3. If a successful sign-on message is not returned, check connections and
communications factors and correct any errors.
To check connections and communications factors
1. Confirm that the Encompass 4
Reader has power.
2. Verify the connections between the PC
and the Encompass 4 Reader.
3. Verify the receive (Rx) and transmit (Tx) connections.
4. If using handshaking, verify the RTS and CTS connections.
5. Verify the COM port settings for the Encompass 4 Reader using the
instructions
in “Serial Port Communications” on page 8-18.
Repeat the procedures in “Verifying Communications” on page 8-8.
If you still cannot verify the Encompass 4 R

the capability to read tags.
