ENAMEL RATER MANUAL: V.10

The jumpers on the micro board must be changed according to the

communications standard used:

RS232

RS422

RS485

SW11/4 on the applications board selects between RS422 and

RS485. When SW11/4 is off RS422 is selected. If RS422 or

RS485 is to be used the plug connecting the socket on the rear

panel to the microboard should be moved from P2 to P3. These

connectors are marked on the circuit board.

7.4

UNI-DIRECTIONAL PROTOCOL

If SW11/3 on the applications board is off (open), uni-directional

protocol is used. As each reading is saved it is automatically sent

down the serial port, if the hardware handshaking line is clear.

7.5

BI-DIRECTIONAL PROTOCOL

If SW11/3 on the applications board is on (closed), bi-directional

protocol is used. As each reading is saved it is stored in an internal

buffer, which is battery backed in case of power failure. When the

enamel rater receives a data request message from the host

computer the data stored in the buffer is sent.

Data Request message:

<40h><01h>

where:

<40h> (1 byte) ASCII character '@'

<01h> (1 byte)

When using bi-directional communications, software handshaking

is available as an option as well as hardware handshaking. If

selected, (SW2/2 closed on the micro board) the XON/XOFF

protocol is used. If XOFF is sent to the enamel rater it must be

followed by XON before any further transmission will occur.
