  • Page 3: General Information

    The DIGITEL™ Multiple Pump Controller (MPCe) and Large Pump Controller (LPCe) are ion pump power supply controllers. The DIGITEL MPCe is designed to operate up to two ion pumps independently or up to four simultaneously along with and a titanium sublimation pump (TSP) or non-evaporable getter (NEG) pump.
  • Page 4 DIGITEL MPCe. All commands to operate the Remote TSP/NEG Control can be entered using the DIGITEL MPCe display or through serial commands. It can operate in current or power control mode and can be cycled based on time and pressure.
  • Page 5 MPCe/LPCe Users Manual High-Voltage/TSP Filament Interlock Option The remote interlock allows enabling/disabling of either the high voltage outputs or TSP filament firing. The interlock is installed at J506 (on the back panel of the MPCe/LPCe) if the option is installed. A loopback plug is shipped with the option along with a connector kit for custom configuration by the user.

    This section lays out a standard protocol for use on any future Gamma Vacuum instruments that use the standard, and makes recommendations regarding hardware design in areas where software performance may be affected.
  • Page 30 RS-232 lines are typically limited to between 15 and 30 meters (50 - 100 ft.). RS-422 is possible for Apple’s Macintosh computers which utilizes this protocol. Protocol configuration is accomplished by DIP switch settings completed by Gamma Vacuum. Maximum operating baud rate is determined by cable length and the environment near the cable. External noise sources and line loss degrade the signal.
  • Page 31 MPCe/LPCe Users Manual Field Size Comment 1. START character 1 character (byte) ASCII character is ‘~’ (TILDA) Start is the first byte in the command packet and tells remote controllers to start decoding a message. It should be implemented as a #define, so that it can be changed if necessary. As a #define, the character is rarely changed because it is hard coded into the MPC.
