Introduction:
model277 is one kind can offer rs-232485422 serial port carry transparent optical fiber modem of transmission to get end to user, no need patch cords set up, switch over automatically, and can detect and examine the signal speed automatically, zero delays time to transmit automatically. model277 adopt optic fiber transmit, have isolate protection, data privacy is fine, working steady, data, such threats to communication equipment as the wave is welled up and interfered with electromagnetically that the effective one has prevented the abominable environment from being struck by lightning, can work in the abominable and dangerous environment reliably.
Can be used in occasions such as various industrial control, course controlling, traffic controlling and intellectual district , especially suit the bank, electricity and interfering with environment department and system with the special requirement electromagnetically.
Features:
1. Extend rs-232485422 transmission up to 120km with single-mode
2. Transmit asynchronously, point to point, speed reach 500kbps
3. Examine signal speed automatically, zero delay time
4. Plug-and-play(hot-pluggable, data format auto-sensing & self-adjusting)
5. Support rs-232485422 interface type, but only one rs-232 rs-485 rs-422 port can be connected at a given time
6. 9~36vdc power supply input(2 bit terminal block)
specifications:
rs-232485422
standards: eia rs-232c, rs-485, rs422 standard
rs-232 signal: out(tx), in(rx), gnd
rs-422 signal: t+, t-, r+, r-, gnd
