Configure Epic Serial Module GRV-CSERI-4


Hi all. I’m trying to use the Modbus Integration library with an Epic controller and GRV-CSERI-4 serial module (in slot 0). I’m having trouble figuring out how to configure the module, specifically setting the baud rate. The device I’m communicating with uses RS485 at 57600 baud. I figure the comm handle is tcp (tcp:, as with other PAC serial modules and I can set the RS485 mode (4-wire) in groovManage but for the life of me I cannot find how to set the serial comm parameters. I thought I found it with PAC Manager but it won’t let me access the EPIC since it uses groovManage. Help please!



Page 285 of the PAC Control Users guide has the answers you seek.

Thanks, that worked great! I think I just glazed over that section because I thought it was relevant only to onboard serial ports. I appreciate your help.
