RS232 Serial Cable
The RS232 serial cable is used to connect the RS232 interface of M300 with the PC or data terminal
equipment (DTE) for serial communication.
The connecting procedures are as follows.
1. Convert the [RS-232/Alarms/Ext Trig] interface at the rear panel to two 9-pin interfaces using
the mixed-interface separator line (standard accessory). Wherein, one interface is a 9-pin male
interface used as a standard RS232 interface and the other is a 9-pin female interface used for alarm
output and external trigger signal input.
2. Connect the RS232 interface with the PC or data terminal equipment (DTE) using a RS232 serial
cable. Set the interface parameters (such as the baud rate and check bit) to match the PC or data
terminal equipment. At this point, you can control the instrument remotely. The measurement results
of the instrument can be output to a serial receiving device via this interface.
