Integer, Index and Logic has always scale factor 1. EXOline/ The STRA controller automatically switches between EXOline and depending on the present communication type, without any communication error. wiring etc. A protocol such as consists of several layers (OSI-model). The bottom layer is always the physical layer, of wires and signal levels. The next layer describes the communication digits ( of data bits, stop-bits, parity etc). Then come the layers describing the specific functions ( of digits per message, the meaning of different messages etc). For, the bottom layer can be RS485, RS422 or RS232. RS485 & RS42 RS485 and RS422 are the electric part of the protocol, i. e. the physical layer. RS485 has two connections, A and B. Often there is also a protective earth (N on EXO controllers). RS485 units are connected A to A and B to B. You may have to shift A and B in order for to work. RS485 is so called half duplex communication: Communication can only go in one direction at a time; i. e. the master will first send an enquiry and will thereafter listen for the reply. A and B are used for both transmission and reception. RS422 is a full duplex communication which means you need 4 wires, 2 for transmit (Tx+ and Tx-) and 2 for receive (Rx+ and Rx-). Tx is used to transmit and Rx to receive, which means that Tx in one unit must be connected to Rx in the other and vice versa. As for signal levels etc. RS422 and RS485 are identical. To interconnect RS485 and RS422: On the RS422 unit connect Tx+ with Rx+ and Tx- with Rx-. We have now changed a 4- wire system to a 2-wire system and can connect them to A and B on the RS485 unit. Which goes where is something you most often need to find out by trial and error. Incorrect polarity will just give nonfunction but cannot harm either unit. Tx+ ----- ---------------------------------------- A (or B) Rx+ ----- Tx- ----- ---------------------------------------- B (or A) Rx- ----- Bitrate, two stop bits, parity is the next layer. These settings must correspond to the settings in the master unit. Find out how the master is set and then give the Controller the same settings. Parity can be set to odd, even (FS) or none. If none is chosen, two stopbits will automatically be used. If odd or even is chosen only one stop-bit is used otherwise there will be too many bits altogether: 1 start-bit, 8 data-bits, 1 parity-bit and 1 stop-bit give a total of 11 bits which is maximum. 1 (10) Specifications are subject of alteration without further notice.

Connect pin 42 to the RS485 (DATA - / A) bus connector. Connect pin 43 to the RS485 + (DATA+ / B) bus connector. NOTE: Use appropriate bus termination and bias resistors. The RS485 standard allows for the connection of 32 devices on the bus with a maximum cable length of 1200 meters for the lower baud rates. 3 (10) Specifications are subject of alteration without further notice.
