OHSP-350 series external interface description
1、 This description is only valid for OHSP-250X/350X series devices with external interfaces. This interface is added on the
basis of the original OHSP series equipment. The equipment with external interface can have the following functions:
2、 1. External input trigger function; that is, the remote test function can be realized through the external interface.
3、 2. 485 communication function; this external interface supports ultra-long-distance RS485 half-duplex communication.
4、 3. Switch signal output function; this interface can provide two switch signal output.
5、 4. External power supply; this interface can directly supply power to the device, which is convenient for devices without batteries.
Note 1: Mode 1 and Mode 2 can be set on the device. The specific operation is to enter Settings -> Measurement Settings ->
Input and Output Settings and select Mode 1 or Mode 2.
Note 2: The 120R terminal matching resistance is not connected inside the RS485 interface.
