X-Y Control
of a Remote
Router via
Modem:
LXYTOMO-
DEM
Use the LXYTOMODEM configuration to allow remote control a of 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. The P12×1-SP does not
communicate with the modem; it expects the modem connection to look like a
“wired” connection. Therefore, the LXYTOMODEM configuration should not be
used when a dial-up connection is required, unless the modem pairs hide this
function from the P12×1-SP.
NOTE : See the Serial Protocol Reference for more information about
pass-through protocol.
The LXYTOMODEM supports all functionality of pass-through protocol. The
features supported are as follows:
