The module mounts directly into any S7-300 rack and receives power via the backplane bus (5 V DC). The 15-pin sub D socket provides a secure connection for RS 422\/485 cables. Ensure proper termination for long cable runs up to 1,200 m. Use the included configuration CD to set protocol parameters (3964(R), ASCII, or printer driver) and Telegram lengths. No external power supply is required.\u003c\/p\u003e\u003ch2\u003eCompatibility \u0026amp; Integration\u003c\/h2\u003e\u003cp\u003eThe \u003cstrong\u003eSiemens 6ES7340-1CH02-0AE0\u003c\/strong\u003e is fully compatible with all Siemens S7-300 CPUs. It supports the 3964(R) and ASCII protocols natively, and can drive standard printers via the built-in printer driver. The module's isolated RS 422\/485 interface ensures noise immunity in harsh industrial environments. For advanced configurations, the FB length of up to 2,700 bytes allows flexible data handling.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eWhen selecting the \u003cstrong\u003eSiemens 6ES7340-1CH02-0AE0\u003c\/strong\u003e, verify that your S7-300 CPU firmware and rack backplane support this revision. For large networks, consider cable length and baud rate requirements (up to 19.2 kbit\/s).
