Hello,
DSU DP Plus, 1103008L3, card not recognized in ACT2300 D4 channel bank. Have 2 DSU cards that do same thing, card firmware is 9103008-5B. Comes up Xd=PCM unknown. E&M cards in same bank work fine. I&M practice for DSU indicates it should work with BCU. BCU is 1150055L2, product revision R, software K. Need 9.6k synchronous RS232 serial. Please post more ACT2300 I&M practices.
Thanks
