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 Interface 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.
