Overview
The TS-1800 is a Modbus peripheral device that provides 14 ADC channels, 8 digital outputs, and 16 digital inputs.
Getting Started
Power Requirements
The TS-1800 will operate within a range of 10-28 VDC on either Modbus port. Power supplied on the Modbus port is passed along the bus as an active power rail on the other Modbus port. Do not apply power to both Modbus ports.
Features
TS Modbus Support
The TS-1800 can be utilized as a device in a chain of devices on the RS-485 Modbus port; or, as a single peripheral device pm a USB port. When operating on the USB port, the default device address is 0xf6 (246) and the default bit rate is 1,000,000 bps. When using all Technologic Systems Modbus devices we include functionality to create an arbitrary chain of stock peripherals to automatically enumerate all connected devices, configure them them, and generate an I/O map of all connected devices.
TS Modbus Autoconfiguration
The autoconfiguration works by using the optional mode pin on the RJ45 connector as designated in the MODBUS-2W standard. Technologic Systems uses this to indicate if it is a TS device. If it is asserted (low) to a TS device, then it will allow access to the #Holding Registers at address 0xfe. Normally 0xfe is not a valid address in Modbus, so this will not interfere with other devices.
This will identify the TS Modbus device model and revision, set the first device in the chain to 0x80, and then asserts the mode line to the next port to enumerate the next device. The next device address is set to 0x81, and they continue to increment 1 until no slave responds to the mode line indicating that all salve devices have been discovered. At this point the last device in the chain is configured to enable termination on the RS485 link, and all devices have their speed bumped up to 1M baud.
Funciontality
The TS-1800 provides the following electrically (optically) isolated interfaces:
- 8 Single Ended ADC channels in the range 0-30 or 0-7.5 VDC
- Channels 0-1, 2-3, & 4-7 may be configured in blockes to operate as 4-20 mA instrumentation ports
- 6 Differantial ADC channels in the range +/- 30 or +/- 7.5 VDC
- 8 digital outputs with 6-bit PWM with open drain 500 mA sink capacity
- 16 digital inputs (0-30 VDC)
Each ADC channel can be enabled or disabled individually and can be set for resolution (and associated sample rate) as follows:
- 12 bits per sample @ 240 SPS
- 14 bits per sample @ 60 SPS
- 16 bits per sample @ 15 SPS
Register Interface
Holding Registers
The interface to all Modbus peripheral devices consists of a set of 127 holding registers. These registers are used to configure the device operation, read and write input output parameters, as well as various settings used to configurable Modbus Address, Termination enable, Data Format, and Bit Rate. These settings are common to all of our Modbus peripherals and can be persisted in on-board flash memory.
NOTE: The device operates ONLY in Modbus RTU communications mode. Modbus ASCII is not presently supported.

Output Channel Control Register

|---|---|---|
| 1: Direct DIO output; 0: PWM DIO output | Unused (Reserved) | PWM Value - 0: Off; 63: 98.4% On |
The PWM is scaled in increments of 1/64 (1.56%) per bit in the range of 0/64 through 63/64. To set 100% you must set the Direct DIO Output bit in this register and then set the appropriate bit in the direct output register at holding register 34 (hex 22). NOTE: The PWM range is 0 to 98.4%. The easiest way to do direct per bit control is the set the appropriate output control register (0x12-0x19) to 0x8000 and manupulate the bit in DIO Output (0x22). To use the full range of the PWM, set the appropriate output register bit (0x22) tp 1. Then set the ADC control register to a value from 0 to 63 (0-98.4%) or 0x8000 (100%).

Product Notes
FCC Advisory
This equipment generates, uses, and can radiate radio frequency energy and if not installed and used properly (that is, in strict accordance with the manufacturer's instructions), may cause interference to radio and television reception. It has been type tested and found to comply with the limits for a Class A digital device in accordance with the specifications in Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference when operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference, in which case the owner will be required to correct the interference at his own expense.
If this equipment does cause interference, which can be determined by turning the unit on and off, the user is encouraged to try the following measures to correct the interference:
Reorient the receiving antenna. Relocate the unit with respect to the receiver. Plug the unit into a different outlet so that the unit and receiver are on different branch circuits. Ensure that mounting screws and connector attachment screws are tightly secured. Ensure that good quality, shielded, and grounded cables are used for all data communications. If necessary, the user should consult the dealer or an experienced radio/television technician for additional suggestions. The following booklets prepared by the Federal Communications Commission (FCC) may also prove helpful:
