Page 4: General Description
General Description This manual only covers the setup of the serial output option. Please refer to the main display’s operating manual for full specifications, installation methods, safety notices etc. You can download manuals from our website. The serial output option allows you to create an isolated RS232 or RS485 signal which provides data proportional to the nett or gross value shown on the front of your display.
Page 5: Installation Hints
Installation hints for best performance This section offers several suggestions which will help you get the best performance from your serial output. Use good quality low capacitance twisted-pair screened signal cable. CAT5 screened twisted-pair is ideal. The cable should be routed away from noisy wiring and devices such as power feeds from inverters, discharge-lighting cables, welder cabling etc, and should preferrably be routed in a dedicated low voltage signalling/instrumentation conduit or cable tray.
Page 6: Serial Output Board Configuring
Serial output board configuring The only board you may need to make adjustments to is the RS485 output option board. You can identify it as an RS485 board, because IC4 will be missing. If the display is at the end of the data cable, you will need to fit the 120 Ohm termination jumper.
Page 7: Setting Up Your Serial Port
Setting up your Serial output port You can choose from :- Baud rates in the range 300 to 115200 Data formats of 8n1,7n1,7e1 or 7o1 Protocol C1 for continuous output (Link “Enable” to “Common” on output connector) Protocol P1 for polled output Protocol P2 for Modbus ASCII mode This feature is available in Easy and Advanced Modes Set1...

Specifications Output signal RS232 or RS485 depending on installed board. Isolation 250 VAC Optically isolated from input, logic, excitation, power, alarms and serial communications ports Response speed Derived from displayed value, which is updated 10 times per second. Any filtering applied to the display will be applied to the serial data output also.
Page 9: Modbus Ascii
Modbus ASCII Select protocol P2, using the previous page. The displayed value is available as a 32 bit 2’s compliment signed integer in registers 0x0000 0x0001 Register 0x0000 Display value low word Register 0x0001 Display value high word The decimal point position is available in the low byte of register 0x001E. The high byte is not currently used, but should be masked off to guarantee compatibility with future firmware releases.
Page 10: Signal Levels
Signal levels These examples show the transmission of a single ASCII character 2C (0010 1100) which is a Comma, so that you can see the voltages in RS485 and RS232 systems. Typical UART output 20 40 80 Stop Idle Start 0 RS485 data line levels 8n1 A(+) A(+)
Page 11: Fault Finding
Fault finding If you are having trouble getting serial data out of the display, first check that you have chosen the correct mode. If you are using Continuous Mode C1 Ensure that you have put a link between terminals 18 and 19 to enable the data output. You can test for data with a simple data monitor which you can make with 2 diodes and a resis- tor, as shown below.
Page 12: Rtc Real Time Clock Option
-RTC Real Time Clock option The -RTC option board consists of a precision calendar/clock chip which is battery-backed to maintain timing during periods of power loss. It can be set to automatically correct for summer and winter time clock shifts. It may be used to include date and time in serial data, along with descriptive text, if required.
