RS-232 Connection (Modem Use)

Modem controls, discussed in Section 5, User Interface Guide, enable or disable modem control through the RS-232 interface. When this option is enabled from a standard terminal connection, all RS-232 communications cease until a modem with a null modem adapter is attached between the TRACER 4106/4206 and the data modem. Configure the data modem for AUTO ANSWER and 9600 BPS. When the user connects via the modem to the TRACER 4106/4206 unit, communications via the RS-232 port resume. If a user accidentally enables modem control from a terminal and disrupts the RS-232 communication, pressing <Ctrl + Z> three times will temporarily disable the modem control option (until the system is reset) and will access the system option to disable modem control.

The TRACER 4106/4206 must be interfaced to a modem via an RS-232 null modem adapter or cable. The null modem converts Clear To Send (CTS) and Data Set Ready (DSR) into Ready To Send (RTS) and Data Terminal Ready (DTR), respectively. These signals indicate (to most modems) that a valid DTE terminal device is present. The null modem interface must route Carrier Detect (CD) on pin 8 directly from the modem. When using the RS-232 interface for modem control, the modem must source CD only when actually connected to a carrier.

When MODEM CONNECTION is selected in the menu system, the TRACER 4106/4206 will de-assert DTR and DSR for a time greater than 20 msec. The null modem consequently drops DTR and RTS at the modem interface, signaling the modem to hang up the line. If password functionality is enabled in the TRACER 4106/4206, selecting MODEM CONNECTION resets the TRACER 4106/4206 to the password entry
