Communicating data

After the MRC-921 has been connected to the host

and properly configured, communication usually

follows this general pattern:

1.All three units (PTC-921, MRC-921, and host) are

turned on.

The default message is usually an

asterisk (*).

The PTC-921 initiates communication with the

MRC-921. After a successful logon, a default

message displays on the PTC’s screen.

3.Data is entered (either by being scanned or typed

with the keyboard) into the PTC-921.

The data usually includes the PTC

unit ID, the data-entry type (scanned

or keyed), and the bar-code type.

The data is sent via the PTC-921’s MicroRadio to

the MRC-921.

5.The MRC-921 forwards the data to the host.

Refer to the

MRC-921 Technical

Reference

for a list of messages that

may display on the PTC’s screen.

If the data is received successfully, an asterisk

displays on the PTC-921’s screen.

If the data is not received successfully, an RF link

error displays on the PTC-921’s screen.

Communication continues with the PTC-921

sending data to the host through the MRC-921.
