Chapter 1: Product Description
This manual contains the information required to install and use the EMC-FDM floppy drive
expansion module.
The EMC-FDM is a floppy disk unit and also includes a standard male 9-pin serial port and a
standard female 25-pin parallel port.
Due to the size of the floppy drive unit, the EMC-FDM uses a double-wide EXM form factor.
The EMC-FDM is the same size as the EMC-PS50 unit, and is designed to mount on the right
side (opposite the EMC-PS50) of an EMC chassis. One such chassis available from Industrial
Computer Source is the EMC-CH6D.
The EMC-FDM is fully software configurable via the setup screen allowing the user to enable
or disable the card and configure the I/O address and interrupt level for each port.
WARNING!
Do not plug in any cable or connector into the front panel connectors while the EMC-
FDM is powered up. This unit is not designed to withstand potential damage that could
arise from fluctuations in power. Never plug in a serial or parallel device, keyboard,
transceiver, or other component while the system is turned on.

Chapter 2: Installation
Chapter 2: Installation
Before installing the EMC-FDM, unpack and inspect it for shipping damage.
• Do not remove the module from its anti-static bag unless you are in a static-free
environment. The EMC-FDM, like most other electronic devices, is susceptible to
ESD damage. ESD damage is not always immediately obvious, in that it can cause a
partial breakdown in semiconductor devices that might not immediately result in a
failure.
• Ensure that the installation process as described herein is also performed in a static-
free environment.
Insertion in an EMC Chassis
Insertion of the EMC-FDM into an EMC chassis is straightforward. Locate the double-wide
open card guides at the far right of the carrier (opposite the power supply) and insert the EMC-
FDM into the backplane connector. Firmly press the EMC-FDM front panel to ensure that the
module is properly seated in the backplane, then secure it with the supplied screws and nylon
washers.
• Make sure that power to your system is off. The EMC-FDM is not designed to be
inserted or removed from a live system.
• When inserting the EMC-FDM, avoid touching the circuit board, and make sure the
environment is static-free.
• Insert it with adequate continuous force rather than tapping or hammering on it.

EMC-FDM Manual
Configuring the BIOS Setup
The EMC-FDM is electrically an EXM device, and is configured like any other EXM module.
The configuration data in the EPC to which the EMC-FDM is connected needs to be modified
to recognize and enable the module. After installing the module, turn on the system and boot it
up. From the command line, invoke the BIOS setup function by pressing the CTRL-ALT-ESC
keys simultaneously.
Enabling the EMC-FDM Module
Once in the setup function, a menu displays specifying which function keys are available for
further configuration. Press the F2 function key to invoke the EXM Setup Screen. Informa-
tion similar to the screen shown in Figure 1 below displays:
ID OB1 OB2
Slot 0 FF 00 00
1 EC 01 00
2 7C E1 00
3 DC F5 00
4 F5 05 00
5FA 25 00
Figure 1: EXM Setup Screen
This screen displays the EXM configuration data (in hexadecimal) stored in nonvolatile memory.
The EPC uses this information at power-up to recognize and configure each installed EXM.
The displayed data shows SLOT, ID, OB1 and OB2 information. These are defined as follows:
SLOT Indicates the slot in which the EXM is installed. See Figure 2 below to
determine which slot the EXM occupies.

Figure 2: EXM Slot Numbering
The EMC-FDM occupies the two open slots on the far right of the chassis.
ID is a hard-wired ID value. Each EXM type has a unique ID value.
OB1/OB2 are two bytes of option information.
Note that all slots are listed even if the system configuration does not have all the possible
EXM slots. All slots not occupied by an EXM module should show an ID ofFF and OB1/OB2
of 00 00 indicating that no EXM is present.
To add or change an EXM configuration, use the cursor keys (arrows) to move between the
fields on the screen. Move the cursor to the appropriate slot entry and type in the correct value.
The ID for the EMC-FDM should be set to 7C.

