Content can be transmitted by the following interfaces:

– Ethernet (two-way communication)

– RS485 (two-way communication)

– RS422 – 232 (with optical isolation)

– CL 20mA digital current loop (with optical isolation)


Displays communicate with the host system using one of the two protocols:

– MODBUS RTU (RS485 interface only)

– Uncomplicated R004 protocol developed by RGB Technology (included in the price of the device at purchase)

Interfaces with two-way communication enable acknowledgment of the receipt of the data by the display.

The specific capabilities of the device are as follows:

  1. Displaying flowing or stationary messages (forced flowing text, forced stationary text, switching on the flow of the text automatically when the messages do not fit on the display).
  2. Available length of messages is from 1 to 100 characters.
  3. 20 different speeds of the text flow.
  4. Two font-faces of standard characters (normal and bold).
  5. Five font-faces of digits with a fixed width dedicated to display numbers, for example finished items, daily schedule, etc.. (two normal font-faces and three bold font-faces).
  6. Displaying current temperature (extra option).
  7. Two modes of brightness adjustment: manual (10 different brightness levels) or automatic (4 different profiles of the brightness sensor displaying the 10 brightness levels according to ambient lighting).


The UPWT-1 is supplied with a steel mounting bracket for wall or cabinet mounting.

Mounting brackets are pre-drilled at 316mm centres with 6x10mm oval holes for fixing with pan-head screws or bolts (not supplied).

Captive cross-head screws at each end of the bracket then slot into the body of the UPWT-1 display before tightening to secure.
