The ESMH-DC offers expanded capabilities, including PC control, programmable cycling, auto return, and other features.  

• Computer Control

An RS-232 port is provided to interface with a PC. The ESMH-DC accepts a number of commands pertaining to test stand motion and force gauge functions*. The following additional items are required for PC control:
- Series BG force gauge (more info)
- 09-1056 serial cable (see Optional Equipment)
- 09-1143 multi-function cable (see Optional Equipment)
• Overload Protection Protects a force gauge against overload (requires a Series BG force gauge and 09-1143 multi-function cable). The user programs the desired percentage of full scale of the gauge. Adjustable analog output voltage setting allows the test stand to interface with virtually any force gauge with analog output.
• Auto-return
  The crosshead moves to a limit switch or force set point (requires a Series BG force gauge), stops, and reverses direction at maximum speed to the other limit switch or set point.
• Cycling / Dwell Time
  The crosshead moves up and down between limit switches or force set points (requires a Series BG force gauge). Configurable up to 99,999 cycles. Dwell time allows the operator to program the amount of time, up to 9,999.9 seconds, in 0.1 second intervals, for which the crosshead pauses at limits.
• Programmable LEFT / RIGHT Button Functions
  LEFT and RIGHT button operation can be configured in three user-configurable modes: Maintained: a short push produces continuous motion until STOP is pressed, Momentary: crosshead moves only while the button is pressed, and Auto: short push produces maintained motion, while holding down the button will produce momentary motion.
• Independent Left and Right Speeds
  Programmable independent speeds for left and right directions
• Selectable speed units of measurement (in/min & mm/min)
• Password protection Prevents unauthorized changes to test parameters
