• Description: COMPUTER SNGLBD BL2500 512K FLSH
• Manufacturer: Rabbit Semiconductor

Specifications of 101-0599

• Module/board Type: Single Board Computer Module
• For Use With/related Products: BL2500
• Lead Free Status / RoHS Status: Contains lead / RoHS non-compliant

The Coyote comes with a 220  termination resistor and two 681  bias resistors installed
and enabled.
The load these bias and termination resistors present to the RS-485 transceiver limits the
number of Coyotes in a multidrop network to one master and nine slaves, unless the bias
and termination resistors are removed. When using more than 10 Coyotes in a multidrop
network, or when you need the full common-mode immunity per the RS-485 specification,
leave the 681  bias resistors in place on the master Coyote, and leave the 220  termina-
tion resistors in place on the Coyote at each end of the network.
