East Coast Datacom, Inc. SME-530 OPERATIONS MANUAL
CHAPTER 1 - INTRODUCTION
1.1 FUNCTIONAL DESCRIPTION
The SME-530 allows two RS-530 DTE devices to communicate within proximity of each other. The SME-530 transmits data bi-directionally at data rates up to 2.048Mbps between
DTE devices. All clocking and signal crossover are provided within the SME-530. The unit is equiped with two female DB-25-P connectors.
The SME-530 is an excellent choice for interconnecting your LAN or mainframe equipment.
Substantial cost savings are derived by eliminating the need for Modems or Line Drivers.
Installation is fast and simple by setting the internal switches for Clocking and RTS to CTS delay. The SME-530 has status LED's for each attached DTE device which allows the user to visually confirm the presence of control signals.
The SME-530 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 user Baud Rates. This design approach has also eliminated clock jitter for high speed 2.048Mbps transmissions.
The SME-530 is housed in a sturdy metal enclosure and operates on 110/220VAC.
Typical MTBF figures are in excess of 100,000 hours of operation.

CHAPTER 2 - BASIC OPERATION
2.1 FRONT PANEL INDICATORS
A Green LED marked PWR illuminates when AC Power has been applied. Two adjacent sets of Green LEDs illuminate in union with individual DTE port control signal activity.
2.2 REAR PANEL CONNECTORS AND FUSES
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, Part # 714000. For 220 VAC +/- 10% operation the unit is equipped with slow blow 80ma Fuses, Part # 714001. Additionally,
DB-25 female connectors, marked PORT A and PORT B.
2.3 CLOCKING
The SME-530 provides an internal baud rate generator with user defined clock rates from
19.2Kbps up to 2.048Kbps.
2.4 ELECTRICAL INTERFACE
The SME-530 is EIA RS-530-C compliant utilizing the international EIA specification. The unit is equiped with female DB-25-P connectors. Refer to the interface chart in the
Appendix for detailed interface information.
2.5 CLEAR TO SEND (CTS) FOLLOWS REQUEST TO SEND (RTS)
The SME-530 has individual settings for each user port so that CTS follows RTS.
2.5.1 REQUEST TO SEND (RTS) DELAY
The SME-530 has individual user port settings for RTS delay. Options of no delay, 6ms,
12ms and 24ms are provided.

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 calling the fuse manufacturer: Little Fuse at (312)
824-3024 or Shurter, Inc. at (707) 778-6311
Little Fuse Part #'s are: 160ma = 218.160 and 80ma = 218.080
Shurter, Inc. Part #'s are: 160ma = 034.3109 and 80ma = 034.3106
3.3 POWER CONNECTION
Before connecting the SME-530 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 source MUST be grounded or the units Warranty will be void.

3.4 DEFAULT CONFIGURATION SWITCH SETTINGS
Page 3
East Coast Datacom, Inc. SME-530 OPERATIONS MANUAL
The SME-530 is configured prior to shipping with the Dip Switches set as follows:
1) Clock Rate - 19.2kbps
2) Port A / Port B RTS - Follows CTS
3) Port A / Port B CTS delay - No Delay
4) Chassis to Signal GND - Not Connected
If your system application requires one or more of the default setting to be changed, it will be necessary to remove the top cover. Disconnect the AC Power source before servicing the unit. Removal of the top cover is accomplished by using a small Philips screwdriver and removing the four outside screws. After setting the switches, replace the top cover before applying AC power.
3.5 TERMINAL (DTE) CONNECTION
Before applying AC Power to the unit, the DCE and DTE cabling should be connected.
Straight through Male to Male DB-25 shielded cables, no longer than 50 feet in any direction should be used. If your cables are not shielded or over 50 feet long, transmission errors may occur.
3.6 INTERNAL SWITCH SETTINGS
3.6.1 DIP SWITCHES
The SME-530 has two Dip Switch's that are accessible by removing the Top Cover.
Located safely inside the unit, you will find a 4 position Dip Switch marked S1 and a 10
position Dip Switch marked S2. To change the settings, you may use your finger tip or a small nonconductive instrument. It is recommended NOT to use metal objects to push on the Dip Switches, as you may slip and damage a component trace.
3.6.2 SWITCH FUNCTIONS
The following two pages provide a chart for the SME-530 switches and the function of each switch. Please refer to this chart for all settings.
