Star Micronics TSP2000 C-2. Function for Compatibility Mode, Pin No, Signal Name, In/Out

C-2. Function for Compatibility Mode

Pin No.		Signal Name					IN/OUT	Function
1							IN	Signals when data is ready to be read. Signal goes
						STB
								from HIGH to LOW (for at least 0.5 microsec.) when
								the data is available.
2-9				DATA0-7			IN	These signals provide the information of the first to
								eighth bits of parallel data. Each signal is at HIGH level
								for a logical 1 and at a LOW level for a logical 0.
10							OUT	LOW pulse acknowledges receipt of the data.
				ACK OUT
11		BUSY OUT					OUT	When this signal goes to LOW, the printer is ready
								to accept data. When the printer is in one of the
								conditions below, “HIGH” is set.
								1. Data is being entered
								2. Off line
								3. Error condition
12				PE OUT			OUT	This signal indicates the status of the paper sensor.
13	SELECT OUT						OUT	This signal is HIGH when the printer is online.
14				AUTO IN			IN	This signals that the printer is processing a paper
								feed command from a host computer.
15						NC		Unused
16					GND			Signal ground
17						FG		Chassis ground, isolated from logic ground
									APPENDIX
18			Logic High
19-30					GND			Twisted pair return the signal to ground level.
31							IN	When this signal goes to LOW, the printer is reset to
					INT IN
								its power-on condition.
32							OUT	This signal is normally HIGH. This signal goes to
		ERROR OUT
								LOW to signal that the printer cannot print due to an
								error condition.
33					GND			External ground
34				DKSTS			OUT
35			Logic High
36							IN	Puts printer in Select mode
			SELECT IN
