CHAPTER 5: LED Indicator

5. LED Indicator

The front of A/S-4 enclosure provides 10 light emitting diodes (LED) indicators. The indicators are arranged and labeled in the following order, from left to right.

	TTX	Terminal Transmit Data
	TRX	Terminal Receive Data
	TCD	Terminal Carrier Detect
	TCTS	Terminal Clear To Send
	ERROR	Error Condition
	POWER	Power On
	MCTS	Modem Clear to Send
	MCD	Modem Carrier Detect
	MRX	Modem Receive Data
	MTX	Modem Transmit Data
TTX	Flashes as data is transmitted by the A/S-4 out the terminal port.
TRX	Flashes as data is received by the A/S-4 from the terminal port.
TCD	Lights when the A/S-4’s input of Carrier Detect is high on the terminal port. This light
	must be on while TRX is flashing for A/S-4 to process received data.
TCTS	Lights when the A/S-4’s input of Clear to Send is high on the terminal port. This light
	must be on for the A/S-4 to transmit data on the terminal port.
ERROR	Error Condition Exists - Memory error, bad received block check, or buffer overflow.
POWER	Lights when the A/S-4 is plugged in and the +5 Volt power supply is ok.
MCTS	Lights when the A/S-4’s input of Clear to Send is high on the modem port. This light
	must be on for the A/S-4 to transmit data on the modem port.
MCD	Lights when the A/S-4’s input of Carrier Detect is high on the modem port. This light
	must be on while the MRX is flashing for the A/S-4 to process received data
MRX	Flashes as data is received by the A/S-4 from the modem port.
MTX	Flashes as data is transmitted by the A/S-4 out the modem port.
