OP-5ML

Overview

A connection probe for monitoring TTL-level communication lines. The input level supports serial communication of IC signal level at 1.8V, 3.3V, and 5V when monitoring. Furthermore, it is possible to eject voltage for external pull-up. It is the most suitable to evaluate serial communications etc. between LSI on the print board by directly connecting with the test clip.

Applicable analyzers: LE-200PR / LE-150PR / LE-200PS / LE-150PS / LE-150P / LE-150L

Signal level can be switched by the DIP switch

You can easily switch the signal level according to the measurement target.

No.	Function	OFF	ON
1	Polarity	High level is defined as idle (no signal) state	Low level is defined as idle (no signal) state
2	Signal level	-	5V level
3		-	3.3V level
4		-	1.8V level

Supports clock signals for synchronous communication

You can input the clock for TTL level synchronous communication to the analyzers that support synchronous communication such as LE-200PR.

Lead color	Signal name	Definition/Meaning
Black	GND	Signal ground
Brown	SD	Monitor input of sending data
Red	RD	Monitor input of received data
Orange	RTS	Monitor input of control line RTS (RS)
Yellow	CTS	Input of control line CTS (CS)
Green	TXC	Monitor input for transmit data synchronization clock^*1
Blue	DTR	Input of control line DTR (ER)
Purple	DCD	Input of control line DCD (CD)
Gray	RXC	Monitor input of receive data synchronization clock^*1
Black	GND	Signal ground
White	PW	Pull-up voltage output for testing^*2

^*1: Only for the LE-200P series that supports synchronous communication (SYNC/BSC, HDLC/SDLC/X.25).

^*2: The voltage level selected by dip switch No. 2 to 4 is output with an impedance of 1.5KΩ. By connecting this PW to each input probe, it can also be used for loop testing of each signal line.

An easy-to-use IC clip (mini grabber) is attached

We adapt a high-class mini grabber that can be firmly connected.
