Product Overview
Product Introduction
The host (computer, industrial computer, microcontroller, PLC, HMI touch screen, etc.) can send instructions to control the display content of the display screen through RS485 bus, RS232 or TTL interface. Supports commonly used ASCII protocols and Modbus RTU protocols. This product is mainly used in production lines, industrial control equipment, automotive instruments, warehousing electronic labels, and other fields.
Product features:
1. Multiple communication options available: RS485, RS232, TTL (specify one when ordering), supports MODBUS RTU protocol and simple ASCII protocol, and the protocol is automatically recognized.
2. It can display all kinds of ASCII characters such as integer, minus sign, decimal point, ABCDEFPL, etc. It is a Nixie tube display that supports comprehensive ASCII characters on the market.
3. Support electronic label function, and the initial display content can be set when powered on. Widely used for warehouse tag numbers. For example, displaying
A001, B002, C003, etc.
4. Support stroke brightness adjustment, with 7 brightness levels.
5. Support modifying the baud rate (1200bps -1 15200bps) to cover several commonly used baud rates.
6. Support modifying stop bits and check bits.
7. You can choose to display the initial display content when powered on, such as 0, 485 address, or any content specified by the user
8. A 485 bus can connect 32 Nixie tube (without relay), and 254 can be connected with relay.
9. Provide supporting PC software for easy testing and parameter modification.
The version with a suffix of T for the 10 product model supports displaying clock colons, and this model and feature have been added after the V2.3 version.
11. V2. 4 adds a flashing display function, which can set a certain digit, several digits, and all flashing.
In version 12. V3. 0, some 3 - or 4-bit 232, 485, and TTL communication interface Nixie tube screens have added the function of on load sub meter head,
The main meter head responsible for communicating with the upper computer can carry up to 31 sub meter heads, and in some applications, it can save users more than 50% of the cost without any modifications to the user program.
13. The newly added model with suffix SB is the single bus interface sub meter head, and this kind of Nixie tube screen only needs one 3-core wire and the main meter
Head connection, can be connected by multiple hands, inexpensive, and convenient for wiring. But it cannot be used independently and needs to be linked to the main header with the same number of digits for use.
