Frequently Asked Questions
What is the general wiring procedure for RS-232 connection using XGL-CH2A?
Use a 9 pin D-sub connectors. RXD connects to TXD, and TXD connects to RXD, while GND (pin 5) must be linked.
How are RS-422 signal pins mapped for DOP-A/AE series?
It uses a 9 pin D-sub male connection where TX+ links to RX+, RXD+ links to TX+, and the corresponding minus rails are connected via specified pins.
What is the addressing range for Data Registers (DWn)?
Data registers (DWn) have a read/write address range from DW0 to DW32767, using Word length data type.
What connection mechanism must be used for DOP-AS35/AS38/AS57 series with RS-422?
The connection requires a Terminal Block setup. TX- connects to R-, and RX+ connects to T+, while GND is wired via pin 5.
