Service Pin button
The Service Pin button is located as shown in Figure 10. The Service Pin
button is used to:
• Identify a device (see “Identifying a device” in the Rover Operation
and Programming guide, EMTX-SVX01B-EN)
• Add a device to the active group (see “Adding a device” in the Rover
Operation and Programming guide)
• Verify PCMCIA communications (see “Verifying PCMCIA communi-
cations” in the Rover Operation and Programming guide)
• Make the Status (green) LED “wink” to verify that the module is com-
municating on the link (see Table 8 on page 27 and “Setting the auto-
wink option” in the Rover Operation and Programming guide)
