Patton electronic 1060 AC Powered Multipoint Configuration, 3.2 DCE/DTE SWITCH SETTINGS

3.1.2 MULTIPOINT CONFIGURATION

The Model 1060 supports multipoint operation in either daisy chain or star configurations. For multipoint configuration and wiring information, refer to Section 4.2, pages 7.

3.2 DCE/DTE SWITCH SETTINGS

Correct setting of the DCE/DTE switches eliminates the need for RS-232 crossover cables. If the RS-232 device you are connecting to the Model 1060 is a PC, terminal or host, or is wired like one, set both of the DCE/DTE switches to "DCE". If the RS-232 device you are connecting to the Model 1060 is a modem or multiplexer, or is wired like one, set both of the DCE/DTE switches to "DTE".

3.3 SPECIAL CONFIGURATION

If your installation requires special configuration of the Model 1060, use Table 1 (below) as a guide. This table shows all of the possible Model 1060 switch settings. Following the table are brief descriptions of the Control Input, Control Output, +Voltage Output and Carrier Controlled by (Cin) parameters shown in the table below.

*Multiple input pins are "or-tied"—if any input goes low, carrier is dropped

**Multiple output pins generate the same signal simultaneously

Table 1. All possible switch settings for the Model 1060

Control Input (Cin):

The Control Input signal is used by the local Model 1060 as an input signal to activate its transmitter (“Enabled” settings) and allow data transmission to the remote device. This is required for half-duplex/ switched-carrier environments as well as in hardware flow control applications. In the “Disabled” settings, the 1060 is always “turned on” and sends a continuous carrier to the remote 1060.

Control Output (Cout):

The Control Output signal is transmitted by the local Model 1060 to its attached DTE device. This signal should be the same logic state as the Control Input signal on the remote 1060. This signal is required in half-duplex/switched carrier environments or in hardware flow control applications.

+Voltage Output (+Vout):

The +Voltage Output signal is a constant positive voltage that is

sent from the 1060 to its attached DTE device.

Carrier Controlled by (Cin):

When Carrier Controlled by Control Input is “Enabled”, the Model 1060’s transmitter is activated by the corresponding Cin Signal from the DTE. In effect, the Control Input signal on the local 1060 "controls" the presence of "carrier" and the Control Output signal on the remote 1060. This setting is required in half-duplex/switched carrier environments or in hardware flow control applications. When Carrier Control by Control Input is “Disabled”, the 1060 sends a continuous carrier and is always “turned on”.
