6.7.1 GM ECx AND C1 BASE STATIONS:
Figure 6-8 shows correct settings for the C1 base station’s “Data From” menu.
Each C1 channel’s Remote ID must match the GM ECx Remote ID setting (see section 6.7) in
order for its VALUE to appear on the desired C1 channel. The GM ECx counts value equals 75
counts, or -15.6%, during CAL MODE. Enabling the C1’s “INPUT MARKER” menu as shown on
the right menu in Figure 6-8 causes the C1 to indicate IN CAL when the GM ECx has its CAL
MODE activated.
Input Req
set for VALUE means this C1 channel reads the GM ECx monitored gas value. If the
Input Req menu is set for BATT this C1 channel reads the battery voltage from the GM ECx with
the same Remote ID. To properly display a GM ECx battery voltage the C1’s engineering unit
range should be 0-5.00 VDC. Even if this channel reads VALUE from the GM ECx, the battery
voltage is displayed at the bottom of this C1 menu as shown in Figure 6-8.
