LTC100 RS485/RS422 to Serial Converter |
|
|
|
For serial converters that convert serial
signals and extend communication range, SENA provides the
product of converting RS232 signals into RS422 or RS485
signals.

|
The LTC100 serial converter is designed for
long-range communication. The transmit distance extends up to 1.2
KM (0.74 miles) at speeds up to 921.6Kbps. Multi-drop function
enables to connect 10 devices in RS422 mode, and bus scheme
enables to connect 32 devices in RS485 mode. Further, the new
comer is fully compatible with serial COM port in PC.
The LTC100 serial converter is also equipped with 15 KV ESD
Built-in surge protection to safeguard the device from
electrostatic discharge, which could interrupt the system
operation. Features:
● Max. distance 1.2 km
● Fully compatible with PC serial COM ports
● No external power supply required
(port-powered)
● Optional external DC power supply (9VDC)
● Built-in surge protector up to 15kV
● RTS auto toggling
● Communication status can be monitored using
LEDs
● DIP switch for RS422/485 mode selection
● Max. 10 device connectivity for RS422
multi-drop mode
● Max. 32 device connectivity for RS485 mode
