Installing the VA8200 Panel Link Module
The VA8200 Panel Link Module (PLM) connects to the keypad (ECP) terminals on the VISTA-128BPEN and also
connects to other PLMs via the RS-485 bus (3-wire twisted cable run).
Figure 3-26
is a block diagram of a panel linking
setup using three control panels.
UL
Panel Linking is not permitted in UL
installations.

ECP Wire Run Limitations
Determine wire gauge by referring to the table below.

•
The
length of the ECP wire runs combined must not exceed 2000 feet when unshielded cable is used (1000 feet
if unshielded cable is run in conduit or if shielded cable is used).
•
If more than one ECP device is wired to a single run, then the above maximum lengths must be divided by the
number of devices on the run (e.g., the maximum length is 225 feet if two keypads are wired on a #22 gauge
run).
RS-485 Bus Wire Run Limitations
The RS-485 bus from the first Panel Linking Module to the last Panel Linking Module cannot exceed 4000 feet, using 16-
AWG twisted-pair cable.
The recommended form of wiring is to daisy chain the connection from one unit to another. If several buildings are to be
connected, the RS-485 bus should form a continuous path from one building to the next.
Avoid wiring units in a star configuration, where multiple branches are formed. Star configurations create loading and
capacitance problems that are complex, and become difficult to troubleshoot.
