Temperature: 0-70 C
1.3 Related Documentation
The following documents are useful for a full understanding of the CA386-N1 system:
•Intel386EX Embedded Microprocessor Hardware Reference - available from Intel Corporation Liter-
ature Sales, P.O. Box 7641, Mt. Prospect, IL 60056-7641
•LONWorks Technology Device Data - available from Motorola Literature Distribution Center, P.O.

1.4 Power
Power is supplied to the CA386-N1 through either connector J7 or J10. There are lines on both J7 and J10 for the
following voltages:
•+5VDC
•+12VDC
•-12VDC
•Gnd
•Vin - Variable Voltage Input for use with a power supply or converter
1-2CA386-N1 REFERENCE MANUAL
The board is designed to be powered in one of two ways:
•“Raw” power and ground connected through J7-Vin, and a regulator attached to J10 which takes the
raw power in and produces +5V (and +12V, -12V if required).
•+5V (and +12V, -12V if required) supplied through J7; J10 unused.
The first method is useful for providing an internal power supply or converter in an enclosure.
1.5 Connectors and Jumpers
1.5.1 Overview
Figure 1.2 shows the locations of all the connectors and jumpers on the CA386-N1. The following sections
describe each jumper and connector in detail. Note that each connector or jumper shown below is oriented such
that the power and network connectors (J7, J9) are at the “top” of the board. Also note that the reference designators (labels) are shown in their actual location and orientation relative to the connector or jumper.
