Introduction

The PCM-53E52 is a compact Half-EBX board with PC/104Plus, SSD, Ethernet, and four COM ports.

Unlike other compact Half-EBX boards, the PCM-53E52 has an optional Analog and Digital I/O Daughter

Board, allowing for data acquisition and greater flexibility.

The PCM-53E52 features a low power AMD® ELAN-SC520 133Mhz processor (no fan required, P120

equiv.). This compact Half-EBX board has on board, 16MB of SDRAM memory standard. A 32MB to

128MB memory upgrade option is also available as is a DiskOnChip® 2000 (DOC) solid state flash disk

(no moving parts). The PCM-53E52 can be connected onto a network using the Realtek® RTL8139C

10/100Base-T Ethernet controller and onboard RJ-45 connector. In addition, the PC/104Plus connectors

provide both ISA and PCI connectivity.

The PCM-53E52 offers three RS-232 serial ports, one RS-232/422/485 serial port, and a parallel port that

supports SPP/EPP/ECP parallel modes. This board includes a mini-DIN keyboard/mouse connector, an

onboard 34-pin FDD interface that supports two floppy disk drives, and an onboard 44-pin EIDE interface

that supports two EIDE devices. The PCM-53E52 is 5.75" in length and 4" wide, making it a great fit for

harsh environment and limited-space applications.

The optional Analog and Digital I/O Daughter Board adds micro-controller capability with the power of a

PC. The I/O daughter board includes 16, General Purpose I/O lines and eight high current sink outputs on

a standard I/O Rack compatible 50 pin header. This board also includes: 16 channels of A/D with 10

or12-bit resolution, and four channels of D/A with 12-bit resolution. In addition, the I/O daughter board

supports up to a 24-key keypad and is capable of driving up to a 40 x 4 character and graphic LCD

displays.

PCM-53E52 Configuration

Jumper & Connector Descriptions

The PCM-53E52 comes factory configured and ready to operate. In the event that jumpers need to be

verified or modified this section provides the information required, including instructions on setting

jumpers and connecting peripherals, switches and indicators. Be sure to read all the safety precautions

before you begin any configuration procedure. See Appendix A for connector pin-outs and Appendix B for

Jumper Settings.

Determining Board Configuration

The board number can be used to determine what options are populated.

For example:

PCM-53E52-0011 is a board with 16mb of ram, Ethernet and PC/104+

This is found by decoding the last 4 numbers as follows:

0XXX is the standard 16mb of onboard memory

1XXX is the upgrade to 32mb of onboard memory

2XXX is the upgrade to 64Mb of onboard memory

X0XX is a reserved designator

XX0X is the Ethernet option designator, 1 for no Ethernet, 0 if present.

XXX0 is the designator for PC104+, 1 means the PC104+ connector has not been populated.

Determining How Much Memory is Onboard

The following information is to help assist in calculating how much ram your board has on it.

This information pertains to the onboard chips U4 and U5:

16meg system =2pcs of (8mB) 4 Meg x 16 Quad bank, 3.3V-- MT48LC4M16A2TG-75

32meg system =2pcs of (16mB) 8 Meg x 16 Quad bank, 3.3V-- MT48LC8M16A2TG-75

64meg system =2pcs of (32mB) 16 Meg x 16 Quad bank, 3.3V-- MT48LC16M16A2TG-75

These part numbers are Micron Technology parts and may be substituted with equivalent chips by

another manufacturer.

Powering Up the PCM-53E52

The PCM-53E52’s power connector (CN1) is a standard floppy, four-pin type connector commonly found

on most PC type power supplies. The PCM-53E52’s logic only requires 5 volts DC. The 12v pin (HDR6

pin 4) is routed to the PC/104 connectors and may be used by some PC/104 expansion cards. The pin-

out for the HDR6 power connector is as follows:

Pin Signal

1 +5 V

2 GND

3 GND

4 +12 V

Remember before powering-up the PCM-53E52 make sure the DOC is correctly orientated, firmly

seated and check any cables to make sure that plugged on and correctly in relation to pin 1.

Note: The PCM-53E52 requires less than 2 amps which is not enough current to load the main switcher

in some larger PC power supplies (this can be verified with a voltmeter measuring the 5-volt supply). If

this is the case you can try to load the power supply by adding 5-volt devices, or order a compatible

power supply from EMAC.

Ethernet

The PCM-53E52 utilizes the RTL 8139 10/100 BaseTX full duplex Ethernet chip and terminates to a

standard RJ-45 connector (JK1). It can be connected straight to a Hub, Switch or directly to another

computer via a crossover Ethernet cable. Link and Activity (Rx/Tx) LEDs (LD2) are provided to monitor

network activity.

Serial Ports

The PCM-53E52 is equipped with four serial ports. All four serial ports are standard X86, 16550, 16 byte

FIFO UARTS.

COM1 is set to be RS232 and is configured by default to 3F8H using IRQ 4. Availability is via the DB9

(CN1) connector on the edge of the board.

COM2 is jumper configurable to run RS232 or RS422/485 and is set by default to I/O address 2F8H using

IRQ 3. This comport is available via a DB9 connector (CN2). The mode is switched using JP4, if the

jumper is present it will run RS422/485.

COM3 and COM4 are both configured as RS232 ports. These are available to the user on connectors

HDR7 & HDR5 respectively. The default I/O address and IRQ for COM3 is 3E8H using IRQ 5 and the

default I/O address for COM4 is 2E8H using IRQ 11.

NOTE: COM4 DOES NOT OFFER HANDSHAKING AND IS LIMITED TO RXD AND TXD DUE TO PIN

FUNCTION TRADEOFFS AT THE SUPER I/O CHIP. SELECT FUNCTIONS FROM COM3 AND COM4

SHARED THRU ONE INTERFACE DRIVER CHIP.

Keyboard/Mouse

The PCM-53E52 is equipped with a keyboard and mouse interface. Both the keyboard and the mouse

utilize the same PS/2 connector (JK1) through the use of the included Y cable. Though a standard PS/2

keyboard can be plugged directly into the connector, to be able to use both a keyboard and mouse you

must use the Y adapter cable or a serial mouse.

Disk-On-Chip Flash Disk

The PCM-53E52 does not come with a DOC flash drive chip installed by default, but one can be ordered

from EMAC and installed by the user or integrated at the time the PCM-53E52 is ordered.

The DOC is a solid state flash disk and as such is extremely rugged when compared to a conventional

hard drive. The DOC is a paged memory device and is mapped at segment address D000 Hex, and by

use of the device’s firmware emulates a hard drive. Thus most operating systems will be able use the

device similar to a hard drive.

Warning:Be extremely careful when installing the DOC into its socket. Plugging

it in backwards, and turning on power, can destroy the DOC and damage the

PCM-53E52 rendering both inoperable! Any information on the DOC will be

unrecoverable at this point.

Always double-check the orientation of the DOC when it has been removed from

the board and reinserted, prior to turning the power back on.

Parallel port

The PCM-53E52 comes with a Standard Parallel port interface, This is available to the user via a 26-pin

header (HDR3) and included female DB25 cable.

IDE connector

The PCM-53E52 is equipped with a standard IDE interface available to the user via the standard 40-pin

header (HDR2) on the board. A standard hard drive cable is included.

Floppy Drive connector

The PCM-53E52 is equipped to operate a standard 3.5” 1.44Mb floppy drive via the standard 34-Pin

header (HDR5). A standard floppy drive cable is included.
