TELECO TVTRX232-916 Transmitter Instructions
RS232 INTERFACE FOR TVLINK SYSTEMS
Product code
TVTRX232-916
TVTRX232-916 works with the following devices:
- receivers
- transceivers
- transmitters
- temperature, water and sun sensors.
RS232 SERIAL COMMUNICATION SETTINGS:
- Baud rate: 19200
- Data bits: 8
- Parity: none
- Stop bits: 1
- Flow control: none
MEMORY MAP: the device has 50 transmitter codes stored in location 1 to 50 of its memory.
These codes allow TVTRX232-916 work as 50 different transmitters. Every transmitter can send up to 7 channels. These codes are fixed and not modifiable. In user memory area(201 2000) it’s possible to store codes belonging to physical transmitters. To memorize a physical transmitter’s channel can be use command 2 which allow to store a transmitter code via radio in a defined memory location.
WARNINGS
IMPORTANT! READ CAREFULLY THIS INSTRUCTIONS BEFORE INSTALLING AND COMMISSIONING THE PRODUCT. SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE. The product at issue must be installed, commissioned and maintained only by licensed and authorised people, respecting the laws concerning the electrical installations. The manufacturer is not responsible for any damage due to wrong installation or improper use. The manufacturer, Teleco Automation s.r.l, declares that the type of radio equipment is compliant with Directive 2014/53/EU. The full text of the EU compliance declaration is available at the following Internet address: www.telecoautomation.com/ce
INFORMATION TO USERS under art. 14 of the 2012/19/EU DIRECTIVE OF THE EUROPEAN PARLIAMENT AND COUNCIL of 4 July 2012 on waste electrical and electronic equipment (WEEE). The crossed bin symbol on the equipment, or its packaging, indicates that the product must be collected separately from other waste at the end of its useful life and not with mixed urban waste. Please contact your municipality, or local authority, for all information regarding the waste sorting systems available in the area. The retailer is obliged to collect the old equipment free-of-charge when the customer buys a new equivalent equipment. This is to encourage correct recycling/disposal. Appropriate waste sorting for the subsequent recycling, treatment and disposal in an environmentally sound way of the disused equipment avoids negative effects on the environment or human health and favours the re-use or recycling of the equipment’s materials.

Teleco Automation s.r.l. shall caution the user that changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment
RS232 COMMANDS
Checksum: the checksum value of the commands equals the carryless sum of the transmitted bytes. For example, if the hexadecimal values data to send are 54 5B F1 00 07, their sum is 54+5B+F1+00+07 = 1A7 so the checksum is A7.
COMMAND 1: TRANSMIT (THE DEVICE TRANSMITS FOR 300 MS.)
Transmit via radio using one of the 50 codes stored in memory and a specific channel.
| Command string | 1 byte | T’ ( hexadecimal 54) |
|---|---|---|
| ID | 2 bytes | Hex 1 to Hex 50 |
| Channel | 2 bytes | 1-0xFFFF |
| Checksum | 1 byte | Value |
Answer(hexadecimal): 54 06 checksum
Example 1 : Transmitting channel 7 for code stored in location ID=42.
Data to send(hexadecimal)
Answer received: 54 06 5A
COMMAND 2: MEMORIZE A PHYSICAL TRANSMITTER
| Command string | 1 byte | ‘A’ ( hexadecimal 41) |
|---|---|---|
| ID | 2 bytes | Hex 201 to Hex 2000 |
| Checksum | 1 byte | Value |
Wait answer(hexadecimal): 57 06 checksum
Answer after a successful memorization (hexadecimal): 57 06 checksum
NOTE 1: any command shuts down the ‘waiting for a code’ operation.
NOTE 2: to memorize more than one channel belonging to the same transmitter, you have to use the same ID number.
Example 2: memorizing a transmitter on location ID = 500
Data to send(hexadecimal):
Wait answer received: 54 06 5D
Transmission of a channel of the physical transmitter(for example channel 3)
Answer: 54 06 59
(To memorize another channel of the same transmitter must be used the same data to send: 41 01 F4 36)
Receiving a transmitter memorized
When TVTRX232-916 receives and recognizes a radio transmission, it sends on RS232 these data:
| Command string | 1 byte | ‘R’ ( hexadecimal 52) |
|---|---|---|
| ID | 2 bytes | Hex 201 to Hex 2000 |
| Channel | 2 byte | 1-0xFFFF |
| Checksum | 1 byte | Value |
Example 3: receiving the channel 3 of a transmitter(see example 2).
Data received on RS232 (hexadecimal):
COMMAND 3: DELETE MEMORY LOCATION/S
Delete a serial number stored in the range location 201 – 2000
| Command string | 1 byte | ‘C’ ( hexadecimal 43 |
|---|---|---|
| Starting ID | 2 bytes | Hex 201 to Hex 2000 |
| Number of locations to delete | 1 byte | 1-0xFF |
| Checksum | 1 byte | Value |
Successful deletion answer(hexadecimal): 43 06 checksum
Example 4 : deleting one location with ID = 350
Data to send (hexadecimal):
Answer received: 43 06 49
COMMAND 4: DELETE ALL THE MEMORY
Delete all the memory from ID = 201 to 2000
Command string| 10 bytes| DELETE ALL’ ( hexadecimal 44 45 4C 45 54 45 20 41 4C
4C)
---|---|---
Checksum| 1 byte| Value
Successful deletion answer(hexadecimal): 43 06 checksum
Example 5: deleting all the memory
Data to send (hexadecimal:
Answer received: 43 06 49
