No commands can be received in this mode but the front panel MENU can be
accessed. Any transmissions received other than properly formatted data will result
in a meaningless display. Alarm setpoints, Peak readings and external control
functions are disabled while the Remote Display value is being displayed. When the
DPM is Reset, it displays RESET continuously until data is received.
5.4.2. COUNTER
The Counter has 13 Display Modes (0-12). Modes 0-5 are normal measurement
modes and Modes 6-12 are dedicated to Remote Display only without making any
normal readings. In any of the 12 modes, remote display data may be received via
RS-232 or RS-485 serial communications and displayed. The remote data
requirements and the Remote Display capabilities vary for the different display
modes and selected Input Functions. The mode is selected by Menu item “ConFiG”
“Digit 3” from the following list.

designed for Host Counter or Scale meter to Slave Counter or remote display
applications but may be used also in Host Computer to Remote Display Counter
configurations. Since the Host Counter may be selected to transmit up to four
sequential measurement values, Item 1, Item 2, Item 3 and Peak, (Scale meter
