To Set the RS232

Before any related operations, use RS232 cable to connect the multimeter to a PC

or data terminal equipment (DTE). Then, set the interface parameters such as

baud rate, parity and handshake to match the mutlimeter with the PC or data

terminal equipment, in order to control the multimeter. The measured result can

be transferred into serial receiving device (PC) via this interface.

Abbreviation

Function

1* PASS (Carrier Detect) Output negative pulse if P/F test

succeeds

2 RXD (Receive Data) Receive data

3 TXD (Transmit Data) Send data

4 DTR (Data Terminal Ready) Data terminal is ready for receiving.

5 GND (Signal Ground) Signal Ground

6 DSR (Data Set Ready) Data is ready.

7 RTS (Request To Send) Unused

8 CTS (Clear To Send) Unused

9* FAIL (Ring Indicator) Output negative pulse if P/F test fails

*Remark: Pins 1 and 9 always outputs high level when P/F output is disabled.

WARNING

The P/F signal from pins 1 and 9 of RS232 is not compatible with the

handshake signal (Carrier Detect and Ring Indicator) from standard

RS232.
