Quick Reference

Introduction

The Mobile Gateway Plus 486 (MG+ 486) is a small, rugged
computer used as a platform for in-vehicle communications and
connectivity by Symbol portable data terminals. It provides wireless
network communications and RS-232 flexibility.

The MG+ 486 supports MS-DOS, GS-DOS and Pharlap RTOS
operating environments using industry standard protocols. It is
available with an 80486 processor.

Input/Output Ports

The MG+ 486 has up to 5 external serial ports and one I/O port on
the rear panel of the unit.

COM1

This RS-232 DTE serial port uses a 9-pin male DSUB connector.
The COM1 port can be used to interface with devices such as
portable terminals and laptop PCs, and connects to an RS-232 port
on a host computer using a null modem cable. COM1 also can be
connected to a host console adapter that boots the MG+ 486 into a
mode which redirects the video and keyboard data to COM1, so an
external PC running Procomm or equivalent terminal software can
control the MG+ 486.

MG+ 486

COM2

COM2 is an RS-232 DTE serial port using a 9-pin female DSUB
connector.

12/24VDC

This connector provides the input power for the MG+ 486. The
MG+ 486 operates from 12 or 24 V (9V to 32V) sources.

Options

Several of the following options are also available:

COM3 - Additional RS-232 DTE serial port.

COM4 - Additional RS-232 DTE serial port.

COM5 - DTE serial port that can be configured as either

RS-232, SAE J1708 or TTL level.

I/O - This Input/Output port is a 26-pin high density female
DSUB connector allowing the MG+ 486 to interface with ex­ternal devices. Five digital open collector outputs/inputs are
provided on this port, and three digital inputs that wake up
the MG+ 486. The outputs can be used for external control,
while the inputs can be used for monitoring the state of exter­nal switches or other sensory devices. Three power sources
(unswitched 5V up to 2ma, switched 5V up to 0.5A, filtered/
transient protected input voltage up to 1A) and several ground
pins are also provided. Optional are two 8-bit analog-to-digi­tal channels set up for 0 to 12.5V (voltage range can be mod­ified). Also optional are two 16-bit frequency/pulse counter
channels.

Keyboard - Optional standard XT keyboard connection typi­cally used for development units.

WWAN Antenna - SMA-style connector which provides an in­terface to external radio antenna.

Quick Reference

GPS Antenna - SMB-style connector which provides an inter­face to an external GPS antenna.

S24 Antenna - Reverse BNC style connector which provides
an interface to external S24 radio antenna.

Reset Switch

This is a momentary switch located on the front panel, to the right
of the LEDs. To ensure a clean reset, hold the button down for more
than one second, then release.

Internal Interfaces

Radio Interface

The MG+ 486 can be factory configured for one of the following
radios:

• Ericsson M3090 WAN radio

• RIM 902 WAN radio.

Note: Other radio configurations will be available in the fu-

ture.

The radio is connected to the COM3 port. The optional external
COM3 connector will point to the external connector only when
the radio is not selected.

GPS Interface

The MG+ 486 can be factory configured for a Rockwell Jupiter GPS
receiver. The GPS receiver is connected to the COM4 port. Jumper
headers JP8 and JP9 are used to configure the GPS. The optional
external COM4 connector is connected to the COM4 port only
when the GPS is not selected.

The GPS is backed up by the onboard 3.3V (as long as the main
power is available, or the internal backup NiCd battery is charged).

Quick Reference

PC104 Interface

The MG+ 486 accommodates one PC104 16/8 bit card.

PCMCIA Interface

The MG+ 486 accommodates up to two 5V PCMCIA cards (if both
slots are used, a type 3 card may be installed in the top slot only).
The interface supports hot plug-in.

Backup Battery

The MG+ 486 accommodates an 8.4V 500ma NiCd backup battery
(J2). The backup battery provides power during brownout periods
and backs up the RTCs when main power is not available. The
battery is not user-serviceable.

Installing the MG+ 486

Caution: Improper installation can cause damage to both the ve-

hicle and the MG+ 486. Installation should be per­formed by an experienced technician.

To install the MG+ 486:

1. Select a mounting location that is flat and provides adequate
support and ventilation for the MG+ 486.

Note: The MG+ 486 chassis must be grounded to the vehicle

chassis.

2. Secure the MG+ 486 with appropriate nuts and bolts. Self­locking nuts or lock washers must be used.

3. Connect the power cable.

4. Route the power cable to the battery power source.

5. Connect the V+ wire to the battery power source, splicing a
fuseholder with a 10 amp fuse in-line with the power source.

5

MG+ 486

Note: Locate the fuse as close as possible to the battery power

source.

6. Connect the Vehicle Accessory Power to the vehicle accessory
bus, splicing a fuseholder with a 1 amp fuse in-line with the
accessory power source.

Note: Locate the fuse as close as possible to the accessory pow-

er source.

The accessory bus is the ‘switched’ power source controlled by
the ignition key. Connect the power cable to the power source
using appropriate connectors.

7. Place a CAUTION label on each fuseholder.

8. Plug the circular connector into the +12/24 VDC connector on
the MG+ 486.
