The GRV-CSERI-4 serial communication module provides 4 independent, isolated serial ports for communication with RS-232 or RS-485 serial devices. The module can communicate with RS-485 serial devices in half-duplex (2-wire transmission) or full-duplex (4-wire transmission) mode.每个端口均可在RS-232和RS-485之间选择，在RS-485模式下具有可配置的终止和偏置。端口0也可以配置为处理调制解调器命令。支持高达1 Mbps的波特率得到支持。Part of the凹槽®EPIC system, the GRV-CSERI-4 mounts on any凹槽EPIC®机壳旁边grv-epic-pr1processor and analog and discrete凹槽我/omodules，，，，to provide the mix of signals you need at any location.凹槽serial modules are directly connected to the processor via the bus on the chassis, so each serial port works like a port that’s built into the processor.凹槽serial modules contain two to four ports, and serial modules can be placed in any of the first four positions on the chassis; so depending on the serial modules you use, you can add up to 8 to 16 serial ports to your GRV-EPIC-PR1.Note that this direct connection means that an EPIC processor can control serial modules on its own chassis, but it cannot control serial modules on a separate EPIC chassis. Other devices, such as a SNAP PAC controller, also cannot control serial modules on an EPIC chassis.笔记：This module requires凹槽EPIC Firmware 1.2.0 or higher on your GRV-EPIC-PR1.
凹槽®serial modules are part of Opto 22's凹槽EPIC®system。This document includes descriptions, specifications, and wiring and dimensional diagrams for these modules, part numbersGRV-CSERI-4Andgrv-ccani-2(CAN bus).。
