UDC-ME INSTALLATION AND OPERATIONS MANUAL
CHAPTER 1 - INTRODUCTION
1.1 FUNCTIONAL DESCRIPTION
The UDC-ME allows two DTE devices (such as routers) to communicate within proximity of each other. The UDC-ME transmits data bi-directionally at clock rates of 1.2k up to 3.072Mbps between
DTE devices. All clocking and signal crossover are provided within the UDC-ME. The unit is equipped with two interface slots that allow a host of serial interface cards to be utilized. The serial interface cards available are RS-232, RS-422/449, RS-530, X.21, V.35 and HSSI. The Serial Interface cards are interchangeable and may be mixed such as RS-232 to V.35 thus eliminating the need for an interface converter or changing expensive serial cards on a DTE device such as a router.
The UDC-ME is also an excellent choice for testing router-to-router connections via the serial ports.
The unit is an ideal choice for interconnecting your LAN or legacy mainframe equipment.
Installation is fast and simple by setting the internal switches for Clocking, Carrier Operation and
RTS to CTS delay. The UDC-ME has status LED's for each attached DTE device which allows the user to visually confirm the presence of clock and control signals. Also included are options for data or clock inversion.
The UDC-ME utilizes state of the art digital CMOS technology to provide a feature filled product at a very affordable price. Our Field Programmable Gate Array (FPGA) design has allowed us to offer this product with a wide selection of clock rates. This design approach has also reduced the amount of clock jitter for high speed transmissions.
The UDC-ME is housed in a sturdy metal enclosure and operates on 110/220VAC or optional -48V
DC power. Typical MTBF figures are in excess of 150,000 hours of operation.
The UDC-ME has a three year warranty and a 24 hour turnaround on warranty repairs

CHAPTER 2 - PRODUCT OVERVIEW
2.1 FRONT PANEL INDICATORS
A Green LED marked PWR illuminates when AC Power has been applied. Two adjacent sets of Green LEDs, one for PORT A and another for PORT B, illuminate in union with individual port control signal activity. Both Port A and Port B indicators flash in union with
Port A and Port B data interfaces(see section 2.4 Data Interfaces).
2.2 INTERNAL SWITCHES
The UDC-ME has three(3) dip switches. The switches are marked SW1, SW2 and SW5.
Switch SW1 allows the user to set the Clock Rate(s). Switches SW2 and SW5 allow the user to Invert the Clock and force control Signals.
2.3 REAR PANEL POWER CONNECTOR
Located on the back or rear of the product you will find an IEC POWER RECEPTACLE.
The supplied power cord plugs into this receptacle. This receptacle also contains a fuse drawer. Two (2) fuses are located in this compartment. For 110 VAC +/- 10% operation the unit is equipped with slow blow 160ma Fuses. For 220 VAC +/- 10% operation the unit is equipped with slow blow 80ma Fuses.
2.4 REAR PANEL DATA INTERFACE PORTS
Located adjacent to the IEC Power receptacle are the DATA INTERFACE PORTS. The ports are metal stamped PORT A and PORT B. The data interface modules plug into the
UDC-ME main printed circuit board through these openings. The top two screws on the interface module hold the card into place. The front panel Port A and Port B indicators flash in union with Port A and Port B data interfaces.
2.5 CLOCKING
The UDC-ME allows clock rates from 1.2k to 3.072Mbps. The unit has 32 selectable clock rates.
2.6 DATA INTERFACES
The UDC-ME has a host of available DATA INTERFACES comprised of RS-232, V.35,
RS-422/449, RS-530, X.21 and TTL. Each interface module is available in a DCE configuration, the true EIA or ITU recommended connector and female gender is provided.
The V.35 interface modules are MR-34 male, with factory optional DB-25 female. This
option can reduce cabling costs.
2.7
EXTERNAL CLOCK REFERENCE
The UDC-ME allows external timing(if applicable) for applications requiring such via SW2 for either Port A or Port B.
Page 2
UDC-ME INSTALLATION AND OPERATIONS MANUAL
2.8
CONTROL SIGNAL FORCING
The UDC-ME Control Signals are forced on the main printed circuit card located at switch position SW5. ONLY use the Dip Switch to force control signals.
When forcing control signals via SW5, you should see the control signal LED light illiminate on Channel A or Channel B.
While each Data Interface Module has straps(3 pin header) that force select control signals, those straps are for other East Coast Datacom products. It will not harm the unit, but utilizing them can give false LED lights or operation.
2.9
DATA INTERFACE REMOVAL
Disconnect the AC power source from the UDC-ME and disconnect the users data cables from the Data Interface Module(DIM). Located on back panel of the UDC-ME are PORT A and PORT B. Each DIM is plugged into and out of these ports through mating connectors.
Remove the top cover using a phillips screwdriver, then remove the top two screws of the
DIM. Gently pull the module from the UDC-ME housing. It may be easier to hold the edges of the DIM and rock the DIM back and forth as you pull the DIM out of the socket.

