Description

The TTL-530 Interface Converter 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.
