GENERAL INFORMATION

1.1 INTRODUCTION

This manual contains descriptions, setup and operating

instructions, specifications, maintenance, and service infor-
mation for the TTC (Telecommunications Techniques Cor-
poration) Model 41400 RS-449/530/MIL Data Interface.
The RS-449/530/MIL Data Interface allows the FIREBERD
4000 (Rev 3 and above) and FIREBERD 6000 (Revision G
software and above) to be connected to RS-449, MIL-188-
114, EIA-530, MIL-188C and compatible circuits and to act
as a DTE or DCE device in balanced or unbalanced mode.

1.2 SAFETY CONSIDERATIONS

The following safety considerations should be observed:

•

Use a grounding strap when removing or installing
this interface.

•

Ensure that power is off when removing or installing
this interface.

•

Remove or install the RS-449/530/MIL Data Inter-
face, Model 41400, in a moisture free environment.

•

Make sure the RS-449/530/MIL Data Interface, Model
41400, is used with well grounded equipment.

•

Always wear safety equipment appropriate for the
job, such as eye protection.

•

Never operate the equipment when combustible gases
or fluids are present.

1.3 ENVIRONMENTAL CONSIDERATIONS

The RS-449/530/MIL Data Interface, Model 41400,

should be operated in a non-combustible atmosphere. There
should be no flammable materials in the area. This RS-449/

530/MIL Data Interface, Model 41400, and associated equip-
ment, is sensitive to corrosive materials, including exposure to
salt. This unit is not waterproof.

1.4 INTERFACE FEATURES

The RS-449/530/MIL Data Interface has the following

features.

•

Compatible with RS-449, MIL-188-114, EIA-530,
and MIL-188C standards.

•

Emulate DTE or DCE.

•

Circuit connections using either the 25-pin D-type,
37-pin D-type, or twinax connectors.

•

Operates in balanced or unbalanced interface mode.

•

User selectable terminating impedance.

•

Test in synchronous timing up to 15 Mb/s.

•

Test in asynchronous timing up to 20 kb/s.

•

Test in recovered timing up to 520 kb/s. (FIREBERD
6000 with clock recovery option.)

•

Controlled through the FIREBERD front panel Inter-
face Setup menu or by remote control.

•

Control RL and LL lines while emulating DTE and TM
and CTS lines while emulating DCE.

•

Select ground termination technique on receive clock
and receive data lines.

•

Set the polarity of all interface signaling control leads.
