MAX13485EEVKIT+
MAX13485E EV kit
5V DC power supply
Two digital voltmeters
Verify that the jumpers are in their default position,
as shown in Table 1. JU1 connects the 120Ω load
resistor between A and B.
For testing purposes, remove the shunt from JU1.
Connect the positive terminal of the 5V supply to
VCC and the negative terminal of the supply to GND.
Apply 5V on the RE and DE pads. This is a logic to
RS-485 DC test.
Apply 5V on the DI pad and check that A-B is posi-
tive.
Apply 0V on the DI pad and check that B-A is posi-
tive.
Apply 0V on RE and DE. Apply 5V on A and 0V on B.
This is an RS-485 to logic DC test.
Check the state of RO using a voltmeter. RO should
be approximately 5V.
