A: Yes. When configuring the ACM12 S1 for its maximum transmission speed of 19200 bps, the parity check parameter cannot be configured to \"None\". A parity configuration of \"odd\" or \"even\" must be utilized.\u003c\/p\u003e\n\u003cp\u003eQ: Can this module be installed alongside an ACF11 interface module in the same nest? A: No. The ACM12 S1 cannot be combined with an ACF11 module in the same Communication Module Nest. However, it is fully compatible and can be combined with an ACM11 module within the nest.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eField Wiring Requirements:\u003c\/strong\u003e Utilize a 3-pair shielded cable for field connections, or deploy the dedicated Yokogawa AKB161 cable when interfacing the ACM12 directly with an FA500 unit (limited to a maximum length of 100 m).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Terminal Torques:\u003c\/strong\u003e Connect the external conductors to the 6-pole terminal block utilizing M4 screws.