3.1 VOLTAGE SELECTION
It is very important to check that the unit is set to the correct voltage setting for your application before applying AC power. Located on the rear of the unit you will find a rotary
110/220 VAC switch. Using a coin or small screwdriver, gently turn the switch to the appropriate power position as required for your installation (110 or 220 VAC).
3.2 VOLTAGE SELECTION FUSES
Located on the back or rear of the product you will find an IEC Power receptacle. This receptacle contains a fuse drawer. Two (2) fuses are located in this compartment. For 110
VAC +/- 10% operation the unit is equipped with slow blow 5 x 20mm 160ma Fuses, E.C.D.
Part # 714000. For 220 VAC +/- 10% operation the unit is equipped with slow blow 5 x
20mm 80ma Fuses, E.C.D. Part # 714001. Spare fuses may be purchased by calling East
Coast Datacom or by contacting the fuse manufacturer: Little Fuse www.littlefuse.com or
Shurter, Inc. at www.schurter.com
Little Fuse Part #'s are: 160ma = 218.160 and 80ma = 218.080
Schurter, Inc. Part #'s are: 160ma = 034.3109 and 80ma = 034.3106
3.3 POWER CONNECTION
Before connecting the UDC-ME to an AC power source the top cover should be installed with the supplied #4-40 screws. AC power is supplied to the unit through a 2.3m (6.6 ft) cord terminated by a grounded 3-prong plug. Select an appropriate location accessible to and within four to five feet of an AC outlet. The AC Power
FUSE
source MUST be grounded or the units warranty will be void.

3.4 DEFAULT CONFIGURATION SWITCH SETTINGS
The UDC-ME is factory configured as follows:
1) Clock Source - Internal
2) Control Signals - All Signals Passed if present
3) Sync Clock Rate - 1.2k
4) Chassis to Signal GND - Not Connected
If your system application requires one or more of the default settings to be changed, this is accomplished by removing the top cover to change Dip Switches SW2-SW5 or to connect chassis to signal ground.
3.5 DATA PORT CONNECTIONS
Before applying AC Power to the unit, the users cabling to the UDC-ME Data Interfaces should be connected. Straight through shielded cables should be used. PORT A must
always have a DCE interface module plugged into the port and connect to a DTE device.
PORT B must always have a DTE interface module plugged into the port and connected to a DCE device.
3.6 SWITCH SETTINGS
3.6.1 DIP SWITCHES
The UDC-ME has three(3) dip switches. The switches are marked SW1, SW2 and SW5.
Switch SW1 allows the user to set the Clock Rate(s). Switches SW2 and SW5 allow the user to Invert the Clock and force control Signals.
3.7 EXTERNAL CLOCK OPTION
The UDC-ME allows external timing(if applicable) for applications requiring such via SW2 for either Port A or Port B.
