The description sections and FAQ are machine-assisted and can contain errors; where they disagree with the record, the record is correct, and where description sections disagree with each other, Details wins._ ## Summary - Manufacturer: RadiSys - Model: EXM-29 - Condition: Used and in Excellent Condition - Price: $335.00 USD - Availability: In stock, 5 available - Warranty: 1-Year Warranty with 30-Day Return Guarantee - ITAR restricted: No - Shipping weight: 1 lb - Shipping dimensions: 12X9X6 in ## Categories - Test Equipment > Electrical Test > Serial (primary) - Military and Embedded Equipment > Embedded & Industrial > Other Modular ## Details The EXM-29 provides two RS-422/RS-485 serial ports. It is software compatible with the ICS FASTCOMM/422 dual port board, save for two exceptions. First, the EXM-29 is configured via programmable registers on the board, instead of via dip switches. Second, the EXM-29 does not have the capability of sharing interrupts across multiple boards. However, interrupt sharing between ports on the same board is available. Thus, once configured, the EXM-29 is capable of running any software developed for FASTCOMM/422 control, provided different boards use different interrupts.
