Send or receive Messages?** A: This is a "well behaved" product which seems to meet its specifications. I recommend this product for what it does. It works well for both send and receive. I have several of them. Serial communications can be a bit "tricky" so if you are not familiar with it, I recommend either a book or research on the internet. A full discussion of this subject is a bit beyond this forum. Good luck. **Q: Would it work with rs422?** A: Currently, only RS485 is supported. **Q: this item include the cables on the picture?** A: I don't know what picture you are looking at but - probably. The package included a 4 conductor cable approximately 12 inches long. It is designed to plug into the "TTL" end. **Q: Does the tx go into high-z (tri-state) when not transmitting, so it can be used on modbus or multi-drop lines?** A: Yes. It works well with Modbus multi-drop lines as long as your "master" is working according to spec. For the price, just try it to be sure it works for you. ## Frequently Bought Together - DSD TECH SH-U12 RS485 to TTL 5V Board with MAX13487 Chip for Raspberry Pi Arduino and Other MCU - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - 5 PCS RS-485 MAX485 Transceiver Chip Module TTL to RS-485 Module SCM Development Board --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/71299671-dsd-tech-sh-u12-rs485-to-ttl-5v-board-max13487](https://www.desertcart.tn/products/71299671-dsd-tech-sh-u12-rs485-to-ttl-5v-board-max13487) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-09*
