RS-530 Expansion Kit
(For LE-3500XR/2500XR



OP-SB10N is a measurement board which has a RS-232C (V.24) interface of DSUB 25-pin and a RS-422/485 (RS-530) interface of DSUB 25-pin. By using dedicated cables, you can easily connect to legacy ports such as RS-449, X.20/21, and V.35 for measurement.

Applicable analyzers: LE-3500XR/LE-2500XR/LE-3500R/LE-2500R/LE-1500R

* LE-8200A/LE-8200/LE-3500/LE-2500/LE-1500 has a RS-530 port as standard.
Supports control lines of RS-422

The standard measurement port for LE-3500R/LE-2500R/LE-1500R and the LE-3500XR/LE-2500XR is a terminal block of RS-422/485 interface, 5 poles (transmit/receive signal and signal ground only). And it has no RS-422 control line. As the RS-422/485 interface of OP-SB10N has control lines RTS/CTS and DSR/DTR, the analyzer can monitor and simulate using these lines.

< Terminal Block for DSUB 25-Pin LE-25TB (Option) >

Converts analyzer's RS-422/485 port (DSUB 25pin specifications) to terminal block specifications

Also for maintenance of legacy switchboards

Optional cables for interfaces such as RS-449 (multiple RS-422 differential signals are arranged), X.20/21, and V.35 (RS-232C level signals are combined and arranged) ares available. By connecting these dedicated cables to RS-530 ports of OP-SB10N inserted to LE-3500XR/LE-2500XR, maintenance and trouble analysis of legacy switchboards etc. can be possible.
