3.2.Setup

Objective of Setup

In normal condition, it only needs to setup the OMR-6510 when the OMR bus with more than 128 modules or the distance exceeds 4000 feet long. 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 user’s requirement.

Setup Equipments

Only screw driver 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-6510. The user can set the speed and the data format of the RS-422/RS-485 interface. The speed and the data format on the whole network must be identity otherwise the communication may be not correct.

To setup the OMR-6510, use the screw driver 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.
