  • Page 102: Table 3-1: The Number Of Available Physical Channels

    The data timing generator has two types of channels: logical and physical. Logical channels represent one-bit pattern data. The number of logical channels is 32 (4 channels x 8 slots) for the DTG5078, or 8 (2 channels x 4 slots) for the DTG5274 and DTG5334.
  • Page 103 The number of logical channels that the system can accept is determined by the mainframe (32 for the DTG5078, 8 for the DTG5274, and DTG5334). In the Master-Slave operation mode, the number increases with the number of mainframes.