OB1 is defined as follows:
Parallel Port
I/O Enable Parallel Port Enable Printer Port Select COM Port Interrupt
COM Port
Base
Address Card Enable
(bit 7) (bit 6) (bit 5) (bits 4, 3) (bits 2, 1) (bit 0)
1 = Enable
ouput 1 = Enable 1 = 378 IRQ7 00 = Disabled 00 = Disabled 1 = Enable card
0 = Enable
input 0 = Disable 0 = 278 IRQ5 01 = IRQ3 01 = 2F8h 0 = Disable card, IRQs
10 = IRQ4 10 = 3E8h
11 = IRQ9(2) 11 = 2E8h
Table 2: OB1 Register.
Parallel port In/Out - Normally set to 1 to enable output to the parallel port. Set to 0 to input
data from a parallel device such as a scanner. Note that the DIR bit, which is bit 5 of register
27Ah or 37Ah, must be set to 1 via application software before the parallel port accepts input.
Bit 7 has no effect when bit 6 = 0.
Parallel port enable - If 0, disables the parallel port registers and interrupt. A value of 1
enables the port.
Printer port select- If set to 1, selects a base address for the parallel port of 378h (LPT1:) and
interrupt IRQ7. If clear, selects 278h and IRQ5.
COM port interrupt select - Encoded as follows:
00 Disabled. COM port uses no interrupt but can be written to.
01 Use IRQ3 (this is normally COM2)
10 Use IRQ4 (this is normally COM1)
11 Use IRQ9
COM port base address and enable - Encoded as follows:
00 Disabled. COM port will not respond.
01 Base address 2F8. This is normally COM2.
10 Base address 3E8. This is normally COM3.
11 Base address 2E8. This is normally COM4.
Card enable- CDEN must be set to 1 to enable the EMC-FDM. Note that setting CDEN to 0
disables all access to the registers, as well as disabling all interrupts.

Chapter 2: Installation
OB2 is defined as follows:
Reserved Floppy Drive Enable
(bits 7-2) (bit 1) (bit 0)
111111 1 = default 1 = Enable floppy drive, DRQ and IRQ
0 = Disable floppy drive
Table 3: OB2 Register
Bit 1 - Reserved for future use.
Floppy Drive Enable - Use to enable or disable the floppy drive. Please note that only one
floppy drive controller per system can be enabled at any one time. If the EMC system requires
an EXM-16 or an EXM-MX running with the EXM-FDM, disable all but one floppy drive.
Floppy Drive Setup
Refer to the pertinent EPC manual for a detailed description of how to change the configura-
tion information stored in battery-backed RAM. In most cases, invoke the BIOS setup func-
tion by using CTRL-ALT-ESC from the DOS command prompt. Be sure to define drive A: as
a 1.44M 3.5 inch drive.
Port Conflicts
Avoid interrupt and address conflicts due to multiple serial or parallel ports with the same
address or interrupt. Be sure to either disable unused serial or parallel ports, or set them to a
value that does not conflict with other ports in the system.
Note that in general attaching a mouse to a serial port only works on COM1 or COM2.

Chapter 3: Operation
The EMC-FDM provides a 3.5" floppy disk drive and controller and both a standard 25-pin
parallel port and a 9-pin DTE serial port. Both ports are implemented using a single VLSI
VL16C452chip. The VL16C452 providestwo serial channels, channel 0 and channel 1. Channel
0 is not used.
This chip does not support HDLC and SDLC protocols. For detailed programming informa-
tion, see the appropriate VLSI Technology data manual.
The floppy disk is controlled by a 37C65C floppy disk controller, identical to other Industrial
Computer Source products.
The floppy drive supports both 1.44 Mbyte and 720 Kbyte 3.5" diskettes. The drive select is set
as the A: drive.
Connectors
The parallel printer port is a standard female DB-25 with the pin-out defined as follows:
