7 / 13 page 7 Electrical Interface To insure reliable encoding performance, the HEDS-9040 and 9140 three channel encoder modules require 2.7 k Ω (±10%) pull-up resistors on output pins 2, 3, and 5 (Channels I, A and B) as shown in Figure 1. These pull-up resistors should be located as close to the encoder mod- ule as possible (within 4 feet). Each of the three encoder module outputs can drive a single TTL load in this con- figuration. Figure 1. Pull-up Resistors on HEDS-9X40 Encoder Module Outputs. Mounting Considerations Figure 2 shows a mounting tolerance requirement for proper operation of the HEDS-9040 and HEDS-9140. The Aligning Recess Centers must be located within a toler- ance circle of 0.005 in. radius from the nominal locations. This tolerance must be maintained whether the module is mounted with side A as the mounting plane using aligning pins (see Figure 5), or mounted with Side B as the mounting plane using an alignment tool (see Figures 3 and 4).
