configurations.
Configuration:
RS-232 (DCE)
MIL 188 (DTE)
LED Indicator
Definition
Function
TD
Transmit Data
Indicates that data is flowing from RS-232
to MIL 188C.
RD
Receive Data
Indicates that data is flowing from
MIL 188C to RS-232.
RTS
Request to Send
Indicates RTS is being received from
RS-232.
CTS
Clear to Send
Indicates that CTS is being received from
MIL 188C.
*ST
Send Timing
Indicates that Transmit Clock is being
outputted to the RS-232 device.
*RT
Receive Timing
Indicates that Receive Clock is being
outputted to the RS-232 device.
*Applies to the synchronous model of the interface converter only.
