X-Y Control
of Another
X-Y P12×1-SP:
LXYTOXY
Use the LXYTOXY to allow remote control of a Harris router using Harris X-Y
control panels. In this application, the P12×1-SP translates from X-Y protocol to
the RS-232 required by the modem and then translates from RS-232 back to X-Y
on the remote site. Using another LXYTOXY on the remote site allows the modem
connection to filter out the “random characters/noise.” The LXYTOXY does not
communicate with the modem, it expects the modem connection to look like a
“wired” connection. Therefore, the LXYTOXY should not be used when a dial-up
connection is required, unless the modem pairs hide this function from the
LXYTOXY.
The LXYTOXY supports all functionality of pass-through protocol.
