2.2.Setup

Objective of Setup

In normal condition, it is not necessary to setup the OMR-6520. The default configuration of this communication module is 9600 bps and data format of 8 data bits with 1 start bit, 1 stop bit, and no parity check. Note that the data format is reserved to be compatible with other brand‘s communication port; it should not be modified if only OMR is used in a system. The baud rate can be configured according applications’ requirement.

Setup Equipments

Only screwdriver is used to open the case. Software, power supply, and wiring are not necessary.

Setup Procedure

Only hardware switch setting can be setup in OMR-6520. The user can set the speed of the serial interface (RS-232 and RS-422/RS-485), and the serial data format. The speed and the data format on the whole RS-485 network must be identity otherwise the communication will be not correct.

To setup the OMR-6520, use the screwdriver to open the case, then change the switch setting. The new setting is available after power on. The case must be put back and locked carefully. Note that do not scratch the surface of the circuit while setting up, otherwise the surface coating or even the circuits will be damaged.
