I am using another Manufacturers RS232 to RS485 converter and I cannot get it to communicate with the Nexus® meter. What is the problem? .
Before we answer this question, let me explain about the two types of converters that are typically used. The first is your basic interface only converter, and the second is a converter that supports Send Data Control. What determines the type of converter that is used is the software that is being used with the converter and the cost.Basic Converters The basic interface only converter needs RTS Control. RTS Control is relevant only if you are converting to 2-wire RS485 (where the converter is a Master or a Slave) or to 4-wire RS485 (where the converter is a Slave). RTS Control is a method with which the RS232 device (typically a PC) tells an RS232-RS485 converter when it should enable its RS485 driver, i.e. when it should be transmitting. On a converter, which is an interface converter only and does not monitor the data, an external signal is required. When providing RTS Control, the RS232 device raises its RTS output immediately before it starts to communicate, and drops it after the
