Function
The Termination Resistor for RS485_2 is IN.
The Termination Resistor for RS485_2 is OUT.
Jumper J18
The J18 jumper connection controls the selection of the RS485 termina-
tion resistor circuit. When the shunt is placed, the RS485 termination
resistor circuit is enabled. See Table 22.
A number of connectors are available for connecting external devices
such as the ZPAKII emulator, PC serial ports, external modems, the con-
sole, and LAN/telephone lines.
J6 and J8 are the headers, or connectors, that provide pin-outs to connect
any external application module, such as ZiLOG’s Thermostat Applica-
tion Module.
Connector J6
The J6 connector provides pin-outs to make use of GPIO functionality.
Connector J8
The J8 connector provides pin-outs to access memory and other control
signals.
