Telephone
Line
Connection
The RJ11C connector on the NET-PATHm mates with standard modular cables
commonly used with telephone equipment. Connect one end of the cable to the NET-
PATHm and the other end to the wall or floor jack assigned to the telephone line. The
NET-PATHm must connect to a dedicated telephone line for reliable operation. We
recommend that you use an external, business telephone line.
Contact Sensor
Inputs
The NET-PATHm provides four contact sensors. The RJ45 jacks on the back of the
NET-PATHm accommodate four contact sensor inputs each. These jacks, labeled
“Contact Sensor Inputs,” are marked with a blue symbol. Each contact sensor input
detects and reports when the state of an attached external device changes. You can
configure each sensor as normally open or normally closed through software options
in the NET-PATHm database.
NET-PATHm contact sensors support two types of input sensing. The first type of
input sensing is based on RS232C and supports wet input. The second type is also
based on RS232C and it supports dry input.
The general operation of each sensor is the same regardless of how it was configured.
The sensor reports a change in state (inactive to active or active to inactive) when the
input voltage passes through a detection threshold and remains at the new level for a
user-defined period, usually several seconds.
7 CTS Clear to Send IN Hardware handshake

connected host is
ready to receive.
8 RTS Request to Send OUT Hardware handshake
will be on when the

Warning
When configuring the NET-PATHm with an
international modem, do not connect the modem to the
telephone network until you have programmed it with the
appropriate country code. If you are unsure of the modem
type, you can review the model structure information
displayed on the serial number label attached to the bottom
of the unit. “Determining the NET-PATHm Model” on
