8 RS232 interface
The RS232 data rate can be tuned from 1200 to 115200 b/s with parity (even / odd) or no parity.
The data terminal must be less than 10 meters far from the modem.
Cables can be provided to connect the product to DTE and DCE as follows :
RS232 cables (L=1m)
Code User connector Cable function
CAB592 SubD 9 male To connect a DCE to the XSRING+
CAB593 SubD 9 female To connect a DTE to the XSRING+
CAB609 Wires To connect a device providing a specific connector
9 RS485 interface
The RS485 serial interface is provided on the front
panel 2 pins screw-block.
Polarisation resistors
Two 10 Kohm bus polarisation resistors are included
inside the product.
Remark :
The RS485 interface of the XSRING+1220 or 2220 is made for connecting only one device at short
distance, inside the same cabinet for instance, and at low data rate up to 19200 b/s.
If the RS485 line has to be longer, one of the devices connected to the RS485 line must provide
standard polarisation resistors, and a 150 Ohm termination resistor must be connected at each end of
the line.
