7 Module Configuration
7.1 Cable Connections
The application ports on the PTQ-AFC module support RS-232, RS-422, and
RS-485 interfaces. Please inspect the module to ensure that the jumpers are set
correctly to correspond with the type of interface you are using.
Note: When using RS-232 with radio modem applications, some radios or modems require
hardware handshaking (control and monitoring of modem signal lines). Enable this in the
configuration of the module by setting the UseCTS parameter to 1.
7.1.1 RS-232 Configuration/Debug Port
This port is physically a DB-9 connection. This port permits a PC based terminal
emulation program to view configuration and status data in the module and to
control the module. The cable for communications on this port is shown in the
following diagram:
The Ethernet port on this module (if present) is inactive.
7.1.2 RS-232 Application Port(s)
When the RS-232 interface is selected, the use of hardware handshaking
(control and monitoring of modem signal lines) is user definable. If no hardware
handshaking will be used, here are the cable pinouts to connect to the port.
