External Relays & Digital I/O Connections
The relay and the digital I/O expansion modules PDA1004 & PDA1044 
are connected to the meter using a CAT5 cable provided with each 
module. The two RJ45 connectors on the expansion modules are iden-
tical and interchangeable; they are used to connect additional modules 
to the system. 
Note: The jumper located between the RJ45 connectors of the 
PDA1044 must be removed on the second digital I/O module in 
order for the system to recognize it as module #2. 
Warning!
Do not connect or disconnect the expansion modules with 
the power on! 
More detailed instructions are provided with each optional 
expansion module.
