About East Coast Datacom, Inc

East Coast Datacom, Inc. is a customer oriented, high technology enterprise which was formed in 1994 to design, manufacture and support Wide Area Network Equipment. We manufacture the broadest line of Network Emulators in the network test equipment market supporting over 18 different interfaces for Serial, Telco and Ethernet.

For Ethernet, the WanRaptor™ Network Emulator allows users to test and stage critical network equipment adding network latency, loss, Jitter and re-ordering impairments. For Serial data and Telco the RDS-PLUS delay simulator is a modular, network link error and delay emulator that provides a realistic simulation of physical network behavior with respect to time delays and bit errors.

We also manufacture an extensive line of legacy network equipment critical to the military, government and Fortune 500 companies. These include data broadcast splitters, digital sharing devices, interface converters and many other network adapters. Our highly respected Sync2IP Converter is a unique solution for Sync data to IP conversion as we support any sync data protocol.

We hope you enjoy our collection of products we present on our web site. Keep in mind we can modify or design a new solution for your unique application.

The TTL-530 is a TTL to RS530 interface converter that is designed to provide signal level conversion between TTL Clock and Data signal levels (as used in telemetry equipment) and RS-530 (V.11) DTE (Terminal) equipment.

The TTL-530 accepts TTL signal levels into the Input Ports via BNC connectors. The TTL signal levels are converted to ITU V.11 (Balanced) voltage levels and are then transmitted on the Output Port. The Output Port is a DB-25-P (Female) connector with RS-530 pin assignments. The TTL-530 is capable of data and clock transmission at rates up to 10Mbps. A second set of BNC connectors are provided for remote DTE loopback testing providing bi-directional transmission.

The TTL-530 has two separate TTL to RS-530 converters designed in the same chassis. The chassis is made of sturdy aluminum and is rackmountable at 1U (1.75 inches) high. The device is shipped with rackmount ears for standard 19 inch cabinets.

The TTL-530 operates on 115/230VAC switch selectable power. A voltage selection switch is located on the rear of the device. An IEC power connector is provided for power cord connection. A standard three pronge (grounded) continental US power cord is provided with the device.

The TTL-530 has a three year, return to factory warranty.
