2. Plug one end of the null modem serial cable into the CONTROL port on the enclosure (FIG. 9).
3.
Plug the other end of the serial cable into the serial port on the serial controller/device.
4. Open the serial communication software and set the port settings to
match the Precis HT settings (see table to the right).
The settings on the PC serial communication software and the
enclosure
must correspond to each other. If a change is required to
make them match, the PC’s settings must be changed.
Caution: To avoid system damage, follow the power-up sequence on
page 26. We recommend attaching all power cords to a surge protector
and/or AC line conditioner.
5.
If not already on, apply power first to the Precis HT enclosure and then to the source and destination
devices (see “Applying Power & Startup” on page 26).
6.
Set up and run the desired method of control:
AMX Control Device – See the specific control device documentation.
APControl 3.0 – Install and open the program from the AMX AutoPatch CD. (If your AMX
account has the required permissions, the program can be downloaded from www.amx.com .)
From the APControl Launchbar menu, select System / New; select Heritage System / Next;
select Manual Configuration Entry / Next; enter VMs and number of inputs and outputs; click
Add VM / Next; finish Wizard instructions.
Terminal emulation (HyperTerminal) – Open the program (e.g., HyperTerminal), select the
COM port, and check that the settings match those in the Precis HT CONTROL Port Settings
table (see above).
Click OK.
A short splash screen appears.
7.
Execute a test switch to ensure the Precis HT is working properly (see “Executing a Test Switch,” on
page 28).
