RF SCALE INSTRUMENTATION
rent flow. RS422/485 connections require a termination resistor to reduce reflections. See wiring diagrams for
details.
Both RS-422 and RS-485 are multi-drop capable. The CellScale can drive up to 32 receivers on one twisted
pair. Although the CellScale uses standard RS-485 drivers, the standard software does not have a full duplex
protocol. Contact MSI for custom solutions for networking with RS-485.
Comm Port Cable Color Code RS-422/485
Brown – TD+ (Y)
White – TD- (Z)
Black – RD+ (A)

Blue – Signal Ground
Drain Wire – Connect to metal shell.
If the CellScale is the final device in a chain, connect a 1/4W 120Ω resistor from RD+ to RD-. Terminating T
connectors are available, contact MSI for details.

SERVICING THE 6260CS
MSI’s Dealer Network provides both on-site and depot servicing of 6260CS Crane Scales. Please contact your
local dealer. MSI also operates a service center for all our products. Contact MSI Service at 1-206-433-0199
to obtain an RMA (returned material authorization). Due to the weight and size of many of our products, it is
not always necessary to return the whole scale. If the electronics are at fault, you can often return just the front
casting section. See the following illustration. MSI cannot guarantee that calibration will be restored if you
choose to return just the electronics. If you are able to perform an on-site calibration, then this might not be a
consideration. Always inspect the load train for stress and fatigue wear before returning the scale to use.
There are no user servicable parts inside the 6260CS. Depot repair is performed with module and harness
swaps.
