Problem Causes
Data LED and Bus LED
intermittently blink
• Firmware does not match
The firmware for all base modules must match and the firmware for
all expansion modules must match. The firmware rev number may
be viewed on the information tab of the configuration software.
If the firmware does not match, then update the firmware with the Firmware
Updater Program.
• No Peer-Peer communication link
The serial connection is not established. Verify that all parameters in
the configuration tab in the programming software are correct.
• Too many expansion modules installed
Only 6 expansion modules may be connected to any base module.
• Expansion modules in peer-peer mode do not match
In peer-peer mode, the master and slave must have the same number of
expansion modules.
• Expansion module added/removed without cycling power on base
module
The Zlinx 485 configures the base module and expansion modules on a cycle
of power. No damage occurs by adding/removing a module “hot.” Power will
need to be cycled for the base module to update the expansion locations.
