Panel Bus Connection
The CIPer Model 50 controller features two RS485 interfaces to which Panel Bus modules can be connected:
RS485-1 (consisting of push-in terminals 24 [GND-1], 25, and 26) and/or RS485-2 (consisting of push-in
terminals 29, 30, and 31 [GND-2]).
NOTE
GND-2 is internally connected with 24V-0 (terminal 1)

Panel Bus Considerations
•
RS485-1 (isolated)
–
Max. Panel Bus length:
o
1200 feet. Any type of cabling and topology (including star and loop topology) possible. No
additional end termination permitted.
o
3600 feet (9.6
–
78.8 kbps) or 2400 feet (115.2 kbps) (see also section "RS485 Standard").
Mandatory twisted-pair or telephone cable and daisy chain topology. The CIPer Model 50
must be positioned at one end of the Panel Bus, and an end termination (120
Ω
) at the other
end. Further, the three-position slide switch (see Figure 14) must be set to "END."
•
RS485-2 (non-isolated)
–
Max. Panel Bus length:
o
1200 feet. Any type of cabling and topology (including star and loop topology) possible. No
additional end termination permitted.
o
3600 feet (9.6

78.8 kbps) or 2400 feet (115.2 kbps) (see also section "RS485 Standard").
Mandatory twisted-pair or telephone cable and daisy chain topology. The CIPer Model 50
controller must be positioned at one end of the Panel Bus, and an end termination (120
Ω
) at
the other end.
