RS232 to RS485 auto enabled converter din rail mounting
FEATURES:
DTE/DCE selectable,no null modems needed.
Auto enabled no drivers required no dip switches.
Status LEDs for PWR TX and RX lets you see whats happening.
-40°C to +85°C industrial temperature range standard
Built in active termination jumper selectable.
Microprocessor controlled.
PROGRAMMABLE Feature allows communication with devices with
a fast response time.
Two automatic RS-485 transmit enable modes:
Bit time calculated
Transmit turnaround is automatically controlled by calculating one byte idle time of the current baud rate.
Fixed baud rate
Transmit turnaround is automatically controlled to near zero turnaround time for a set of fixed baud rates ranging from 1200 to 115,200 baud.
See the Users Manual pages 6 and 7 for more details.
