HPM-2002-OBE RS232/485 Output Module, Specifications

1.5. HPM-2002-OBE RS232/485 Output Module

The RS232/485 module consists of a power conversion/sensor transducer board, microprocessor board and a user interface option board. Serial communication is conducted via an RJ-11 type connector. With RS232 option (EIA-232 Rev. E) communication can easily be established between the module and the serial port of a PC. The RS485 option allows the user to address multiple units and allows operation at distances of up to 4000 feet. The RS232/485 module includes a four digit floating-point LED display.

1.6. HPM-2002-OBE DeviceNet Module

The DeviceNet module consists of a power conversion/sensor transducer board, microprocessor board and a user interface option board. All communication is conducted via a 5-pin “Micro” style with center pin, male pin contacts. The module has passed the ODVA DeviceNet test and conforms to the vacuum/pressure gauge device profile, an Electronic Data Sheet (EDS) with limited features is also available upon request.
